  • YouTube API, jQuery attr won't swap element attributes (I think) in IE, but works in FF

    - by Anthony
    JavaScript (jQuery) function display_youtube(new_url) { $('#movie_url').removeAttr('value'); $('#embed_url').removeAttr('src'); $(document).ready(function() { $('#movie_url').attr('value', new_url); $('#embed_url').attr('src', new_url); $('#shade').css('display', 'block'); $('#youtube_player').css('display', 'block'); $('#exit_youtube').css('display', 'block'); }); } HTML <object width="720" height="480"> <param id="movie_url" name="movie" value="http://www.youtube.com/v/_eaToCSn7yU?f=user_uploads&app=youtube_gdata&autoplay=0" /> <param name="allowFullScreen" value="true" /> <param name="allowscriptaccess" value="always" /> <embed id="embed_url" src="http://www.youtube.com/v/_eaToCSn7yU?f=user_uploads&app=youtube_gdata&autoplay=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="720" height="480" /> </object> Hyperlink <a href="javascript:display_youtube('http://www.youtube.com/v/_eaToCSn7yU?f=user_uploads&app=youtube_gdata&autoplay=1');">Click Here for Fun!</a> What I've done is parsed YouTube's API for the videos on my user channel. The hyperlink above is php generated, meant to trigger the above JavaScript function, and swap the url from attributes contained in ids "movie_url" and "embed_url". Works just like it should in FF, but IE will only perform the .css commands. My guess? IE doesn't like me assigning IDs to PARAM and EMBED, perhaps? What do you think?

  • set/clear interval issue

    - by 3gwebtrain
    HI, i am using the following code to show a link which is inside the li element. the constrain is, once the mouse enter into li element, and if it's stay inside 3sec, then it need to show. once i leave from li element, immateriality it should hide. for this, i am using : var showTimeOut; var thisElement $('.user-list li').live('mouseover',function(){ thisElement = $(this).children('a.copier-link'); showTimeOut = setInterval(function(){ thisElement.css({'display':'block'}); },3000); }) $('.user-list li').live('mouseleave',function(){ clearInterval(showTimeOut); thisElement.hide(); }) It's work fine. But the problem is, while i cross the li element with just a second, even the interval is calling, and showing the link. but i need to show only, if i stay inside 3sec and it need to hide there after, again i stay back 3sec. anything wrong with my code?, else any one give me the best suggestion? Thanks.

  • Jquery toggle event is messing with checkbox value

    - by John McCollum
    Hi all, I'm using Jquery's toggle event to do some stuff when a user clicks a checkbox, like this: $('input#myId').toggle( function(){ //do stuff }, function(){ //do other stuff } ); The problem is that the checkbox isn't being ticked when I click on the checkbox. (All the stuff I've put into the toggle event is working properly.) I've tried the following: $('input#myId').attr('checked', 'checked'); and $(this).attr('checked', 'checked'); and even simply return true; But nothing is working. Can anyone tell me where I'm going wrong? Edit - thanks to all who replied. Dreas' answer very nearly worked for me, except for the part that checked the attribute. This works perfectly (although it's a bit hacky) $('input#myInput').change(function () { if(!$(this).hasClass("checked")) { //do stuff if the checkbox isn't checked $(this).addClass("checked"); return; } //do stuff if the checkbox isn't checked $(this).removeClass('checked'); }); Thanks again to all who replied.

  • How to fetch particular element from string after splitting it, using XSLT split() ?

    - by Vijay
    Hi All, I have one query regarding XSLT functions. I am using split function to fetch values from a string. I am using separator as "*". e.g. String : {"item1*item2*item3*item4"} split function I am using is as; <xsl:template name="SplitItemsCollection"> <xsl:param name="list" select="''"/> <xsl:param name="separator" select="'*'"/> <xsl:if test="not($list = '' or $separator = '')"> <xsl:variable name="head" select="substring-before(concat($list, $separator), $separator)"/> <xsl:variable name="tail" select="substring-after($list, $separator)"/> <xsl:value-of select="$head"/> <xsl:call-template name="split"> <xsl:with-param name="list" select="$tail"/> <xsl:with-param name="separator" select="$separator"/> </xsl:call-template> </xsl:if> </xsl:template> This function returns me all the items. Is there any way to fetch particular item from these separated items ? Say I want to fetch item3. Can we do it directly ? Thanks in advance.

  • How to detect what allowed character in current Regular Expression by using JavaScript?

    - by Soul_Master
    In my web application, I create some framework that use to bind model data to control on page. Each model property has some rule like string length, not null and regular expression. Before submit page, framework validate any binded control with defined rules. So, I want to detect what character that is allowed in each regular expression rule like the following example. "^[0-9]$" allow only digit characters like 1, 2, 3. "^[a-zA-Z_][a-zA-Z_-0-9]+$" allow only a-z, - and _ characters However, this function should not care about grouping, positioning of allowed character. It just tells about possible characters only. By the way, complex regular expression like find two words near(\bword1\W+(?:\w+\W+){1,6}?word2\b) must be ignore to verify and it should return any characters is possible. Do you have any idea for creating this function? PS. I know it easy to create specified function like numeric only for allowing only digit characters. But I need share/reuse same piece of code both data tier(contains all model validator) and UI tier without modify anything. Thanks

  • PHP Magic faster than simply setting the class attribute?

    - by Marc Trudel
    Well, not exactly that, but here is an example. Can anyone explain the difference between B and C? How can it be faster to use a magic function to dynamically set a value instead of simply setting the value in the attribute definition? Here is some code: [root@vm-202-167-238-17 ~]# cat test.php; for d in A B C; do echo "------"; ./test.php $d; done; #!/usr/bin/php <?php $className = $argv[1]; class A { public function __get($a) { return 5; } } class B { public $a = 5; } class C { public function __get($a) { $this->a = 5; return 5; } } $a = new $className; $start = microtime(true); for ($i=0; $i < 1000000; $i++) $b = $a->a; $end = microtime(true); echo (($end - $start) * 1000) ." msec\n"; ------ 598.90794754028 msec ------ 205.48391342163 msec ------ 189.7759437561 msec

  • Simple problem with mod_rewrite in the Fat Free Framework

    - by ian
    I am trying to setup and learn the Fat Free Framework for PHP. http://fatfree.sourceforge.net/ It's is fairly simple to setup and I am running it on my machine using MAMP. I was able to get the 'hello world' example running just fin: require_once 'path/to/F3.php'; F3::route('GET /','home'); function home() { echo 'Hello, world!'; } F3::run(); But when I try to add in the second part, which has two routes: require_once 'F3/F3.php'; F3::route('GET /','home'); function home() { echo 'Hello, world!'; } F3::route('GET /about','about'); function about() { echo 'About Us.'; } F3::run(); I get a 404 error if I try the second URL: /about Not sure why one of the mod_rewrite commands would be working and not the other. Below is my .htaccess file: # Enable rewrite engine and route requests to framework RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-l RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule .* index.php [L,QSA] # Disable ETags Header Unset ETag FileETag none # Default expires header if none specified (stay in browser cache for 7 days) <IfModule mod_expires.c> ExpiresActive On ExpiresDefault A604800 </IfModule>

  • autocomplete: how do I avoid a duplicate search?

    - by dnagirl
    I use JQuery plugin autocomplete as a kind of dataset chooser. If the user chooses a value from the autocomplete lookup, the database is queried for the matching dataset. If the user types in a new value, the user can enter a new dataset. An issue arises when the user types in an existing value rather than choosing it from the autocomplete lookup. When this is done, the autocomplete .result() method is not called and no dataset is retrieved. To fix this I added a .blur(function(){$(this).search();}); to the input element. This fixed the original problem. Now I have the problem that .result() fires on selection from lookup AND on blur. I would like .result() to fire on selection from lookup OR on blur. How do I make that happen? Here is my code: $('#groupset').autocomplete('ajax/php/leeruns.php'); $('#groupset').result( function(event, data, formatted) { if(data){ $('#groupsetdesc').val(formatted); groups.load(data[1]); //retrieve matching dataset } else { $('#groupsetdesc').val(''); } } ).blur(function(){$(this).search();});

  • Multiple marker icons, how to add to google mashup

    - by user351189
    I have created a Google maps mashup, where with a bit of input, I have managed to have a sidebar that links to a video icon/marker that then opens up an info window showing virtual tours. I would, however, like to put different coloured marker icons on the map depending on the category that the video is in. This would be easy enough to do, but my page is made up of a mixture of J-Query and JavaScript all calling to the individual flash files. Could someone help me with the code for adding extra marker icons for different categories? Here is the code: So, after the intial 'var camera;' point, there comes this: function addMarker(point, title, video, details) { var marker = new GMarker(point, {title: title, icon:camera}); GEvent.addListener(marker, "click", function() { if (details) { marker.openInfoWindowTabsHtml([new GInfoWindowTab("Video", video), new GInfoWindowTab("More", details)]); } else { marker.openInfoWindowHtml(video); } }); Then further down, is the code for calling the individual marker image. I would like to add another image to this list - would I start out by calling the new object 'camera-red.image' or something similar? function initialize() { if (GBrowserIsCompatible()) { map = new GMap2(document.getElementById("mapDiv")); map.setCenter(new GLatLng(51.52484592590448, -0.13345599174499512), 17); map.setUIToDefault(); var uclvtSatMapType = createUclVTSatMapType() map.addMapType(uclvtSatMapType); map.setMapType(uclvtSatMapType); camera = new GIcon(G_DEFAULT_ICON); camera.image = "ucl-video.png"; camera.iconSize = new GSize(32,37); camera.iconAnchor = new GPoint(16,35); camera.infoWindowAnchor = new GPoint(16,2); addMarkersToMap(); } The actual map can be found here: link text Thanks.

  • WCF - "Encountered unexpected character 'c'."

    - by Villager
    Hello, I am trying to do something that I thought would be simple. I need to create a WCF service that I can post to via JQuery. I have an operation in my WCF service that is defined as follows: [OperationContract] [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedRequest, RequestFormat=WebMessageFormat.Json, ResponseFormat=WebMessageFormat.Json)] public string SendMessage(string message, int urgency) { try { // Do stuff return "1"; // 1 represents success } catch (Exception) { return "0"; } } I then try to access this operation from an ASP.NET page via JQuery. My JQuery code to access this operation looks like the following: function sendMessage(message) { $.ajax({ url: "/resources/services/myService.svc/SendMessage", type: "POST", contentType: "application/json; charset=utf-8", data: ({ message: message, urgency: '1' }), dataType: "json", success: function (data) { alert("here!"); }, error: function (req, msg, obj) { alert("error: " + req.responseText); } }); } When I execute this script, the error handler is tripped. In it, I receive an error that says: "Encountered unexpected character 'c'." This message is included with a long stack trace. My question is, what am I doing wrong? I have received other posts such as this one (http://stackoverflow.com/questions/320291/how-to-post-an-array-of-complex-objects-with-json-jquery-to-asp-net-mvc-controll) without any luck. How do I get this basic interaction working? Thank you!

  • Are there any security issues to avoid when providing a either-email-or-username-can-act-as-username

    - by Tchalvak
    I am in the process of moving from a "username/password" system to one that uses email for login. I don't think that there's any horrible problem with allowing either email or username for login, and I remember seeing sites that I consider somewhat respectable doing it as well, but I'd like to be aware of any major security flaws that I may be introducing. More specifically, here is the pertinent function (the query_row function parameterizes the sql). function authenticate($p_user, $p_pass) { $user = (string)$p_user; $pass = (string)$p_pass; $returnValue = false; if ($user != '' && $pass != '') { // Allow login via username or email. $sql = "SELECT account_id, account_identity, uname, player_id FROM accounts join account_players on account_id=_account_id join players on player_id = _player_id WHERE lower(account_identity) = lower(:login) OR lower(uname) = lower(:login) AND phash = crypt(:pass, phash)"; $returnValue = query_row($sql, array(':login'=>$user, ':pass'=>$pass)); } return $returnValue; } Notably, I have added the WHERE lower(account_identity) = lower(:login) OR lower(uname) = lower(:login) ...etc section to allow graceful backwards compatibility for users who won't be used to using their email for the login procedure. I'm not completely sure that that OR is safe, though. Are there some ways that I should tighten the security of the php code above?

  • Can't access dynamically generated div with Jquery

    - by Bug Magnet
    Still trying to get my head around JQuery and dynamically generated content. I have the following code that is dynamically generated with JQuery whenever a user clicks on an 'Add' button: <div id="practices_div" style="border-top: 1px dotted gray"> <br/> <a href="#" class="remove_link" rel="practices_div">Remove</a> ....content goes here </div> The JQuery code that dynamically loads the above content is as follows: $.ajax({ url: '/addAjax.html', success: function(response) { $('#container').append(response); } }); What I'm trying to do is when a user clicks on the Remove link, JQuery should hide and delete the dynamically generated content from the page. The code that does this is as follows: $('.remove_link').live('click', function() { if (confirm("Remove this item?")) { $('#practices_div').fadeOut('medium', function() { $(this).remove(); }); } return false; }); So, when the content is dynamically loaded via Ajax, and I click on the Remove link, the Confirmation dialogue box is displayed and if I confirm, nothing happens. For some reason, JQuery is not able find the dynamically generated #practices_div. Any idea what I may be doing wrong?

  • Segmentation fault on certain inputs and not others

    - by Brandon Schwandt
    Heres a function I wrote that has some debugging elements in it already. When i enter either a "y" or a "Y" as the input I get a segmentation fault during runtime. When I enter any other value the code runs. The seg fault kicks out after it scans and gives me the response but before the "scan worked" line is output. DOn't know why it would act like this only on these values. If anyone needs the function call I have that as well. query_user(char *response [10]) { printf("response after query call before clear=%s\n",response); strcpy(response,""); printf("response after clearing before scan=%s\n",response); printf("Enter another person into the line? y or n\n"); scanf("%s", response); printf("response after scan=%s\n",response); printf("scan worked"); } main() { char response [10]; strcpy(response,"y"); printf("response=%s\n",response); printf("When finished with program type \"done\" to exit\n"); while (strcmp(response,"done") != 0) { printf("response after while loop and before query call=%s\n",response); query_user(&response); } } output on error: response after query call before clear=y response after clearing before scan= Enter another person into the line? y or n y response after scan=y Segmentation Fault (core dumped) output on non-error: response after query call before clear=y response after clearing before scan= Enter another person into the line? y or n n response after scan=n scan worked Cycle number 0 (program continues to run outside this function)

  • Chrome extension javascript array bug?

    - by Wayne Werner
    Hi, I'm working on a Google Chrome extension. In the popup I have the following code: var bookmarks = []; function appendBMTnode(node){ bookmarks.push([node[0].title, node[0].id]); } function addchildren(results){ for(x = 0; x < results.length; x++){ bookmarks.push([results[x].title, results[x].id]); chrome.bookmarks.getChildren(results[x].id, addchildren); } } function getallbookmarks(){ chrome.bookmarks.get('0', appendBMTnode); chrome.bookmarks.getChildren('0', addchildren); } console.debug(bookmarks.length); console.debug(bookmarks); Now, I would assume that the first command would issue the # of bookmarks I have. Indeed, when I use Chrome's debugger and add bookmarks.length to the watch list, 418 is the value. In the console of the debugger I can write bookmarks.length and it will give me the correct length. I can type for(x = 0; x < bookmarks.length; x++){ console.debug(bookmarks[x]); } and I get string representations of each inner array. However, that original console.debug(bookmarks.length) gives an output of zero. And if I add console.debug(bookmarks[0]); to the popup.html it tells me that the value is undefined. This seems like a bug to me, but my real question is how can I iterate over this list? Thanks

  • jQuery password strength plugin callback validation method

    - by jmorhardt
    I'm using a a jQuery plugin to evaluate password strength. It gives a graphical representation for the user to see how secure the password is. I'd like to use it to validate the field as well. The plugin works by assessing the password and giving it a score. I want to be able to verify that the user has entered a password of at least a certain score. The code is hosted on jQuery's site here: http://plugins.jquery.com/project/pstrength. The documentation states that there is a way to add a rule and do custom validation. I'm not sure where to start. The inline documentation states: * === Changelog === * Version 2.1 (18/05/2008) * Added a jQuery method to add a new rule: jQuery('input[@type=password]').pstrength.addRule(name, method, score, active) And later in the code there's this method: jQuery.extend(jQuery.fn.pstrength, { 'addRule': function (name, method, score, active) { digitalspaghetti.password.addRule(name, method, score, active); return true; }, 'changeScore': function (rule, score) { digitalspaghetti.password.ruleScores[rule] = score; return true; }, 'ruleActive': function (rule, active) { digitalspaghetti.password.rules[rule] = active; return true; } }); If anybody has seen an example of how to do this I'd appreciate a pointer in the right direction. Thanks!

  • addEventListener pass caller as argument

  • Broken JS Loop with Google Maps...

    - by Oscar Godson
    My code is below, and I had an issue with nearly the same code, and it was fixed here on StackOverflow, but, again, its not working. I haven't changed the working code, but i did wrap it in the for...in loop youll see below. The issue is that no matter what marker I click it always triggers the last marker/infoWindow that was placed. $(function(){ var latlng = new google.maps.LatLng(45.522015,-122.683811); var settings = { zoom: 10, center: latlng, disableDefaultUI:true, mapTypeId: google.maps.MapTypeId.SATELLITE }; var map = new google.maps.Map(document.getElementById("map_canvas"), settings); $.getJSON('api',function(json){ for (var property in json) { if (json.hasOwnProperty(property)) { var json_data = json[property]; var the_marker = new google.maps.Marker({ title:json_data.item.headline, map:map, clickable:true, position:new google.maps.LatLng( parseFloat(json_data.item.geoarray[0].latitude), parseFloat(json_data.item.geoarray[0].longitude) ) }); var infowindow = new google.maps.InfoWindow({ content: '<div><h1>'+json_data.item.headline+'</h1><p>'+json_data.item.full_content+'</p></div>' }); new google.maps.event.addListener(the_marker, 'click', function() { infowindow.open(map,the_marker); }); } } }); }); Thank you for whoever figures this out!

  • Modify columns in a data frame in R more cleanly - maybe using with() or apply()?

    - by Mittenchops
    I understand the answer in R to repetitive things is usually "apply()" rather than loop. Is there a better R-design pattern for a nasty bit of code I create frequently? So, pulling tabular data from HTML, I usually need to change the data type, and end up running something like this, to convert the first column to date format (from decimal), and columns 2-4 from character strings with comma thousand separators like "2,400,000" to numeric "2400000." X[,1] <- decYY2YY(as.numeric(X[,1])) X[,2] <- as.numeric(gsub(",", "", X[,2])) X[,3] <- as.numeric(gsub(",", "", X[,3])) X[,4] <- as.numeric(gsub(",", "", X[,4])) I don't like that I have X[,number] repeated on both the left and ride sides here, or that I have basically the same statement repeated for 2-4. Is there a very R-style way of making X[,2] less repetitive but still loop-free? Something that sort of says "apply this to columns 2,3,4---a function that reassigns the current column to a modified version in place?" I don't want to create a whole, repeatable cleaning function, really, just a quick anonymous function that does this with less repetition.

  • Uploading multiple files asynchronously by blueimp jquery-fileupload

    I'm using jQuery File Upload library (http://github.com/blueimp/jQuery-File-Upload), and I've been stuck figuring out how to use the library satisfying the following conditions. The page has multiple file input fields surrounded by a form tag. Users can attach multiple files to each input field All files are sent to a server when the button is clicked, not when files are attached to the input fields. Upload is done asynchronously Say the page has 3 input fields with their name attributes being "file1[]", "file2[]" and "file3[]", the request payload should be like {file1: [ array of files on file1[] ], file2: [ array of files on file2[] ], ...} Here's jsFiddle, it's behaving weird so far in that it sends post request twice and the first one is cancelled. http://jsfiddle.net/BAQtG/24/ The core part of js code looks like this. $(document).ready(function(){ var filesList = [] var elem = $("form") file_upload = elem.fileupload({ formData:{extra:1}, autoUpload: false, fileInput: $("input:file"), }).on("fileuploadadd", function(e, data){ filesList.push(data.files[0]) }); $("button").click(function(){ file_upload.fileupload('send', {files:filesList} ) }) }) Anybody have idea how to get this to work? Updates Now thanks to @CBroe 's comment, the issue that request is sent twice is fixed. However the keys of request parameter is not correctly set. Here's updated jsFiddle. http://jsfiddle.net/BAQtG/27/

  • JS: Object itteration fails

    - by Newbie
    Hello! In my JS, I have an object called box_object. It looks like this: ({ id:"3", text:"this is a box object", connection_parent:["1", "2"], connection_child:["5", "6"], connectiondata_child:{ 0:{id:"5", linepoint:"bottom"}, 1:{id:"6", linepoint:"bottom"}}, connectiondata_parent:{ 0:{id:"1", linepoint:"top"}, 1:{id:"2", linepoint:"top"}} }) Now, I want to add some position values to box_object.connectiondata_parent. Using jQuery I can use the .each() method. So I tried it, but it failed. In my function I do the following: $(box_object.connectiondata_parent).each(function(it, obj){ if(typeof(obj[it]) != "undefined" && obj[it].linepoint == "top"){ var point_position_top = new Object(); point_position_top.left = startingpoint_left; point_position_top.top = startingpoint_top; obj[it].position = point_position_top; }else if(typeof(obj[it]) != "undefined" && obj[it].linepoint == "bottom"){ var point_position_bottom = new Object(); point_position_bottom.left = startingpoint_left; point_position_bottom.top = startingpoint_bottom; obj[it].position = point_position_bottom; }else{} }); After the function my box_object looks like this: ({ id:"3", text:"this is third box", connection_parent:["1", "2"], connection_child:["5", "6"], connectiondata_child:{ 0:{id:"5", linepoint:"bottom"}, 1:{id:"6", linepoint:"bottom"}}, connectiondata_parent:{ 0:{id:"1", linepoint:"top", position:{left:500, top:104}}, 1:{id:"2", linepoint:"top"}} }) It seems it only writes the values to the first "value". Any Ideas why?
