  • Jquery hover with animation

    - by Brian
    anyone know how to stop a .hover happening again before the mouseout animation has finished? I have the following code which has 4 anchors. Once hovered over the anchor the related anchor slides in using animation. My problem is you hover out and in quickly, before the square has been set back to 0px it increases the slide distance. <body class="home"> <div id="container"> <a class="page-link homet" id="anim-1"></a> <a class="page-link about" id="anim-2"></a> <a class="page-link portfolio" id="anim-3"></a> <a class="page-link contacts" id="anim-4"></a> <div id="header"> <div id="logo"> </div> <ul id="navigation"> <li><a id="1"></a></li> <li><a id="2"></a></li> <li><a id="3"></a></li> <li><a id="4"></a></li> </ul> </div> <div id="main"> <div id="left-content"> </div> <div id="main-content"> </div> </div> </div> </body> </html> Jquery var cc = { displayAnim : function () { actionLink = $("#container #header #navigation li a"); movePosition = "0"; $("#container a.page-link").css({ position:"absolute", right: 0}); $(actionLink).hoverIntent( function() { circleToReveal = $(this).attr('id'); switch (circleToReveal) { case "1" : movePostion = "386" break; case "2" : moveposition = "514" break; case "3" : movePosition = "643" break; case "4" : movePosition = "400" break; default : movePosition = "772" }; /* console.log(movePosition); */ $("#container #anim-" +circleToReveal+ "").stop().animate({"right": "+="+ movePosition +"px"}, "slow"); }, function() { $("#container #anim-" +circleToReveal+ "").stop().animate({"right": "-="+ movePosition +"px"}, "slow"); } ); } }; $(window).load (function () { $("body").addClass('js'); $("a.pagelink").hide(); cc.displayAnim(); });

  • MooTools event listener disappears after element.innerHTML is changed

    - by acoder
    Hi everyone, I am trying to achieve this task using MooTools. Description: I attached an event listener to "myButton" link. A click on this link initiates an AJAX request and updates "myDiv" content based on the response text. During this request a POST variable is being sent to "button.php", but it's not used at the moment.. (i wish to use it later) OK, as a result, "myDiv" gets exactly the same link with the same ID (myButton) + a random number, so that we could see that each click generates a new number. The problem: After the first click on "myButton", "myDiv" updates correctly, showing a random number. When I click "myButton" for the second time (this time in newly updated div), the div does not refresh anymore. Please note that I need "myButton" to be inside "myDiv", and "myDiv" must be updated (refreshed) after each click without having to refresh the entire page. Can somebody show me how to achieve this task based on this simplified code example? index.html <html> <head> <script type="text/javascript" src="mootools-1.2.4-core-nc.js"></script> <script> window.addEvent('domready', function() { $('myButton').addEvent('click', function(e) { e.stop(); var myRequest = new Request({ method: 'post', url: 'button.php', data: { action : 'test' }, onRequest: function() { $('myDiv').innerHTML = '<img src="images/loading.gif" />'; }, onComplete: function(response) { $('myDiv').innerHTML = response; } }); myRequest.send(); $('myButton').removeEvent('click'); }); }); </script> </head> <body> <div id="myDiv"> <a id="myButton" href="#">Button</a> </div> </body> </html> button.php <a id="myButton" href="#">Button</a> clicked <?php echo rand(1,100); ?>

  • Singleton method not getting called in Cocos2d

    - by jini
    I am calling a Singleton method that does not get called when I try doing this. I get no errors or anything, just that I am unable to see the CCLOG message. Under what reasons would a compiler not give you error and not allow you to call a method? [[GameManager sharedGameManager] openSiteWithLinkType:kLinkTypeDeveloperSite]; The method is defined as follows: -(void)openSiteWithLinkType:(LinkTypes)linkTypeToOpen { CCLOG(@"WE ARE IN openSiteWithLinkType"); //I NEVER SEE THIS MESSAGE NSURL *urlToOpen = nil; if (linkTypeToOpen == kLinkTypeDeveloperSite) { urlToOpen = [NSURL URLWithString:@"http://somesite.com"]; } if (![[UIApplication sharedApplication]openURL:urlToOpen]) { CCLOG(@"%@%@",@"Failed to open url:",[urlToOpen description]); [self runSceneWithID:kMainMenuScene]; } } HERE IS THE CODE TO MY SINGLETON: #import "GameManager.h" #import "MainMenuScene.h" @implementation GameManager static GameManager* _sharedGameManager = nil; @synthesize isMusicON; @synthesize isSoundEffectsON; @synthesize hasPlayerDied; +(GameManager*) sharedGameManager { @synchronized([GameManager class]) { if (!_sharedGameManager) { [[self alloc] init]; return _sharedGameManager; } return nil; } } +(id)alloc { @synchronized ([GameManager class]) { NSAssert(_sharedGameManager == nil,@"Attempted to allocate a second instance of the Game Manager singleton"); _sharedGameManager = [super alloc]; return _sharedGameManager; } return nil; } -(id)init { self = [super init]; if (self != nil) { //Game Manager initialized CCLOG(@"Game Manager Singleton, init"); isMusicON = YES; isSoundEffectsON = YES; hasPlayerDied = NO; currentScene = kNoSceneUninitialized; } return self; } -(void) runSceneWithID:(SceneTypes)sceneID { SceneTypes oldScene = currentScene; currentScene = sceneID; id sceneToRun = nil; switch (sceneID) { case kMainMenuScene: sceneToRun = [MainMenuScene node]; break; default: CCLOG(@"Unknown Scene ID, cannot switch scenes"); return; break; } if (sceneToRun == nil) { //Revert back, since no new scene was found currentScene = oldScene; return; } //Menu Scenes have a value of < 100 if (sceneID < 100) { if (UI_USER_INTERFACE_IDIOM() != UIUserInterfaceIdiomPad) { CGSize screenSize = [CCDirector sharedDirector].winSizeInPixels; if (screenSize.width == 960.0f) { //iPhone 4 retina [sceneToRun setScaleX:0.9375f]; [sceneToRun setScaleY:0.8333f]; CCLOG(@"GM: Scaling for iPhone 4 (retina)"); } else { [sceneToRun setScaleX:0.4688f]; [sceneToRun setScaleY:0.4166f]; CCLOG(@"GM: Scaling for iPhone 3G or older (non-retina)"); } } } if ([[CCDirector sharedDirector] runningScene] == nil) { [[CCDirector sharedDirector] runWithScene:sceneToRun]; } else { [[CCDirector sharedDirector] replaceScene:sceneToRun]; } } -(void)openSiteWithLinkType:(LinkTypes)linkTypeToOpen { CCLOG(@"WE ARE IN openSiteWithLinkType"); NSURL *urlToOpen = nil; if (linkTypeToOpen == kLinkTypeDeveloperSite) { urlToOpen = [NSURL URLWithString:@"http://somesite.com"]; } if (![[UIApplication sharedApplication]openURL:urlToOpen]) { CCLOG(@"%@%@",@"Failed to open url:",[urlToOpen description]); [self runSceneWithID:kMainMenuScene]; } } -(void) test { CCLOG(@"this is test"); } @end

  • jQuery reports incorrect element height in Firefox iframe

    - by Augustus
    Here a short test to demonstrate my problem. I have a page that loads an iframe: <html> <head> <title></title> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.js"></script> </head> <body> <iframe id="iframe" src="box.html" style="width: 100px; height: 100px"></iframe> <script> $('#iframe').bind('load', function () { var div = $(this).contents().find('div'); alert(div.height()); alert(div.innerHeight()); alert(div.outerHeight()); alert(div.outerHeight(true)); }); </script> </body> </html> The iframe (box.html) contains a single styled div: <html> <head> <title></title> <style> div { height: 50px; width: 50px; margin: 5px; padding: 5px; border: 2px solid #00f; background-color: #f00; } </style> </head> <body> <div></div> </body> </html> The four alerts should return 50, 60, 64 and 74, respectively. This works as expected in Safari and Chrome. In FF 3.5.1, they all return 64. This is wrong. Does anyone know how I can force FF/jQuery to return the correct values?

  • Android browser touch events stop display being updated inc. canvas/elements - How to work around?

    - by Ed Kirk
    On some android's native browser touching the page seems to stop the display from being updated until the finger is released. This occurs for both html element based animation (switching classes) and for canvas based animation. It does not however stop normal js execution and other events are fired as normal. On devices with this problem the dolphin browser also seems effected (not firefox though). Touchstart/move both have preventDefault() fired as well as stopPropergation(), cancelBubble = true; and e.returnValue = false;. In the CSS webkit selection has also been disabled. The page will not scroll. A similar question has been asked here: Does Android browser lock DOM on touchStart? but I'd like to find out if this behaviour can be overcome, or at least to discover what devices will be effected by the problem, is it a device or version android issue? If you cannot answer the question running the demo and reporting your experience along with your device model and useragent (displayed at bottom of demo page) as a comment might help others or myself answer the question. Here is a demo and steps to reproduce the behaviour. A QR code for the link can be found here https://s3-eu-west-1.amazonaws.com/canvas-test-pd/tmp.png. https://s3-eu-west-1.amazonaws.com/canvas-test-pd/index.html The web page has a canvas at the top and a div with a background image at the bottom. Every second the canvas is cleared and a different image displayed and the div has it's class switched (both toggle between 0 and 1 pngs). Once this has toggled a few times place your finger on the canvas (the top grey box) and hold it there. Wait to see if the animation continues (sometimes it will once or twice then stops) and if there are any visual distortions. Update It seems that the Galaxy Tab running 3.2 requires handlers for touchstart/end of document, not just required divs for the screen to continue updating the display. Thanks jimpic. I'm starting to believe it's an issue caused by manufacturers skins, although this is difficult to prove.

  • Lift session valid ajax callback from a static javascript

    - by ChrisJamesC
    I am currently implementing a graph visualisation tool using lift on the server side and d3 ( a javascript visualisation framework) for all the visualisation. The problem I have is that in the script I want to get session dependent data from the server. So basically, my objective is to write lift-valid ajax callbacks in a static js script. Here is what I tried so far: What I have tried so far If you feel that the best solution is one that I already tried feel free to post a detailed answer telling me how to use it exactly and how it completely solves my problem. REST interface Usually what one would do to get data from a javascript function in lift is to create a REST interface. However this interface will not be linked to any session. This is the solution I got from my previous question: Get json data in d3 from lift snippet Give function as argument of script Another solution would be to give the ajaxcallback as an argument of the main script called to generate my graph. However I expect to have a lot of callbacks and I don't want to have to mess with the arguments of my script. Write the ajax callback in another script using lift and call it from the main script This solution, which is similar to a hidden text input is probably the more likely to work. However it is not elegant and it would mean that I would have to load a lot of scripts on load, which is not really conveniant. Write the whole script in lift and then serve it to the client This solution can be elegant, however my script is very long and I would really prefer that it remainss static. What I want On client side While reviewing the source code of my webpage I found that the callback for an ajaxSelect is: <select onchange="liftAjax.lift_ajaxHandler('F966066257023LYKF4=' + encodeURIComponent(this.value), null, null, null)" name="F96606625703QXTSWU" id="node_delete" class="input"> Moreover, there is a variable containing the state of the page in the end of the webpage: var lift_page = "F96606625700QRXLDO"; So, I am wondering if it is possible to simulate that my ajaxcall is valid using this liftAjax.lift_ajaxHandler function. However I don't know the exact synthax to use. On server side Since I "forged" a request on client side, I would now like to get the request on client side and to dispatch it to the correct function. This is where the LiftRules.dispatch object seems the best solution: when it is called, all the session management has been made (the request is authentified and linked to a session), however I don't know how to write the correct piece of code in the append function. Remark In lift all names of variables are changed to a random string in order to increase the security, I would like to have the same behavior in my application even if that will probably mean that I will have to "give" the javascript these values. However an array of 15 string values is still a better tradeoff than 15 functions as argument of a javascript function.

  • iPad web app: Prevent input focus AFTER ajax call

    - by Mike Barwick
    So I've read around and can't for the life of me figure out of to solve my issue effectively. In short, I have a web app built for the iPad - which works as it should. However, I have an Ajax form which also submits as it should. But, after the callback and I clear/reset my form, the "iPad" automatically focuses on an input and opens the keyboard again. This is far from ideal. I managed to hack my way around it, but it's still not perfect. The code below is run on my ajax callback, which works - except there's still a flash of the keyboard quickly opening and closing. Note, my code won't work unless I use setTimeout. Also, from my understanding, document.activeElement.blur(); only works when there's a click event, so I triggered one via js. IN OTHER WORDS, HOW DO I PREVENT THE KEYBOARD FROM REOPENING AFTER AJAX CALL ON WEB APP? PS: Ajax call works fine and doesn't open the keyboard in Safari on the iPad, just web app mode. Here's my code: hideKeyboard: function () { // iOS web app only, iPad IS_IPAD = navigator.userAgent.match(/iPad/i) != null; if (IS_IPAD) { $(window).one('click', function () { document.activeElement.blur(); }); setTimeout(function () { $(window).trigger('click'); }, 500); } } Maybe it's related to how I'm clearing my forms, so here's that code. Note, all inputs have tabindex="-1" as well. clearForm: function () { // text, textarea, etc $('#campaign-form-wrap > form')[0].reset(); // checkboxes $('input[type="checkbox"]').removeAttr('checked'); $('#campaign-form-wrap > form span.custom.checkbox').removeClass('checked'); // radio inputs $('input[type="radio"]').removeAttr('checked'); $('#campaign-form-wrap > form span.custom.radio').removeClass('checked'); // selects $('form.custom .user-generated-field select').each(function () { var selection = $(this).find('option:first').text(), labelFor = $(this).attr('name'), label = $('[for="' + labelFor + '"]'); label.find('.selection-choice').html(selection); }); optin.hideKeyboard(); }

  • Layout issue regarding a JQuery smoothDivScroll

    - by MichaelMcCabe
    Hi all. I have been scratching my head for a while on this one. I dont really play around with HTML formatting that often. I have a smoothDivScroll using JQuery (http://maaki.com/thomas/SmoothDivScroll/) to scroll through dynamically generated images. What I want it for, is to have multiple small images lined up right next to each other, and each image has a section of writting underneath. about 25 images, 140px width each in a 7560px span. I acheived this great by putting a table inside the div, and each image inside a<td>.This works problem i have, is that i need the slider to start from the furthest RIGHT image, and slide automatically left. This is acheived by (if you look at the link above) - startAtElementId: But if I am using a table inside the div, it is taking the TABLE as a element and not the TD... so it doesnt work. I know this because if I change every image to be inside tables (i.e 25 tables), it works... but obviously then the formatting is not how I want. Can anyone think of a way I can use this slider (modifications to the js code or not), with 25 images that NEED to be right next to each other, no gap. I guess this is more of a formatting question, than about the slider. Because I only know ONE way of doing what I want, and thats to have below which will not alow me to set startAtElementId. <div class="scrollableArea"> <table width="7560px" class="index-body"> <tr> <td width="140px"><center><a onclick="__doPostBack('getEarlierDate');" ><img src="../images/olderGraphs.gif" width="140" height="60"></a>Click for more</center></td> <td width="300px"><center><a onclick="__doPostBack('chartClicked25');" ><cewolf:img chartid="verticalbar25" renderer="cewolf" width="300" height="60"/></a><c:out value="${date25}"/></center></td> <td width="300px"><center><a onclick="__doPostBack('chartClicked24');" ><cewolf:img chartid="verticalbar24" renderer="cewolf" width="300" height="60"/></a><c:out value="${date24}"/></center></td> and so on

  • jQuery multiple class selection

    - by morpheous
    I am a bit confused with this: I have a page with a set of buttons (i.e. elements with class attribute 'button'. The buttons belong to one of two classes (grp1 and grp2). These are my requirements For buttons with class enabled, when the mouse hovers over them, a 'button-hover' class is added to them (i.e. the element the mouse is hovering over). Otherwise, the hover event is ignored When one of the buttons with class grp2 is clicked on (it has to be 'enabled' first), then I disable (i.e. remove the 'enabled' class for all elements with class 'enabled' (should probably selecting for elements with class 'button' AND 'enabled' - but I am having enough problems as it is, so I need to keep things simple for now). This is what my page looks like: <html> <head> <title>Demo</title> <style type="text/css" .button {border: 1px solid gray; color: gray} .enabled {border: 1px solid red; color: red} .button-hover {background-color: blue; } </style> <script type="text/javascript" src="jquery.js"></script> </head> <body> <div class="btn-cntnr"> <span class="grp1 button enabled">button 1</span> <span class="grp2 button enabled">button 2</span> <span class="grp2 button enabled">button 3</span> <span class="grp2 button enabled">button 4</span> </div> <script type="text/javascript"> /* <![CDATA[ */ $(document).ready(function(){ $(".button.enabled").hover(function(){ $(this).toggleClass('button-hover'); }, function() { $(this).toggleClass('button-hover'); }); $('.grp2.enabled').click(function(){ $(".grp2").removeClass('enabled');} }); /* ]]> */ </script> </body> </html> Currently, when a button with class 'grp2' is clicked on, the other elements with class 'grp2' have the 'enabled' class removed (works correctly). HOWEVER, I notice that even though the class no longer have a 'enabled' class, SOMEHOW, the hover behaviour is still applied to these elemets (WRONG). Once an element has been 'disabled', I no longer want it to respond to the hover() event. How may I implement this behavior, and what is wrong with the code above (i.e. why is it not working? (I am still learning jQuery)

  • Cross-site request forgery protections: Where do I put all these lines?

    Hello, I was looking for a python code that would be able to log in from "Google App Engine" to some of my accounts on some websites (like yahoo or eBay) and was given this code: import urllib, urllib2, cookielib url = "https://login.yahoo.com/config/login?" form_data = {'login' : 'my-login-here', 'passwd' : 'my-password-here'} jar = cookielib.CookieJar() opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(jar)) form_data = urllib.urlencode(form_data) # data returned from this pages contains redirection resp = opener.open(url, form_data) # yahoo redirects to http://my.yahoo.com, so lets go there instead resp = opener.open('http://mail.yahoo.com') print resp.read() Unfortunately, this code didn't work, so I asked another question here and one supporter among other things said this: "You send MD5 hash and not plain password.

EDIT: the output to my logfile works just fine: Content-type: text/plain The Query String is: fname=hello&sname=world I just noticed that if i open it with IE8 i get the query-string. But only on the first "keydown" after that IE does nothing.

  • Setting background-image with javascript

    - by Mattoe3k
    In chrome, safari, and opera setting the background image to an absolute reference such as: "/images/image.png" changes it to "http://sitepath/images/image.png". It does not do this in firefox. Is there any way to avoid this behavior, or is it written into the browser's javascript engine? Using jquery to set the background-image also does this problem. The problem is that I am posting the HTML to a php script that needs the urls in this specific format. I know that setting the image path relative fixes this, but I can't do that. The only other alternative would be to use a regexp. to convert the urls. Thanks. Test this in firefox, and chrome / webkit browser: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <body> <div style="height:400px;width:400px;background-image:url(/images/images/logo.gif);"> </div> <br /> <br /> <div id="test" style="height:400px;width:400px;"> </div> <script type="text/javascript" src="/javascripts/jquery.js"></script> <script type="text/javascript"> $(document).ready(function(){ $("#test").css('background-image',"url(/images/images/logo.gif)"); alert(document.getElementById('test').style.backgroundImage); }); </script> </body> </html>

  • XSLT split text and preserve HTML tags

    - by Lycaon
    I have an xml that has a description node: <config> <desc>A <b>first</b> sentence here. The second sentence with some link <a href="myurl">The link</a>. The <u>third</u> one.</desc> </config> I am trying to split the sentences using dot as separator but keeping in the same time in the HTML output the eventual HTML tags. What I have so far is a template that splits the description but the HTML tags are lost in the output due to the normalize-space and substring-before functions. My current template is given below: <xsl:template name="output-tokens"> <xsl:param name="sourceText" /> <!-- Force a . at the end --> <xsl:variable name="newlist" select="concat(normalize-space($sourceText), ' ')" /> <!-- Check if we have really a point at the end --> <xsl:choose> <xsl:when test ="contains($newlist, '.')"> <!-- Find the first . in the string --> <xsl:variable name="first" select="substring-before($newlist, '.')" /> <!-- Get the remaining text --> <xsl:variable name="remaining" select="substring-after($newlist, '.')" /> <!-- Check if our string is not in fact a . or an empty string --> <xsl:if test="normalize-space($first)!='.' and normalize-space($first)!=''"> <p><xsl:value-of select="normalize-space($first)" />.</p> </xsl:if> <!-- Recursively apply the template for the remaining text --> <xsl:if test="$remaining"> <xsl:call-template name="output-tokens"> <xsl:with-param name="sourceText" select="$remaining" /> </xsl:call-template> </xsl:if> </xsl:when> <!--If no . was found --> <xsl:otherwise> <p> <!-- If the string does not contains a . then display the text but avoid displaying empty strings --> <xsl:if test="normalize-space($sourceText)!=''"> <xsl:value-of select="normalize-space($sourceText)" />. </xsl:if> </p> </xsl:otherwise> </xsl:choose> </xsl:template> and I am using it in the following manner: <xsl:template match="config"> <xsl:call-template name="output-tokens"> <xsl:with-param name="sourceText" select="desc" /> </xsl:call-template> </xsl:template> The expected output is: <p>A <b>first</b> sentence here.</p> <p>The second sentence with some link <a href="myurl">The link</a>.</p> <p>The <u>third</u> one.</p>

  • jQuery: Giving each matched element an unique ID

    - by AnGafraidh
    I am writing an 'inline translator' application to be used with a cloud computing platform to extend non-supported languages. The majority of this uses jQuery to find the text value, replace it with the translation, then append the element with a span tag that has an unique ID, to be used elsewhere within the application. The problem arises however, when there are more than one element, say , that have the exact same value to be translated (matched elements). What happens in the function in question is that it puts all matched elements in the same span, taking the second, third, fourth, etc. out of their parent tags. My code is pretty much like this example: <script src='jquery-1.4.2.js'></script> <script> jQuery.noConflict(); var uniqueID='asdfjkl'; jQuery(window).ready(function() { var myQ1 = jQuery("input[id~=test1]"); myClone=myQ1.clone(); myClone.val('Replaced this button'); myQ1.replaceWith('<span id='+uniqueID+'></span>'); jQuery('#'+uniqueID).append(myClone); }); </script> <table> <tr><td> <input id='test1' type='button' value="I'm a button!"></input> &nbsp; <input id='test2' type='button' value="And so am I"></input> </tr></td> <tr><td> <input id='test1' type='button' value="I'm a button!"></input> </tr></td> </table> As a workaround, I've experimented with using a loop to create a class for each span, rising in increment until jQuery("input[id~=test1]").length, but I can't seem to get anything I do to work. Is there any way to give each matched element an unique ID? My fluency in jQuery is being put to the test! Thanks for any help in advance. Aaron

  • Create a Counter within a For-Loop?

    - by Todd Hartman
    I am a novice programmer and apologize upfront for the complicated question. I am trying to create a lexical decision task for experimental research, in which respondents must decide if a series of letters presented on the screen make a "word" or "not a word". Everything works reasonably well except for the bit where I want to randomly select a word (category A) or nonword (category B) for each of 80 trials from a separate input file (input.txt). The randomization works, but some elements from each list (category A or B) are skipped because I have used "round.catIndex = j;" where "j" is a loop for each successive trial. Because some trials randomly select from Category A and other from Category B, "j" does not move successively down the list for each category. Instead, elements from the Category A list may be selected from something like 1, 2, 5, 8, 9, 10, and so on (it varies each time because of the randomization). To make a long story short(!), how do I create a counter that will work within the for-loop for each trial, so that every word and nonword from Category A and B, respectively, will be used for the lexical decision task? Everything I have tried thus far does not work properly or breaks the javascript entirely. Below is my code snippet and the full code is available at http://50.17.194.59/LDT/trunk/LDT.js. Also, the full lexical decision task can be accessed at http://50.17.194.59/LDT/trunk/LDT.php. Thanks! function initRounds() { numlst = []; for (var k = 0; k<numrounds; k++) { if (k % 2 == 0) numlst[k] = 0; else numlst[k] = 1; } numlst.sort(function() {return 0.5 - Math.random()}) for (var j = 0; j<numrounds; j++) { var round = new LDTround(); if (numlst[j] == 0) { round.category = input.catA.datalabel; } else if (numlst[j] == 1) { round.category = input.catB.datalabel; } // pick a category & stimulus if (round.category == input.catA.datalabel) { round.itemtype = input.catA.itemtype; round.correct = 1; round.catIndex = j; } else if (round.category == input.catB.datalabel) { round.itemtype = input.catB.itemtype; round.correct = 2; round.catIndex = j; } roundArray[i].push(round); } return roundArray; }

  • [NHibernate and ASP.NET MVC] How can I implement a robust session-per-request pattern in my project,

    - by Guillaume Gervais
    I'm currently building an ASP.NET MVC project, with NHibernate as its persistance layer. For now, some functionnalities have been implemented, but only use local NHibernate sessions: each method that accessed the database (read or write) needs to instanciate its own NHibernate session, with the "using()" directive. The problem is that I want to leverage NHibernate's Lazy-Loading capabilities to improve the performance of my project. This implies an open NHibernate session per request until the view is rendered. Furthermore, simultaneous request must be supported (multiple Sessions at the same time). How can I achieve that as cleanly as possible? I searched the Web a little bit and learned about the session-per-request pattern. Most of the implementations I saw used some sort of Http* (HttpContext, etc.) object to store the session. Also, using the Application_BeginRequest/Application_EndRequest functions is complicated, since they get fired for each HTTP request (aspx files, css files, js files, etc.), when I only want to instanciate a session once per request. The concern that I have is that I don't want my views or controllers to have access to NHibernate sessions (or, more generally, NHibernate namespaces and code). That means that I do not want to handle sessions at the controller level nor the view one. I have a few options in mind. Which one seems the best ? Use interceptors (like in GRAILS) that get triggered before and after the controller action. These would open and close sessions/transactions. Is it possible in the ASP.NET MVC world? Use the CurrentSessionContext Singleton provided by NHibernate in a Web context. Using this page as an example, I think this is quite promising, but that still requires filters at the controller level. Use the HttpContext.Current.Items to store the request session. This, coupled with a few lines of code in Global.asax.cs, can easily provide me with a session on the request level. However, it means that dependencies will be injected between NHibernate and my views (HttpContext). Thank you very much!

  • Finding open contiguous blocks of time for every day of a month, fast

    - by Chris
    I am working on a booking availability system for a group of several venues, and am having a hard time generating the availability of time blocks for days in a given month. This is happening server-side in PHP, but the concept itself is language agnostic -- I could be doing this in JS or anything else. Given a venue_id, month, and year (6/2012 for example), I have a list of all events occurring in that range at that venue, represented as unix timestamps start and end. This data comes from the database. I need to establish what, if any, contiguous block of time of a minimum length (different per venue) exist on each day. For example, on 6/1 I have an event between 2:00pm and 7:00pm. The minimum time is 5 hours, so there's a block open there from 9am - 2pm and another between 7pm and 12pm. This would continue for the 2nd, 3rd, etc... every day of June. Some (most) of the days have nothing happening at all, some have 1 - 3 events. The solution I came up with works, but it also takes waaaay too long to generate the data. Basically, I loop every day of the month and create an array of timestamps for each 15 minutes of that day. Then, I loop the time spans of events from that day by 15 minutes, marking any "taken" timeslot as false. Remaining, I have an array that contains timestamp of free time vs. taken time: //one day's array after processing through loops (not real timestamps) array( 12345678=>12345678, // <--- avail 12345878=>12345878, 12346078=>12346078, 12346278=>false, // <--- not avail 12346478=>false, 12346678=>false, 12346878=>false, 12347078=>12347078, // <--- avail 12347278=>12347278 ) Now I would need to loop THIS array to find continuous time blocks, then check to see if they are long enough (each venue has a minimum), and if so then establish the descriptive text for their start and end (i.e. 9am - 2pm). WHEW! By the time all this looping is done, the user has grown bored and wandered off to Youtube to watch videos of puppies; it takes ages to so examine 30 or so days. Is there a faster way to solve this issue? To summarize the problem, given time ranges t1 and t2 on day d, how can I determine the remaining time left in d that is longer than the minimum time block m. This data is assembled on demand via AJAX as the user moves between calendar months. Results are cached per-page-load, so if the user goes to July a second time, the data that was generated the first time would be reused. Any other details that would help, let me know. Edit Per request, the database structure (or the part that is relevant here) *events* id (bigint) title (varchar) *event_times* id (bigint) event_id (bigint) venue_id (bigint) start (bigint) end (bigint) *venues* id (bigint) name (varchar) min_block (int) min_start (varchar) max_start (varchar)

  • color letters in a div

    - by Growler
    I've created a palindrome checker. I want to take it one step further and show the letters being compared as it is being checked. HTML: <p id="typing"></p> <input type="text" id="textBox" onkeyup="pal(this.value);" value="" /> <div id="response"></div> <hr> <div id="palindromeRun"></div> JS: To do this, I run the recursive check... Then if it is a palindrome, I run colorLetters(), which I'm trying to highlight in green each letter as it is being checked. Right now it is just rewriting palindromeRun's HTML with the first letter. I know this is because of the way I'm resetting its HTML. I don't know how to just grab the first and last letter, change only those letters' css, then increment i and j on the next setTimeout loop. var timeout2 = null; function pal (input) { var str = input.replace(/\s/g, ''); var str2 = str.replace(/\W/, ''); if (checkPal(str2, 0, str2.length-1)) { $("#textBox").css({"color" : "green"}); $("#response").html(input + " is a palindrome"); $("#palindromeRun").html(input); colorLetters(str2, 0, str2.length-1); } else { $("#textBox").css({"color" : "red"}); $("#response").html(input + " is not a palindrome"); } if (input.length <= 0) { $("#response").html(""); $("#textBox").css({"color" : "black"}); } } function checkPal (input, i, j) { if (input.length <= 1) { return false; } if (i === j || ((j-i) == 1 && input.charAt(i) === input.charAt(j))) { return true; } else { if (input.charAt(i).toLowerCase() === input.charAt(j).toLowerCase()) { return checkPal(input, ++i, --j); } else { return false; } } } function colorLetters(myinput, i, j) { if (timeout2 == null) { timeout2 = setTimeout(function () { console.log("called"); var firstLetter = $("#palindromeRun").html(myinput.charAt(i)) var secondLetter = $("#palindromeRun").html(myinput.charAt(j)) $(firstLetter).css({"color" : "red"}); $(secondLetter).css({"color" : "green"}); i++; j++; timeout2=null; }, 1000); } } Secondary: If possible, I'd just like to have it colors the letters as the user is typing... I realize this will require a setTimeout on each keyup, but also am not sure how to write this.

  • Google Maps API - Marker not showing

    - by popnbrown
    I'm trying to add markers for every single row from a table, that sits on the page. The page is http://www.sravanks.com/first/2013ftcmap.php This is the JS code that's loading the markers: $(document).ready(function() { var mapOptions = { center: new google.maps.LatLng(39.740, -89.503), zoom: 7 }; var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions); var infowindow = new google.maps.InfoWindow(); /* City Markers */ var cityCircle = new Array(); var i = 0; $.each($('.events tr'), function(index, value) { var name = $(this).find('td:first()').html(); var address = $(this).find('.address').html(); var linkUrl = "http://www.sravanks.com/first/geocode.php?address=" + address; $.ajax({ url: linkUrl }).done(function(data){ var json = $.parseJSON(data.substring(0, data.length-1)); lat = json.results[0].geometry.location.lat; lng = json.results[0].geometry.location.lng; var latlng = new google.maps.LatLng(lat, lng); var marker = new google.maps.Marker({ position: latlng, map: map, icon: 'map-pointer-medium.gif' }); google.maps.event.addListener(marker, 'click', function() { infowindow.setContent(name); infowindow.open(map, marker); cityCircle[i] = new google.maps.Circle({strokeColor: '#00FF00', strokeOpacity: 0.8, strokeWeight: 2, fillColor: '#00FF00', fillOpacity: 0.35, map: map, center: latlng, radius: 144841}); i++; }); }); }); /*Team Markers*/ var markers = {}; var teamName, teamNumber, lat, lng, content; $.each($('.list tr'), function(index, value) { teamName = $(this).find('td.name').html(); teamNumber = $(this).find('td.number').html(); markers[teamNumber] = {}; lat = parseFloat($(this).find('td.lat').html()); lng = parseFloat($(this).find('td.lng').html()); content = "Name: " + teamName + "<br />Number: " + teamNumber; markers[teamNumber]['latlng'] = new google.maps.LatLng(lat, lng); markers[teamNumber]['marker'] = new google.maps.Marker({ position: markers[teamNumber]['latlng'], map: map }); google.maps.event.addListener(markers[teamNumber]['marker'], 'click', function() { infowindow.setContent(content); infowindow.open(map, markers[teamNumber]['marker']); }); }); google.maps.event.addListener(infowindow, 'closeclick', function() { for(var i=0;i<cityCircle.length;i++){ cityCircle[i].setMap(null); } }); }); I've got no errors, but the Team Markers do not show up.

  • jQuery - Sorting an array?

    - by Probocop
    Hi, I'm using Ajax to get some XML, and then filling in some fields on a form with the results. There is a numerical field on the form and I would like to sort the results by this number (highest first). How would I go about doing this in jQuery? My js function code is currently: function linkCounts() { ws_url = "http://archreport.epiphanydev2.co.uk/worker.php?query=linkcounts&domain="+$('#hidden_the_domain').val(); $.ajax({ type: "GET", url: ws_url, dataType: "xml", success: function(xmlIn){ results = xmlIn.getElementsByTagName("URL"); for ( var i = 0; i < results.length; i++ ) { $("#tb_domain_linkcount_url_"+(i+1)).val($(results[i].getElementsByTagName("Page")).text()); $("#tb_domain_linkcount_num_"+(i+1)).val($(results[i].getElementsByTagName("Links")).text()); } $('#img_linkcount_worked').attr("src","/images/worked.jpg"); }, error: function(){$('#img_linkcount_worked').attr("src","/images/failed.jpg");} }); } The Links tag is the one I'm wanting to sort it on. Thanks For reference the XML that's getting returned is like the following: <?xml version="1.0" encoding="utf-8" standalone="yes"?> <Response> <ResponseCode>1</ResponseCode> <ResponseStatus>OK</ResponseStatus> <ReportId>2</ReportId> <UrlChecked /> <MaxLinks>75</MaxLinks> <PagesFound>121</PagesFound> <URLs> <URL> <Page>http://www.epiphanysolutions.co.uk/blog</Page> <Links>78</Links> </URL> <URL> <Page>http://www.epiphanysolutions.co.uk/blog/</Page> <Links>78</Links> </URL> <URL> <Page>http://www.epiphanysolutions.co.uk/blog/author/daniel-peden/</Page> <Links>78</Links> </URL> <URL> <Page>http://www.epiphanysolutions.co.uk/blog/author/daniel-peden/page/2/</Page> <Links>78</Links> </URL> </URLS> </Response>
