  • JQuery, Load() contents with plugins

    - by Galas
    I know this is not a completely new question, but none of the answers solved my problem... I have built a little menu that uses load() to load image galleries (as external html files) into a specified div ("content"). The said galleries make use of a JQuery plugin (SlideJS). Now I know that load() does not work for script tags and that I need to use $.getscript in the callback function in order to run the scripts, but it does not work. I have two .js files that need to be loaded: one is the plugin itself and another one is a smaller script with a preloader and the animations for the captions. I can't seem to merge them together; if I put them into the same document, the script won't run. So I tried just using $.getscript to load the two files. I tried using two callbacks as suggested in other answer (I know it's not ideal...): $("#proposal").click(function(){ $(this).addClass('selected'); $("a:not(:#proposal)").removeClass('selected'); $("#content").load("works/proposal/proposal.html", function(){ $.getScript("js/slide.js", function (){ $.getScript("js/slidepage.js"); }); }); }); and I tried a variable (read about it in some other faq, not sure if the syntax is correct) $("#proposal").click(function(){ $(this).addClass('selected'); $("a:not(:#proposal)").removeClass('selected'); $("#content").load("works/proposal/proposal.html", function(){ var scripts = ['js/slide.js','js/slidepage.js']; $.getScript(scripts); }); }); So none of these work. What am I doing wrong? I'm just starting on jquery and my js knowledge is very limited. Should I just merge the two .js files together using minify or something? One of them is already minified, but I've tried with a non-minified version and it does not work either. Can anyone suggest any other solution around this problem? I thought of just having the div embedded in the main document and just showing it on click, but I'll have at least 4 galleries with about 8 to 10 images each... its a lot of images to load in the main page, so I don't think its the best way. if you need me to post any more code, please ask! Thanks in advance for all your help!

  • How do you make the script wait for the status of an Ajax get request before continuing?

    - by codeninja
    Basically what I'm doing is checking for the existence of an object, if it's not found, the script will try to load the source file using getScript. I only want to check this once though then return true or false to the function that calls fetch() fetch:function(obj){ ... isReady = false; $.getScript(obj.srcFile,function(){ isReady=true; warn("was able to load object "+key); }); return isReady; } but return kicks in before the script loads =/ later the script is loaded but the function returned false. This is the beauty of asynchronous I suppose... What's the best way to handle this... Maybe I could check again at some other point if the object exists? Or maybe there's a better way to do this where I dont have to potentially lock the browser?

  • Responsive: two different toggles on same element

    - by Mathijs Delva
    I'm having difficulties with the following problem. For a responsive website, i need to use the same toggle element for both a toggle system for one window width, and another toggle system for a second window width. I have the following snippets: 1.A simple hover for a language dropdown, which should be executed for resolutions greater than 980px. $('#clickme').hover(function() { $(this).parent().find("#select-language").show(); $(this).find("> a span").css({"opacity":"0.5"}); }, function() { $(this).parent().find("#select-language").hide(); $(this).find("> a span").css({"opacity":"1"}); }); 2.A simple click for the same language toggle, which should be executed for resolutions smaller than 980px. jQuery('#clickme').click(function() { jQuery("#select-language-mobile").slideToggle("fast"); }); I need to nest these two, so that when the user is viewing the website in one resolution, the click function with be fired, and in the other case the hover function. Can anybody help me with this? PS: I'm sorry, but the code blocks don't seem to work at the moment.

  • lightbox dynamic image retrieval

    - by GSTAR
    I am constructing a lighbox gallery, currently experimenting with FancyBox (http://fancybox.net) and ColorBox (http://colorpowered.com/colorbox). By default you have to include a link to the large version of the image so that the Lightbox can display it. However, I am wanting to have the image link URLs pointing to a script rather than directly to the image file. So for example, instead of: <a href="mysite/images/myimage.jpg"> I want to do: <a href="mysite/photos/view/abc123"> The above URL points to a function: public function actionPhotos($view) { $photo=Photo::model()->find('name=:name', array(':name'=>$view)); if(!empty($photo)) { $user=$photo->user; $this->renderPartial('_photo', array('user'=>$user, 'photo'=>$photo, true)); } } At some point in the future the function will also update the view count of the image. Now this approach is working to an extent - most images load up but some do not load up (the lightbox gets displayed in a malformed state). I think the reason for this is because it is not processing the function quick enough. For example when I click the "next" button it needs to go to the URL, process the function and retreive/output the response. Does anybody know how I can get this working properly?

  • How to convert a string to variable name

    - by p1xelarchitect
    I'm loading several external JSON files and want to check if they have been successfully cached before the the next screen is displayed. My strategy is to check the name of the array to see if it an object. My code works perfectly when I check only a single array and hard code the array name into my function. My question is: how can i make this dynamic? not dynamic: (this works) $("document").ready(){ checkJSON("nav_items"); } function checkJSON(){ if(typeof nav_items == "object"){ // success... } } dynamic: (this doesn't work) $("document").ready(){ checkJSON("nav_items"); checkJSON("foo_items"); checkJSON("bar_items"); } function checkJSON(item){ if(typeof item == "object"){ // success... } } here is the a larger context of my code: var loadAttempts = 0; var reloadTimer = false; $("document").ready(){ checkJSON("nav_items"); } function checkJSON(item){ loadAttempts++; //if nav_items exists if(typeof nav_items == "object"){ //if a timer is running, kill it if(reloadTimer != false){ clearInterval(reloadTimer); reloadTimer = false; } console.log("found!!"); console.log(nav_items[1]); loadAttempts = 0; //reset // load next screen.... } //if nav_items does not yet exist, try 5 times, then give up! else { //set a timer if(reloadTimer == false){ reloadTimer = setInterval(function(){checkJSON(nav_items)},300); console.log(item + " not found. Attempts: " + loadAttempts ); } else { if(loadAttempts <= 5){ console.log(item + " not found. Attempts: " + loadAttempts ); } else { clearInterval(reloadTimer); reloadTimer = false; console.log("Giving up on " + item + "!!"); } } } }

  • How do call this symbolic code transformation ?

    - by erric
    Hi, I often cross this kind of code transformation (or even mathematical transformation) (python example, but applies to any language) I've go a function def f(x): return x I use it into another one. def g(x): return f(x)*f(x) print g(2) leads to 4 But I want to remove the functional dependency, and I change the function g into def g(f): return f*f print g( f(2) ) leads to 4 too How do you call this kind of transformation, locally turning a function into a scalar ?

  • Javascript Global Variable in Array

    - by user1387727
    My question may be very easy to lots of people, but I am new to Javascript. I really do not know what is wrong with the following codes. var newValue = 1; function getCurrentAmount() { return [newValue,2,3]; } var result = getCurrentAmount(); console.log(result[0] + "" + result[1] + result[2]); In the above code, the result shown in console is: undefined23 Why is the result not "123"? I am trying to use global variable because I want to increment newValue by 1 each time when the function is called. I want something like the following: var newValue = 1; function getCurrentAmount() { newValue ++; return [newValue,2,3]; } setInterval(function(){ var result = getCurrentAmount(); console.log(result[0] + "" + result[1] + result[2]); }, 1000); Also, I just tired the following codes and it works as expected. var newValue =1; function test() { newValue ++; return newValue; } console.log(test()); So I think the problem is about the Array. I hope my question is clear enough. Thanks in advance.

  • IE8 error when using dyanamic form actions

    - by user330711
    Hello all: Please go here to see an iframe based web app. Click on the map of Australia, choose a city, then buy some tickets. Now you will see the cart form located on the lower right corner. The problem is in IE8, I cannot delete checked rows from the table; whereas in other browsers such as FireFox3.6, Opera10, Safari4 and Chrome4, this action is all right. Below is the related javascript. It doesn't use jQuery, as part of the requirement is no framework allowed! And iframes are the my best bet, ajax will simply kill me under this restriction. /* cartForm.js */ function toDeleteRoutes() //this function is executed before form is to be submitted. { if(document.getElementsByClassName('delete_box').length > 0) //there're rows to delete { document.getElementById('cartForm').action ="./deleteRoutes.php"; document.getElementById('cartForm').target ="section4"; return true; //this enables the form to be submitted as usual. } else return false; //there is no more row in table to delete! } function toSendEmail() //this function is executed before form is to be submitted. { document.getElementById('cartForm').action ="./sendEmail.php"; document.getElementById('cartForm').target ="section3"; document.getElementById('delete_btn').disabled = true; //disable delete button now return true; //this enables the form to be submitted as usual. } function toCancelPurchase() { document.getElementById('cartForm').action ="./cancelPurchase.php"; document.getElementById('cartForm').target ="section4"; return true; //this enables the form to be submitted as usual. } I don't know which part is wrong, or this is just because IE8 screws all?

    var blah = Some.Thing(data, function(a,b) { // code here }); Some.Thing = function(data, callback) { var a = Other.Thing(data, function() { }); }; My question is, will the part that says //code here fire ONLY after everything else and their callbacks fire? The //code here part seems to fire, and there seems to be some timing issue.

  • Should I use "User Defined Functions" in SQL server, or C#?

    - by sanity
    I have a fairly complicated mathematical function that I've been advised should be implemented as a User Defined Function in SQL Server so that it can be used efficiently from within a SQL query. The problem is that it must be very efficient as it may be executed thousands of times per second, and I subsequently heard that UDFs are very inefficient. Someone suggested that I could implement the function in C# instead, and that this would be much more efficient. What should I do?

  • FineUploader multiple instances and dynamic naming

    - by RichieMN
    I am using FineUploader 4.0.8 within a MVC4 project using the jquery wrapper. Here is an example of my js code that creates a single instance of the fineUploader and is working just fine. At this time, I have the need for more than one instance of fineUploader, but each individual control doesn't know anything about the other and they're rendered as needed on a page (I've seen previous questions using a jQuery .each, which won't work here). Currently, I can't seem to correctly render any upload buttons, probably due to having an ID duplicated or something. See below for how I'm using MVC's Razor to create unique variables and html IDs for that individual instance. Here's my current implementation where I've added the dynamic values (places where you see _@Model.{PropertyName}): // Uploader control setup var [email protected] = $('#[email protected]').fineUploader({ debug: true, template: '[email protected]', button: $("#[email protected]"), request: { endpoint: '@Url.Action("UploadFile", "Survey")', customHeaders: { Accept: 'application/json' }, params: { [email protected]: (function () { return instance; }), [email protected]: (function () { return surveyItemResultId; }), [email protected]: (function () { return itemId; }), [email protected]: (function () { return loopingCounter++; }) } }, validation: { acceptFiles: ['image/*', 'application/xls', 'application/pdf', 'text/csv', 'application/vnd.openxmlformats-officedocument.spreadsheetml.template', 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet', 'application/vnd.ms-excel'], allowedExtensions: ['jpeg', 'jpg', 'gif', 'png', 'bmp', 'csv', 'xls', 'xlsx', 'pdf', 'xlt', 'xltx', 'txt'], sizeLimit: 1024 * 1024 * 2.5, // 2.5MB stopOnFirstInvalidFile: false }, failedUploadTextDisplay: { mode: 'custom' }, multiple: true, text: { uploadButton: 'Select your upload file(s)' } }).on('submitted', function (event, id, filename) { $("#modal-overlay").fadeIn(); $("#modal-box").fadeIn(); [email protected]++; $(':input[type=button], :input[type=submit], :input[type=reset]').attr('disabled', 'disabled'); }).on('complete', function (event, id, filename, responseJSON) { [email protected]++; if ([email protected] == [email protected]) { $(':input[type=button], :input[type=submit], :input[type=reset]').removeAttr('disabled'); //$("#overlay").fadeOut(); $("#modal-box").fadeOut(); $("#modal-overlay").fadeOut(); } }).on('error', function (event, id, name, errorReason, xhr) { //$("#overlay").fadeOut(); alert('error: ' + errorReason); $("#modal-box").fadeOut(); $("#modal-overlay").fadeOut(); }); }); Using the same principle as above, I've added this logic to the template too. Here's part of my template: <script type="text/template" id="[email protected]"> <div class="qq-uploader-selector qq-uploader"> <div class="qq-upload-drop-area-selector qq-upload-drop-area qq-hide-dropzone"> <span>Drop files here to upload</span> What I see when I use the above code is only the drag and drop section visible, and no button. There are no js errors either. I do have an example that only has one instance of this control on it and the results are the same visible drag and drop section and no button). Any thought as to what's going on? I'll gladly update the question if you find I'm missing something helpful. Please don't just -1 me if it's something I can easily improve or fix.

  • Array length is zero in jQuery.

  • What is the correct way to fix this Javascript closure

    - by sujoe
    I have been familiarizing myself with javascript closures and ran across this article http://blog.morrisjohns.com/javascript_closures_for_dummies.html Due to the closure, Example 5 does not work as expected. How would one modify result.push( function() {alert(item + ' ' + list[i])} ); to make the code work? function buildList(list) { var result = []; for (var i = 0; i < list.length; i++) { var item = 'item' + list[i]; result.push( function() {alert(item + ' ' + list[i])} ); } return result; } function testList() { var fnlist = buildList([1,2,3]); // using j only to help prevent confusion - could use i for (var j = 0; j < fnlist.length; j++) { fnlist[j](); } } testList(); Thanks!

  • Encoding GBK2312 Condundrum

    - by user792271
    I am an amateur coder and I have a small problem. My goal is to have one text input with two buttons. The first button uses a bit of Javascript called SundayMorning to translate the text (to Chinese) The second button submits the text to a URL. The URl requires that Chinese text be encoded it in GBK2312 character set. I have duct taped together various found code to the result I have now. Due to the finicky behavior of the SundayMorning Javascript, my solution is to have two input boxes, the second of which I will hide. Right now, this doesn't work: I am unable to encode the Chinese in GBK2312, no matter what I try. BONUS CONUNDRUM: The second box copies my input letter by letter as I type, but does not copy the Chinese translation that the Javascript returns. Sorry for my janky amateur code. I defer to those more clever, if you have any kind suggestions. <head> <meta http-equiv="Content-Type" content="text/html; charset=GB2312" /> <script type='text/javascript' Src='https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js'> </script> ///THIS JS TRANSLATES THE TEXT INLINE <script type="text/javascript" src="jquery.sundaymorning.js"> </script> <script type="text/javascript"> $(function() { $('#example3').sundayMorningReset(); $('#example3 input[type=image]').click(function(evt) { $.sundayMorning( $('#example3 input[type=text]').val(),{source:'en', destination:'ZH', menuLeft:evt.pageX, menuTop:evt.pageY},function(response) {$('#example3 input[type=text]').val(response.translation);});});}); </script> /// ///THIS PUTS THE CONTENT OF THE TRANSLATION BOX INTO THE SUBMISSION BOX <script type="text/javascript"> $(document).ready(function(){ var $url = $("#url"); $("#track").keyup(function() { $url.val(this.value);}); $("#track").blur(function() { $url.val(this.value);});}); </script> ///THIS PUTS THE CONTENT OF THE SUBMISSION INSIDE A URL <SCRIPT type="text/javascript"> function goToPage(url) { var initial = "http://example.com/"; var extension = ".html"; document.something.action=initial+url+extension; } </SCRIPT> </head> <body> <div id="featured"> <div id="example3"> <input type="text" name="track" id="track" value="" class="box"onkeydown="javascript:if (event.which || event.keyCode){if ((event.which == 13) || (event.keyCode == 13)) {document.getElementById('mama').click();}};"/> <input type="image" src="http://taobaofieldguide.com/images/orange-translate-button.png" id="searchsubmit" value="Translate" class="btn" /> </div> <FORM name="something" method="post" onsubmit="goToPage(this.url.value);"> <input type="text" id="url";> <INPUT type="submit" id="mama" value="GO" > </FORM> </div> </body>

  • Dynamic jQuery dialog after data append w/o reloading page. Possible?

    - by Arun
    Howdy, So I have a page with an enormous table in a CRUD interface of sorts. Each link within a span calls a jQuery UI Dialog Form which fetches it's content from another page. When the action taking place (in this case, a creation) has completed, it appends the resulting new data to the table and forces a resort of the table. This all happens within the JS and the DOM. The problem with this, is that the new table row's CRUD links don't actually trigger the dialog form creation as all the original links in spans are only scanned on document.ready and since I'm not reloading the page, the new links cannot be seen. Code is as follows: $(document).ready(function() { var $loading = $('<img src="/images/loading.gif" alt="Loading">'); $('span a').each(function() { var $dialog = $('<div></div>') .append($loading.clone()); var $link = $(this).one('click', function() { // Dialog Stuff success: function(data) { $('#studies tbody').append( '<tr>' + '<td><span><a href="./?action=update&study=' + data.study_id + '" title="Update Study">Update</a></span></td>' + '</tr>' ); fdTableSort.init(#studies); // This re-sorts the table. $(this).dialog('close'); } $link.click(function() { $dialog.dialog('open'); return false; }); return false; }); }); }); Basically, my question is if there is any way in which to trigger a jQuery re-evaluation of the pages links without forcing me to do a browser page refresh?

  • PHP - How do you secure a unique variable name?

    - by 102319141763223461745
    This function cropit, which I shamelessly stole off the internet, crops a 90x60 area from an existing image. In this code, when I use the function for more than one item (image) the one will display on top of the other (they come to occupy the same output space). I think this is because the function has the same (static) name ($dest) for the destination of the image when it's created (imagecopy). I tried, as you can see to include a second argument to the cropit function which would serve as the "name" of the $dest variable, but it didn't work. In the interest of full disclosure I have 22 hours of PHP experience (incidentally the same number of hours since the last I slept) and I am not that smart to begin with. Even if there's something else at work here entirely, seems to me that generally it must be useful to have a way to secure that a variable is always given a unique name. function cropit($srcimg, $dest) { $im = imagecreatefromjpeg($srcimg); $img_width = imagesx($im); $img_height = imagesy($im); $width = 90; $height = 60; $tlx = floor($img_width / 2) - floor ($width / 2); $tly = floor($img_height / 2) - floor ($height / 2); if ($tlx < 0) { $tlx = 0; } if ($tly < 0) { $tly = 0; } if (($img_width - $tlx) < $width) { $width = $img_width - $tlx; } if (($img_height - $tly) < $height) { $height = $img_height - $tly; } $dest = imagecreatetruecolor ($width, $height); imagecopy($dest, $im, 0, 0, $tlx, $tly, $width, $height); imagejpeg($dest); imagedestroy($dest); } $img = "imagefolder\imageone.jpg"; $img2 = "imagefolder\imagetwo.jpg"; cropit($img, $i1); cropit($img2, $i2); ?

  • jQuery: Any way to "refresh" event handlers?

    - by Legend
    I have two divs, one that holds some stuff and the other with all possible stuff. Clicking on one of the divs will transfer items to the other div. The code I came up with is: $("#holder > *").each(function() { $(this).click(function(e) { $(this).remove(); $("#bucket").append(this); }); }); $("#bucket > *").each(function() { $(this).click(function(e) { $(this).remove(); $("#holder").append(this); }); }); This one works perfectly, except that the event handlers need to be refreshed once I append or remove elements. What I mean is, if I first click on an element, it gets added to the other div, but if I click on this element again, nothing happens. I can do this manually but is there a better way to achieve this?

  • Trying to call JS Code that is passed back from AJAX call....

    - by Dutchie432
    Okay, so I have an javascript function that retrieves some HTML... function updateQuestions(i){ var url = 'getQuestions.php?sys=' + i; if (receiveReq.readyState == 4 || receiveReq.readyState == 0) { receiveReq.open("GET", url, true); receiveReq.onreadystatechange = handleQuestionsUpdate; receiveReq.send(null); } } function handleQuestionsUpdate() { if (receiveReq.readyState == 4) { var a=receiveReq.responseText; document.getElementById('questions').innerHTML=a; checkSpeakers(); //Error Occurs Here, even though checkSpeakers() is a function in the returned HTML chunk. } } This HTML is not just HTML, but it is more specifically a form and a chunk of javascript. The javascript is hard-coded into the HTML and not referenced by <script src=".."> Is it normal that this retrieved JS code isn't recognized upon call-time? If so, what is my alternative if I need the JS to change every time the div is update? Now
