  • How does jQuery store data with .data()?

    - by TK
    I am a little confused how jQuery stores data with .data() functions. Is this something called expando? Or is this using HTML5 Web Storage although I think this is very unlikely? The documentation says: The .data() method allows us to attach data of any type to DOM elements in a way that is safe from circular references and therefore from memory leaks. As I read about expando, it seems to have a rick of memory leak. Unfortunately my skills are not enough to read and understand jQuery code itself, but I want to know how jQuery stores such data by using data(). http://api.jquery.com/data/

  • Suppose i have an HTML table. How do I use JQuery events on this?

    - by alex
    <table> <tr class="myRow"><td class="col1"></td><td class="col2"></td></tr> <tr class="myRow"><td class="col1"></td><td class="col2"></td></tr> <tr class="myRow"><td class="col1"></td><td class="col2"></td></tr> <tr class="myRow"><td class="col1"></td><td class="col2"></td></tr> <tr class="myRow"><td class="col1"></td><td class="col2"></td></tr> </table> How do I make the appropriate col1 fill with the letters "ABC" when the user rollovers the row? And then disappear the "ABC" when the user moves the mouse away from that row? So far, I got this. I solved it. $(".ep").hover(function(){ $(this).find('td.playButtonCol').html('PLAY'); },function(){ $(this).find('td.playButtonCol').html(''); });

  • Most efficient way to save tile data of an isometric game

    - by Harmen
    Hello, I'm working on an isometric game for fast browsers that support <canvas>, which is great fun. To save information of each tile, I use a two-dimensional array which contains numbers representing a tile ID, like: var level = [[1, 1, 1, 2, 1, 0], [0, 1, 1, 2, 0, 1], [0, 1, 1, 2, 1, 1]]; var tiles = [ {name: 'grass', color: 'green'}, {name: 'water', color: 'blue'}, {name: 'forest', color: 'ForestGreen'} ]; So far it works great, but now I want to work with heights and slopes like in this picture: For each tile I need to save it's tile ID, height and information about which corners are turned upward. I came up with a simple idea about a bitwise representation of all four corners, like this: 1011 // top, bottom and left corner turned up My question is: what is the most efficient way to save these three values for each cell? Is it possible to save these three values as one integer?

  • Google Chart Number formatting

  • How to append a row to a TableViewSection in Titanium?

    - by Mike Trpcic
    I'm developing an iPhone application in Titanium, and need to append a row to a particular TableViewSection. I can't do this on page load, as it's done dynamically by the user throughout the lifecycle of the application. The documentation says that the TableViewSection has an add method which takes two arguments, but I can't make it work. Here's my existing code: for(var i = 0; i <= product_count; i++){ productsTableViewSection.add( Ti.UI.createTableViewRow({ title:'Testing...' }) ); } That is just passing one argument in, and that causes Titanium to die with an uncaught exception: 2010-04-26 16:57:18.056 MyApplication[72765:207] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 2. The number of rows contained in an existing section after the update (2) must be equal to the number of rows contained in that section before the update (1), plus or minus the number of rows inserted or deleted from that section (0 inserted, 0 deleted).' 2010-04-26 16:57:18.056 MyApplication[72765:207] Stack: ( The exception looks like it did add the row, but it's not allowed to for some reason. Since the documentation says that TableViewSection takes in "view" and "row", I tried the following: for(var i = 0; i <= product_count; i++){ productsTableViewSection.add( Ti.UI.createView({}), Ti.UI.createTableViewRow({ title:'Testing...' }) ); } The above code doesn't throw the exception, but it gives a [WARN]: [WARN] Invalid type passed to function. expected: TiUIViewProxy, was: TiUITableViewRowProxy in -[TiUITableViewSectionProxy add:] (TiUITableViewSectionProxy.m:62) TableViewSections don't seem to support any methods like appendRow, or insertRow, so I don't know where else to go with this. I've looked through the KitchenSink app, but there are no examples that I could find of adding a row to a TableViewSection. Any help is appreciated.

  • AngularJS: download pdf file from the server

    - by Bartosz Bialecki
    I want to download a pdf file from the web server using $http. I use this code which works great, my file only is save as a html file, but when I open it it is opened as pdf but in the browser. I tested it on Chrome 36, Firefox 31 and Opera 23. This is my angularjs code (based on this code): UserService.downloadInvoice(hash).success(function (data, status, headers) { var filename, octetStreamMime = "application/octet-stream", contentType; // Get the headers headers = headers(); if (!filename) { filename = headers["x-filename"] || 'invoice.pdf'; } // Determine the content type from the header or default to "application/octet-stream" contentType = headers["content-type"] || octetStreamMime; if (navigator.msSaveBlob) { var blob = new Blob([data], { type: contentType }); navigator.msSaveBlob(blob, filename); } else { var urlCreator = window.URL || window.webkitURL || window.mozURL || window.msURL; if (urlCreator) { // Try to use a download link var link = document.createElement("a"); if ("download" in link) { // Prepare a blob URL var blob = new Blob([data], { type: contentType }); var url = urlCreator.createObjectURL(blob); $window.saveAs(blob, filename); return; link.setAttribute("href", url); link.setAttribute("download", filename); // Simulate clicking the download link var event = document.createEvent('MouseEvents'); event.initMouseEvent('click', true, true, window, 1, 0, 0, 0, 0, false, false, false, false, 0, null); link.dispatchEvent(event); } else { // Prepare a blob URL // Use application/octet-stream when using window.location to force download var blob = new Blob([data], { type: octetStreamMime }); var url = urlCreator.createObjectURL(blob); $window.location = url; } } } }).error(function (response) { $log.debug(response); }); On my server I use Laravel and this is my response: $headers = array( 'Content-Type' => $contentType, 'Content-Length' => strlen($data), 'Content-Disposition' => $contentDisposition ); return Response::make($data, 200, $headers); where $contentType is application/pdf and $contentDisposition is attachment; filename=" . basename($fileName) .

  • Rotate a feature Image in Open Layers

    - by Ozaki
    I have an open layers map. It adds and removes my "imageFeature" every 10secs or so. I have a JSON feed that gives me the rotation that I need, I have a request to get that rotation and set it as a variable of rotationv. Everything works but the fact when the image is recreated it does not update the rotation. My code is as follows: JSON request: var rotationv = (function () { rotationv = null; $.ajax({ 'async': false, 'global': true, 'url': urldefault, 'dataType': "json", 'success': function (data) { rotationv = data.rotation; } }); return rotationv })(); Creating image feature: imageFeature = new OpenLayers.Feature.Vector( new OpenLayers.Geometry.Point(mylon, mylat), { rotation: rotationv } ); The image is set in the styling elsewhere. Why does this not rotate my image?

  • Use queried json data in a function

    - by SztupY
    I have a code similar to this: $.ajax({ success: function(data) { text = ''; for (var i = 0; i< data.length; i++) { text = text + '<a href="#" id="Data_'+ i +'">' + data[i].Name + "</a><br />"; } $("#SomeId").html(text); for (var i = 0; i< data.length; i++) { $("#Data_"+i).click(function() { alert(data[i]); RunFunction(data[i]); return false; }); } } }); This gets an array of some data in json format, then iterates through this array generating a link for each entry. Now I want to add a function for each link that will run a function that does something with this data. The problem is that the data seems to be unavailable after the ajax success function is called (although I thought that they behave like closures). What is the best way to use the queried json data later on? (I think setting it as a global variable would do the job, but I want to avoid that, mainly because this ajax request might be called multiple times) Thanks.

  • Save jQuery callback functions in a separate file

    - by Danny Herran
    Probably I missed something, but lets say I have this: $('a.delete').click(function(){ resp=window.confirm("Are you sure you want to delete this?"); if(resp) return true; else return false; } Now, I want to save that callback function into a separate js file, because I will use it in several pages. My logic told me to do this: $('a.del').click(delete_element()); Having my js file like this: function delete_element(){ resp=window.confirm("Are you sure you want to delete this?"); if(resp) return true; else return false; } This doesn't work. Everytime my page loads, it displays the confirm window, even if I haven't clicked the link. It is clear that my logic failed this time. What am I missing?

  • How to post to a request using node.js

    - by Mr JSON
    I am trying to post some json to a URL. I saw various other questions about this on stackoverflow but none of them seemed to be clear or work. This is how far I got, I modified the example on the api docs: var http = require('http'); var google = http.createClient(80, 'server'); var request = google.request('POST', '/get_stuff', {'host': 'sever', 'content-type': 'application/json'}); request.write(JSON.stringify(some_json),encoding='utf8'); //possibly need to escape as well? request.end(); request.on('response', function (response) { console.log('STATUS: ' + response.statusCode); console.log('HEADERS: ' + JSON.stringify(response.headers)); response.setEncoding('utf8'); response.on('data', function (chunk) { console.log('BODY: ' + chunk); }); }); When I post this to the server I get an error telling me that it's not of the json format or that it's not utf8, which they should be. I tried to pull the request url but it is null. I am just starting with nodejs so please be nice.

  • Using Regex to modify a String

    - by Christine Dehner
    I have a String that looks like this: Blah blah one.<tmp>[[url=b, link=c]]</tmp> Blah blah two. Also remember, blah blah three.<tmp>[[url=d, link=e]]</tmp> So I want to get b and d (the url attribute of tmp), and change the String so that it looks like this (the ex() function returns a String): Blah blah one.<tmp>[[url=b, link=c, add=ex(b)]]</tmp> Blah blah two. Also remember, blah blah three.<tmp>[[url=d, link=e, add=ex(d)]]</tmp> I need to use regex because no existing library parses this type of markup. I hope my explanation is clear. Thanks in advance!

  • Understanding a skelton of jQuery plugin

    - by TK
    At a website, I found the following code to make a jQuery plugin: (function($){ // Our code here... })(jQuery); I don't understand how the code above works. What I understand is that the code executes immediately because the very last () in function(){}(). So the entire code says that is an anonymous function that is run immediately. But I don't understand why the wrapping needs to pass jQuery and that inside it needs $ to be passed. From my understanding, $ is an alias to jQuery, meaning practically the same. What is the meaning of $ and jQuery here? How does the overall code work as a jQuery plugin?

  • Exceptions thrown in jQuery AJAX callbacks swallowed?

    Is there any way to handle exceptions thrown from AJAX callbacks in jQuery, other than adding a try..catch block to each callback? The error function is not called in this situation. $.ajax( { url: 'myurl.rails', success: function( data ) { throw 'Oh no!'; }, error: function ( xhr, textStatus, errorThrown ) { console.log( 'AJAX call failed', xhr, textStatus, errorThrown ); } } );

  • Why should I reuse XmlHttpRequest objects?

    - by Xavi
    From what I understand, it's a best practice to reuse XmlHttpRequest objects whenever possible. Unfortunately, I'm having a hard time understanding why. It seems like trying to reuse XHR objects can increase code complexity, introduce possible browser incompatibilities, and lead to other subtle bugs. After researching this question for a while, I did come up with a list of possible explanations: Fewer objects created means less garbage collecting Reusing XHR objects reduces the chance of memory leaks The overhead of creating a new XHR object is high The browser is able to perform some sort of network optimization under hood But I'm not sure if any of these reasons are actually valid. Any light you can shed on this question would be much appreciated.

  • Back-to-back ajax long poll without a recursive callback function.

    - by Teddy
    I'm trying to make long poll ajax calls, back to back. The problem with the current way I'm doing it is that I make each successive call from the callback function of the previous call. Is this a problem? Firebug doesn't show any of my ajax calls as completed, even thought the data is returned and the callback is executed. The recursive structure seems inefficient. Any ideas?

  • WCF webHttpBinding with jQuery AJAX - removing/working around same origin policy

    - by csauve
    So I'm trying to create a C# WCF REST service that is called by jQuery. I've discovered that jQuery requires that AJAX calls are made under the same origin policy. I have a few questions for how I might proceed. I am already aware of; 1. The hacky solution of JSONP with a server callback 2. The way too much server overhead of having a cross-domain proxy. 3. Using Flash in the browser to make the call and setting up crossdomain.xml at my WCF server root. I'd rather not use these because; 1. I don't want to use JSON, or at least I don't want to be restricted to using it 2. I would like to separate the server that serves static pages from the one that serves application state. 3. Flash in this day in age is out of the question. What I'm thinking: is there anything like Flash's crossdomain.xml file that works for jQuery? Is this "same-origin" policy a part of jQuery or is it a restriction in specific browsers? If it's just a part of jQuery, maybe I'll try digging in the code to work around it.

  • iframe/lightbox refresh issues

    - by user96828
    Hi Please check out: http://gherkin.co.nz/refresh/ and click on the purple box that says 'Membership chest' You should then see some form fields in an iframe in the lightbox. If you click on the "GO" button, the page will change (currently Not found, which is fine for now). If you click the dark area to close the box, then click the purple card again - it will take you back to the not found page. When called, I want the content to always go back to the page specified in the iframe src, not the last page. Can it go back to the first specified page on this second click? Does that make sense? basically I want the iframe/lightbox to refresh its content each time it is called.
