  • GET Trello JSON to put in a string var

    - by Verber
    I'm trying to get the JSON that a TRELLO API Url returns and put it into a string. On my own private board I am getting "401 Unauthorized". But the Trello Api doesn't seem to give any way to authorize a user through the URL. If I try a public board I get "XMLHttpRequest cannot load https://api.trello.com/1/board/4d5ea62fd76aa1136000000c?key=68d02bf40d2ad57dd9eb418eb15f9564. Request header field X-Requested-With is not allowed by Access-Control-Allow-Headers." This is my code: <body> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js"> </script> <script> var list = $.getJSON(" https://api.trello.com/1/board/4d5ea62fd76aa1136000000c? key=68d02bf40d2ad57dd9eb418eb15f9564"); document.getElementById('print').innerHTML = list; </script> <div id="print"> </div> </body>

  • Checking data of all same class elements

    - by Tiffani
    I need the code to check the data-name value of all instances of .account-select. Right now it just checks the first .account-select element and not any subsequent ones. The function right now is on click of an element such as John Smith, it checks the data-name of the .account-select lis. If the data-names are the same, it does not create a new li with the John Smith data. If no data-names are equal to John Smith, then it adds an li with John Smith. This is the JS-Fiddle I made for it so you can see what I am referring to: http://jsfiddle.net/rsxavior/vDCNy/22/ Any help would be greatly appreciated. This is the Jquery Code I am using right now. $('.account').click(function () { var acc = $(this).data("name"); var sel = $('.account-select').data("name"); if (acc === sel) { } else { $('.account-hidden-li').append('<li class="account-select" data-name="'+ $(this).data("name") +'">' + $(this).data("name") + '<a class="close bcn-close" data-dismiss="alert" href="#">&times;</a></li>'); } }); And the HTML: <ul> <li><a class="account" data-name="All" href="#">All</a></li> <li><a class="account" data-name="John Smith" href="#">John Smith</a></li> </ul> <ul class="account-hidden-li"> <ul>

  • Looking for design/architecture suggestions for a simple HTML game.

    - by z-boss
    Imagine that HTML page is a game surface (see picture). User can have n number of boards (blue divs) on his page. Each board can be moved, re-sized, relabeled, created new and removed. Inside each board there are m number of figures (purple divs). Each of these user can move inside the board or to another board, re-size, change color and label, delete, add new. The goal of the game is not important, but let's say it is to rearrange figures in a certain way so that they disappear. But the goal of the programmer is to save the whole game surface in the database for every user of the site, and to load it later when he returns. So, how do I go about data exchange between client and the database? I'll give my idea in one of the answers.

  • Making a non-trivial Image and Video Gallery with a really nice interface

    - by Cawas
    Short part: I'm starting to build an Image and Video Gallery for our intranet. It's pretty much like an image gallery with video thumbnails that play on click. It's just good to keep that in mind because caching and streaming happen in very different ways there. It will serve to browse our reference database, which will also contain searching, tagging and voting. There are 3 features that I need to begin with: Quick preview of thumbnails from each Gallery Fast zoom in / out Animated scrolling Now to the long part, since I can't seem to reduce this: I hope this question belongs here. Maybe people can read this through and identify with it, specially since I expect answers to be pretty specific. The first plan was getting Apple's mobile me gallery as base, because it just so happens to have all those 3 features. If you've never seem it, you should check it out. Move the mouse over each collection and you'll get a nice preview "per pixel". Carousel got a really good scrolling, not just because of the pretty effect. I like it much more than cooliris, but it would be nice to have it in several rows, maybe without the magnifying effect... Then it could be all in the same place with the zoom. The more the features blend-in together, the better. Zooming out with the mouse, scrolling by dragging, once the zoom is really out it becomes a browsing through galleries, with the quick-show preview of each, all properly cached and fast. That'd be perfect. A very compelling interface will be important in this project. Well, my point here is just describing what I need and hope to hear from people with more experience in all that stuff of what's already done and what I'd have to do myself. And how (i.e. which framework to use) to do it. To begin with, I've found a gallery demo and its source code (I think it was from here, but the link seems broken now). I guess it was made in SproutCore, which is what mobileme was based upon. Definitely with JQuery (which already seems a little slow). But I'm still missing two features there: the carousel and the fast zoom (it's just not as slow as the zoom in this demo with cappuccino). Then I've found a supposedly better one with a pretty good and similar zoom, that I'm not sure if it's using any framework and is already in php. Right now it'd be better having just the HTML, no server-side, since I'm building interface first. So, can anyone point directions? There are way too many options! Should I look for another solution closer to what I need, or try and tweak this one? I'm not familiar with any framework at all. Sorry for bringing this question that I will have to answer myself anyway sooner or later and sorry that I couldn't make this smaller. Thanks.

  • jPlayer problem in Firefox - also throws error from jQuery?! Not related to OGG support.

    - by wolftron
    I've been working on a small SVG website, http://docroot.ca/ - the SVG part has been working out pretty well. In the current site, jPlayer is called and given an mp3. jPlayer functions properly in Safari, Chrome, and Opera, but not Firefox which throws the following two errors: Error: not well-formed Source File: Line: 1, Column: 191 Source Code: <div xmlns="http://www.w3.org/1999/xhtml"><embed name="jqjp_flash_0" id="jqjp_flash_0" src="js/Jplayer.swf" width="0" height="0" bgcolor="#ffffff" quality="high" FlashVars="id=jPlayerBox&fid=jqjp_flash_0&vol=80" allowScriptAccess="always" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" /></ and: Error: uncaught exception: [Exception... "An invalid or illegal string was specified" code: "12" nsresult: "0x8053000c (NS_ERROR_DOM_SYNTAX_ERR)" location: "https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js Line: 122"] I'm not sure why the latter happens at all. The former might have something to do with jPlayer's .swf component. The weird thing is the same code works in http://willshown.com/dw, but not in http://docroot.ca. Any guesses as to what direction to take this problem?

  • Shadowbox.js and dailymotion videos

    - by Greenie
    Hi there. I have a site set up with some thumbs and links to videos hosted on vimeo. I show them in a overlay using shadowbox.js. This works perfect. Now I want to add a video hosted on dailymotion, but it doesn't work. The working link to vimeo video: <a rel="shadowbox;height=636;width=956" href="http://vimeo.com/moogaloop.swf?clip_id=11377863&server=vimeo.com&show_title=1&show_byline=1&show_portrait=1&color=00ADEF&fullscreen=1" class="player_text">thumbnail here</a> The non working link to dailymotion video: <a rel="shadowbox;height=636;width=956" href="http://www.dailymotion.com/swf/xd6g8y?related=0&autoplay=1" class="player_text">thumbnail here</a> When the href is pasted in a browser, both links work fine. Both are played in a swf as far as I can see. So I can't see why shadowbox won't show it. Unless its a permission problem on the dailymotion video. Anyone know what I'm doing wrong?

  • Java applet for Tower of Hanoi

    - by Naren
    I am planning to write a Java applet for Tower of Hanoi similar to link( http://www.mazeworks.com/hanoi/index.htm ) Can you suggest how should I start and proceed. And, btw, does it require multi threading? And also, major part of my doubt is to make a disc being clickable and being able to drag and drop the disc on a tower. detect a tower (if a disc is being dragged using mouse)

  • Calculating usage of localStorage space

    - by WmasterJ
    I am creating an app using the Bespin editor and HTML5's localStorage. It stores all files locally and helps with grammar, uses JSLint and some other parsers for CSS and HTML to aid the user. I want to calculate how much of the localStorage limit has been used and how much there actually is. Is this possible today? I was thinking for not to simply calculate the bits that are stored. But then again I'm not sure what more is there that I can't measure myself.

  • Are there any pitfalls to var something = something || {}

    - by puk
    I came across this answer where the poster suggested that the shorthand for if(typeof MyNamespace === 'undefined'){ var MyNamespace = {}; } is var MyNamespace = MyNamespace || {}; Would veteran programmers recommend the latter to simplify the code, or does it overly complicate things, like abusing ++ or -- in complex compound statements? EDIT The reason I asked is b/c a while back someone inspired me by pointing out that a lot of the people who think they are expert programmers make a lot of beginners mistakes. The case at the time was if (isReady){ //Do Something } And what he was saying is that a condition should mean something, isReady doesn't 'mean' anything, instead, we should use if (isReady === true){ //Do Something }

  • Unique element ID, even if element doesn't have one

    - by Robert J. Walker
    I'm writing a GreaseMonkey script where I'm iterating through a bunch of elements. For each element, I need a string ID that I can use to reference that element later. The element itself doesn't have an id attribute, and I can't modify the original document to give it one (although I can make DOM changes in my script). I can't store the references in my script because when I need them, the GreaseMonkey script itself will have gone out of scope. Is there some way to get at an "internal" ID that the browser uses, for example? A Firefox-only solution is fine; a cross-browser solution that could be applied in other scenarios would be awesome. Edit: If the GreaseMonkey script is out of scope, how are you referencing the elements later? They GreaseMonkey script is adding events to DOM objects. I can't store the references in an array or some other similar mechanism because when the event fires, the array will be gone because the GreaseMonkey script will have gone out of scope. So the event needs some way to know about the element reference that the script had when the event was attached. And the element in question is not the one to which it is attached. Can't you just use a custom property on the element? Yes, but the problem is on the lookup. I'd have to resort to iterating through all the elements looking for the one that has that custom property set to the desired id. That would work, sure, but in large documents it could be very time consuming. I'm looking for something where the browser can do the lookup grunt work. Wait, can you or can you not modify the document? I can't modify the source document, but I can make DOM changes in the script. I'll clarify in the question. Can you not use closures? Closuses did turn out to work, although I initially thought they wouldn't. See my later post. It sounds like the answer to the question: "Is there some internal browser ID I could use?" is "No."

  • jsTree: Prevent before and after TYPE, only use inside

    - by Nic Hubbard
    I am using jsTree which is very nice. When dragging and dropping, I don't really care for the before and after types, I only want to use inside. Meaning, I am only concerned about that parent that a child is dropped into, rather than where the order is with other elements INSIDE the parent. So, I wanted to build my callback, so it always refers to the parent node that it is inside. But, it is not fool proof, yet. onmove : function (NODE,REF_NODE,TYPE,TREE_OBJ,RB) { if (TYPE == 'inside') { alert('Item to move:'+$(NODE).attr('rel')+' to '+$(REF_NODE).attr('rel')+' '+TYPE); } else if (TYPE == 'after') { alert('Item to move:'+$(NODE).attr('rel')+' to '+$(REF_NODE).parent().parent('li').attr('rel')+' '+TYPE); } }, Does anyone have suggestions, how I can change my callback, so that the REF_NODE is always the parent that the NODE is moved into? Rather than a sibling of, which is a child of the parent?

  • jQuery - ASPX Security libraries

    - by Jean Paul
    Hello. I would like to know if there's a combo like jCryption ([jCryption]) - PHP but for jQuery - ASPX. I mean, I have been searching for a combo to send data both ways (Client-server, server-client) with jQuery to ASPX. The best I found was jCryption that sends data from JavaScrpit to PHP. I need a combo to send data from JavaScrpit to ASPX. Any ideas?? PD: Please don't tell me to use HTTPS, it's not enough to ensure the data communication on a client - server application.

  • Correct usage of addEventListener() /attachEvent()?

    - by ginny
    Hi guys! I'm wondering how to use "addEventListener" resp. "attachEvent" correctly!? window.onload=function(myFunc1){ // do something } function myFunc2(){ // do something } if (window.addEventListener){ window.addEventListener('load', myFunc2, false); } else if (window.attachEvent){ window.attachEvent('onload', myFunc2); } ... or function myFunc1(){ // do something } if (window.addEventListener){ window.addEventListener('load', myFunc1, false); } else if (window.attachEvent){ window.attachEvent('onload', myFunc1); } function myFunc2(){ // do something } if (window.addEventListener){ window.addEventListener('load', myFunc2, false); } else if (window.attachEvent){ window.attachEvent('onload', myFunc2); } ... ? Is this cross-browser secure or should I better go with sth. like this: function myFunc1(){ // do something } function myFunc2(){ // do something } ... function addOnloadEvent(fnc){ if ( typeof window.addEventListener != "undefined" ) window.addEventListener( "load", fnc, false ); else if ( typeof window.attachEvent != "undefined" ) { window.attachEvent( "onload", fnc ); } else { if ( window.onload != null ) { var oldOnload = window.onload; window.onload = function ( e ) { oldOnload( e ); window[fnc](); }; } else window.onload = fnc; } } addOnloadEvent(myFunc1); addOnloadEvent(myFunc2); ... AND: Say "myfunc2" is for IE 7 only. How to modify the correct/preferred method accordingly? Thank you so much!

  • Load external pages using jquery

    - by user1688011
    I'm trying to use jquery to load external pages into the current without reloading. Apparently everything works fine except of one little issue, I hope I'll be clear as much as possible. When I call the page 'info.php' it is loaded into the #content div. That's what the script supposed to do, the problem is that in the main page, which contains the script and the #content div, I already have some code that I want it to be executed when someone visit the page and not to be called from external page. That is actually the case but when I click on one of the links in the menu, I can't go back to the initial content.. <script> $(function() { $('#nav a').click(function() { var page = $(this).attr('href'); $('#content').load(page + '.php'); return false; }); }); </script> <ul id="nav"> <li><a href="#">Page1</a></li> <li><a href="about">About</a></li> <li><a href="contact">Contact</a></li> <li><a href="info">Info</a></li> </ul> <div id="content"> Here I have some code that I wanted to be attributed to the "Page1" </div> Do you have any suggestions how to fix this issue? Thanks

  • Why does the jQuery on this page work for Internet Explorer 8, but nothing else?

    - by Ben McCormack
    I made a web page that uses jQuery: http://benmccormack.com/demo/MichaelMassPsalm/Psalm16Mode5.html When you change the selection in the combo box from Higher Key to Lower Key, all of the music images are supposed to change their source to be images that represent the lower key signature. This works great in IE8, but it won't work in Safari, Firefox, or Chrome. Why not? Here's the jQuery code that I'm using: $(document).ready(function () { $("#musicKey").change(function (event) { if ($("#musicKey").val() * 1) { $("img[src*='Low'").each(function (index) { $(this).attr("src", $(this).attr("src").replace("Low", "High")); }); } else { $("img[src*='High'").each(function (index) { $(this).attr("src", $(this).attr("src").replace("High", "Low")); }); } }); });

  • jQuery ready function

    Can anyone tell me why the document ready function needs a call to function first please? I've been told that the setTimeout in the first below example (which does not work) would be evaluated and passed to ready, but I don't see what the difference would be for the function call in the second example (which works)? $(document).ready( setTimeout( function(){ $('#set_3').innerfade({ animationtype: 'fade', speed: 'slow', timeout: 3000, type: 'sequence', containerheight: '180' }); }, 2000); ); $(document).ready( function(){ setTimeout( function(){ $('#set_3').innerfade({ animationtype: 'fade', speed: 'slow', timeout: 3000, type: 'sequence', containerheight: '180' }); }, 2000); } );
