  • Keep a div from reloading

    - by Josh
    Basically, I want the same effect as the oldschool html 'frameset' I think. Take a look at this page please: http://onomadesign.com/wordpress/identity-design/alteon-a-boeing-company/ If a user selects a project from industry - transportation for example, I would like that the right scrollmenu keeps its initial state when the new project page comes up. So they won't get lost and have to click again to be in the same submenu section. So, the right thumbnail navigation should stay in the same way, I don't want it to reload. Do I have to do it with frames or iframes? Or can I make some kind of jQuery call to 'not reload' that div? Maybe PHP? I'm sorry, I am not a programmer from origin. Thanks in advance.

  • Canvas scroll animation not working correctly

    - by pedalpete
    I'm building a gantt chart style timeline using html canvas element. I am currently attempting to add the functionality which allows the user to click a next/prev button to have the gantt chart scroll to display earlier or later times. The way I am doing this is to have a span.adjustTime where the id holds a value in seconds for the time to be adjusted (eg 86400 for one day). I am trying to animate the scrolling so it looks like a scroll, rather than jumping ahead by one day. I have a small problem in my timing calculation, but the script below is not animating, but rather jumping directly to the final time. I do have the draw function running on a separate setInterval which updates every second, so I'm hoping it isn't an issue of conflicting timers on the same function on the same element and data. jQuery('span.adjustTime').click(function() { var adjustBy = parseInt(jQuery(this).attr('id').replace('a', '')); var data = jQuery('img#logo').data(); for(var m = 1; m >= 30; m++) { gantt.startUnixTime = gantt.startUnixTime + (adjustBy * (m * 0.001)); var moveTimer = setTimeout(function() { draw(document.getElementById('gantt'), data, gantt); }, 1000); if (m == 30) { clearTimeout(moveTimer); } } });

  • How do I convert an AMD module from a singleton to an instance?

    - by Jamie Ide
    I'm trying to convert a working Durandal view model module from a singleton to an instance. The original working version followed this pattern: define(['knockout'], function(ko) { var vm = { activate: activate, companyId: null; company: ko.observable({}) }; return vm; function activate(companyId) { vm.companyId = companyId; //get company data then vm.company(data); } } The new version exports a function so that I get a new instance on every request... define(['knockout'], function(ko) { var vm = function() { activate = activate; companyId = null; company = ko.observable({}); }; return vm; function activate(companyId) { vm.companyId = companyId; //get company data then vm.company(data); } } The error I'm getting is "object function () [...function signature...] has no method company on the line vm.company(data);. What am I doing wrong? Why can I set the property but can't access the knockout observable? How should I refactor the original code so that I get a new instance on every request? My efforts to simplify the code for this question hid the actual problem. My real code was using Q promises and calling two methods with Q.All. Since Q is in the global namespace, it couldn't resolve my viewmodel after converting to a function. Passing the view model to the methods called by Q resolved the problem.

  • jquery google visual api graph's data rows does not work.

    - by marharépa
    Hi! I'd like to use google drawVisualization API. Example: var data = new google.visualization.DataTable(); data.addColumn('string'); data.addColumn('number'); data.addRows([ ['a', 14], ['b', 47], ['c', 80], ['d', 55], ['e', 16], ['f', 90], ['g', 29], ['h', 23], ['i', 58], ['j', 48] ]); My version gets elements by an other google api, and join them, and after place the variable between ([ and ]), to be like in the example. var outputGraph = []; for (var i = 0, entry; entry = entries[i]; ++i) { var asd = [ entry.getValueOf('ga:pageTitle'), entry.getValueOf('ga:pageviews') ].join("',"); outputGraph.push(" ['" + asd + "]"); //get the 2 elements and join them to be like ['asd', 2], } // this is fine, the outputgraph is like ['asd', 2], ['asd', 2], ['asd', 2] as seen in the example var outputGraphFine = ("(["+outputGraph+"])"); // i suggest this is which fails the script. var data = new google.visualization.DataTable(); data.addColumn('string', 'Task'); data.addColumn('number', 'Hours per Day'); data.addRows = outputGraphFine; But it doesn't work. Why?

  • Waiting on multiple asynchronous calls to complete before continuing

    - by Chad
    So, I have a page that loads and through jquery.get makes several requests to populate drop downs with their values. $(function() { LoadCategories($('#Category')); LoadPositions($('#Position')); LoadDepartments($('#Department')); LoadContact(); }; It then calls LoadContact(); Which does another call, and when it returns it populates all the fields on the form. The problem is that often, the dropdowns aren't all populated, and thus, it can't set them to the correct value. What I need to be able to do, is somehow have LoadContact only execute once the other methods are complete and callbacks done executing. But, I don't want to have to put a bunch of flags in the end of the drop down population callbacks, that I then check, and have to have a recursive setTimeout call checking, prior to calling LoadContact(); Is there something in jQuery that allows me to say, "Execute this, when all of these are done."?

  • Show / Hiding Divs

    - by Rob
    After cobbling together a few questions I've managed to get this far to showing / hiding divs: $(document).ready(function(){ $('.box').hide(); $('#categories').onMouseOver(function() { $('.box').hide(); $('#div' + $(this).val()).show(); }); }); HTML: <div id="categories"> <div id="btn-top20"><a href="">Top 20 Villas</a></div> <div id="btn-villaspec"><a href="">Villa Specials</a></div> <div id="btn-staffpicks"><a href="">Our Staff Picks</a></div> </div> <div id="category-content"> <div id="divarea1" class="box"> Content 1 </div> <div id="divarea2" class="box"> Content 2 </div> <div id="divarea3" class="box"> Content 3 </div> </div> What am I missing?

  • convert list of relative widths to pixel widths

    - by mkoryak
    This is a code review question more then anything. I have the following problem: Given a list of relative widths (no unit whatsoever, just all relative to each other), generate a list of pixel widths so that these pixel widths have the same proportions as the original list. input: list of proportions, total pixel width. output: list of pixel widths, where each width is an int, and the sum of these equals the total width. Code: var sizes = "1,2,3,5,7,10".split(","); //initial proportions var totalWidth = 1024; // total pixel width var sizesTotal = 0; for (var i = 0; i < sizes.length; i++) { sizesTotal += parseInt(sizes[i], 10); } if(sizesTotal != 100){ var totalLeft = 100;; for (var i = 0; i < sizes.length; i++) { sizes[i] = Math.floor(parseInt(sizes[i], 10) / sizesTotal * 100); totalLeft -= sizes[i]; } sizes[sizes.lengh - 1] = totalLeft; } totalLeft = totalWidth; for (var i = 0; i < sizes.length; i++) { widths[i] = Math.floor(totalWidth / 100 * sizes[i]) totalLeft -= widths[i]; } widths[sizes.lenght - 1] = totalLeft; //return widths which contains a list of INT pixel sizes

  • Why is this bookmarklet code saying jQuery is not defined even though jQuery is included?

    - by Josh Brown
    I am creating a bookmarklet and the code below is not working on first try. When I goto a page, it says "jQuery is not defined". But, if I click it again, it works perfectly? var qrcodetogo = { jQURL: 'http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js', jQUIURL: 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/jquery-ui.min.js', jQUIThemeURL: 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/themes/ui-lightness/jquery-ui.css', init: function(){ this.createLink('qrcodetogo_UI-Lightness', this.jQUIThemeURL); this.createScript('qrcodetogo_jQuery', this.jQURL); this.createScript('qrcodetogo_jQueryUI', this.jQUIURL); this.createHiddenDiv('qrcodetogo_dialog','This is a Test.'); jQuery.noConflict(); }, showQRCode: function() { jQuery('#qrcodetogo_dialog').dialog(); }, createLink: function(id, url) { var l = document.createElement('link'); l.href = url; l.rel = 'stylesheet'; l.type = 'text/css'; l.media = 'screen'; l.charset = 'utf-8'; document.getElementsByTagName('head')[0].appendChild(l); }, createScript: function(id, url) { var s = document.createElement('script'); s.src = url; s.id = id; document.getElementsByTagName('head')[0].appendChild(s); }, createHiddenDiv: function(id, body) { var div = document.createElement('div'); div.id = id; div.innerHTML = body; div.style.display = 'none'; document.getElementsByTagName('body')[0].appendChild(div) } } qrcodetogo.init(); qrcodetogo.showQRCode();

  • What is the proper way to credit public code snippets?

    - by Babiker
    This question might not be a programming problem, but its been bothering me. There is a lot of free js/css scripts out there for public use. I some times use these scripts. If any, what is the formal and proper way to credit these snippets when all i have is a name of a website and a url. I understand that a simple comment might get the job done but i wanted to know whether there is a more professional way.

  • How can I convert seconds to minutes in jQuery while updating an element with the current time?

    - by pghtech
    So I see a number of ways to display allot of seconds in a (static) hr/min/sec. However, I am trying to produce a visual count down timer: $('#someelement').html(minCounter + ' minutes ' + ((secCounter == 0) ? '' : (secCounter + ' seconds'))); My counter is reduced inside a SetInterval that triggers ever 1 second: //....... var counter = redirectTimer; jQuery('#WarningDialogMsg').html(minCounter + ' minutes ' + ((secCounter == 0) ? '' : (secCounter + ' seconds'))); //........ SetInternval( function() { counter -= 1; secCounter = Math.floor(counter % 60); minCounter = Math.floor(counter / 60); //....... $('#someelement').html(minCounter + ' minutes ' + ((secCounter == 0) ? '' : (secCounter + ' seconds'))); }, 1000) It is a two minute counter but I don't want to display 120 seconds. I want to display 1 : 59 (and counting down). I have managed to get it to work using the above, but my main question is: is there a more elegant way to accomplish the above? (note: I am redirecting once "counter == 0").

  • How to use jQuery to assign a class to only one radio button in a group when user clicks on it?

    - by xraminx
    I have the following markup. I would like to add class_A to <p class="subitem-text"> (that holds the radio button and the label) when user clicks on the <input> or <label>. If user clicks some other radio-button/label in the same group, I would like to add class_A to this radio-button's parent paragraph and remove class_A from any other paragraph that hold radio-buttons/labels in that group. Effectively, in each <li>, only one <p class="subitem-text"> should have class_A added to it. Is there a jQuery plug-in that does this? Or is there a simple trick that can do this? <ul> <li> <div class="myitem-wrapper" id="10"> <div class="myitem clearfix"> <span class="number">1</span> <div class="item-text">Some text here </div> </div> <p class="subitem-text"> <input type="radio" name="10" value="15" id="99"> <label for="99">First subitem </label> </p> <p class="subitem-text"> <input type="radio" name="10" value="77" id="21"> <label for="21">Second subitem</label> </p> </div> </li> <li> <div class="myitem-wrapper" id="11"> <div class="myitem clearfix"> <span class="number">2</span> <div class="item-text">Some other text here ... </div> </div> <p class="subitem-text"> <input type="radio" name="11" value="32" id="201"> <label for="201">First subitem ... </label> </p> <p class="subitem-text"> <input type="radio" name="11" value="68" id="205"> <label for="205">Second subitem ...</label> </p> <p class="subitem-text"> <input type="radio" name="11" value="160" id="206"> <label for="206">Third subitem ...</label> </p> </div> </li>

  • how to modify this jquery syntax

    - by Gandalf StormCrow
    Hi all, this example below works when hover event is trigered and when its not, its working for elements already in DOM, but when element created dynamically it doesn't work, I realize I need to use jQuery live() or delegate() for this, the thing is I tried to modify it and its not producing the results as expected, here is the working code : $(".sidebar li").hover( function(){ $(this).css("background-color", "#F9F4D0"); $(this).append($('<button class="promoter" type="button" title="Active promotion"></button>')); }, function(){ $(this).css("background-color", "#F9FAFA"); $(this).children("button").remove(); } ); Here is the bit when I wanted to add live but it's not producing correct results : $(".sidebar li").live('hover', function(){ $(this).css("background-color", "#F9F4D0"); $(this).append($('<button class="promoter" type="button" title="Active promotion"></button>')); }, function(){ $(this).css("background-color", "#F9FAFA"); $(this).children("button").remove(); } ); Where did I made mistake, thank you

  • whats faster, more efficient, loading a js file with arrays or populating arrays from tables

    - by Leigh
    I am rebuilding an ecom site where the product data is stored in a multidimensional JS array that gets loaded on page load. This data is constantly being accessed with JS due to the nature of the site, to update prices based on user selections. There are many options that affect final price. From a programming standpoint, a DB table is much easier to maintain and update than are JS arrays, and since I am porting the site over to PHP and MYSQL, I have been considering moving these arrays into tables. So, would it be better to populate an array from the DB on load so that the pricing data is always available to the JS, or stay with hard coded JS files? I considered getting data via ajax as needed, but since this site has to constantly update pricing with user interaction, I have pretty much ruled that out. How would you handle it?

  • Creating an array & outputting its code definition for preloading

    - by user422318
    I want to create a 2d array that represents my 2d canvas. For each pixel, I will look up the value and then save an integer {0, 1, 2, 3, 4} as each element of the array. Unfortunately, this takes way too friggin' long to run each time I load the game. How can I write a script that creates this array for me and outputs the array code so I can just paste it in a js file and have it preloaded? (I'm prototyping a game, so I just need to run this for my test map or two.)

  • Is document.links faster in finding a link using jQuery?

    - by vsync
    Is this faster: $(document.links).filter('a.someClass') than just plain old this: $('a.someClass') ? I don't see anywhere in jQuery's code the utilization of document.links which gives you the collection of links on the document right away, than, it would seem, it would be faster to just filter in the collection instead of all the DOM nodes, which is alot more nodes to go over.
