  • Speeding up jQuery empty() or replaceWith() Functions When Dealing with Large DOM Elements

    - by Levi Hackwith
    Let me start off by apologizing for not giving a code snippet. The project I'm working on is proprietary and I'm afraid I can't show exactly what I'm working on. However, I'll do my best to be descriptive. Here's a breakdown of what goes on in my application: User clicks a button Server retrieves a list of images in the form of a data-table Each row in the table contains 8 data-cells that in turn each contain one hyperlink Each request by the user can contain up to 50 rows (I can change this number if need be) That means the table contains upwards of 800 individual DOM elements My analysis shows that jQuery("#dataTable").empty() and jQuery("#dataTable).replaceWith(tableCloneObject) take up 97% of my overall processing time and take on average 4 - 6 seconds to complete. I'm looking for a way to speed up either of the above mentioned jQuery functions when dealing with massive DOM elements that need to be removed / replaced. I hope my explanation helps.

  • How can I add styles to dynamically added table cells?

    - by Doc Hoffiday
    In my program I have a table that, when loaded, has jQuery add some styles/classes to the table cells and table headers. Everything works fine until rows are added via functionality on the rest of the page. Instead of adding the classes to the table cell during addition, is it possible to "listen" or fire some event that checks to see if child elements were added to the table. Essentially, I want something functionally equivalent to this: $("#table td").live("ready", function(){ // do something }); but the live/ready won't work on a table cell... Any ideas?

    - by Cptcecil
    I'm using JQuery and Prototype in this web application that I'm developing. I'm looking for a way to use Lightbox v2.04 by Lokesh Dhakar to play flash movies. If its not possible using the Lightbox v2.04 then what other ways can I accomplish the shadowing overlayed flash video pop-up with jquery and/or Prototype? The reason I'm set on v2.04 is because I'm using it already as an image gallery. I'm using flv type flash files if that helps.

  • Understanding a skeleton 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?

  • Dojo: dijit.form.DropDownButton content not positioned correctly

    - by Staale
    I have the following setup: <div dojoType="dijit.form.DropDownButton"> <span>Modify</span> <div dojoType="dijit.Menu"> <div dojoType="dijit.MenuItem">...</div> </div> </div> There is of course more to the final setup. The problem I Have is that if I scroll in the page, the popup menu under the DropDownButton comes much higher in the page. I suspect that it's subtracting the scrollOffset for the position off the popup, while in reality that is not needed. Anyone got any tips about how to fix this? I would prefer to use declerative html syntax for using Dojo widgets. == Fixed == I updated to dojo 1.4.2 and this got fixed then.

  • How do you make an image opened in colorbox scrollable

    - by nicholas.alipaz
    I would like my images that I open in colorbox to be displayed fullsize with no resizing applied to them and then apply scrollbars to allow for viewing the larger images. Some of my images are quite tall and things get pixelated when resized down. Currently colorbox just resizes my images down to the size of the available height/width. Is there a way to make all images display fullsize with overflow scrollable in colorbox? I am linking directly to an image: <a href="/myimage.png" title="My Image" class="colorbox imagefield imagefield-imagelink imagefield-field_portfolio_screenshot initColorbox-processed cboxElement" rel="gallery-12"> <img src="/thumb/myimage.png" alt="image" title="My Image" class="imagecache imagecache-portfolio_screenshot_thumb" height="50" width="50"> </a>

  • jQuery - I'm getting unexpected outputs from a basic math formula.

    - by OllieMcCarthy
    Hi I would like to start by saying I'd greatly appreciate anyones help on this. I have built a small caculator to calculate the amount a consumer can save annually on energy by installing a ground heat pump or solar panels. As far as I can tell the mathematical formulas are correct and my client verified this yesterday when I showed him the code. Two problems. The first is that the calculator is outputting ridiculously large numbers for the first result. The second problem is that the solar result is only working when there are no zeros in the fields. Are there some quirks as to how one would write mathematical formulas in JS or jQuery? Any help greatly appreciated. Here is the link - http://www.olliemccarthy.com/test/johncmurphy/?page_id=249 And here is the code for the entire function - $jq(document).ready(function(){ // Energy Bill Saver // Declare Variables var A = ""; // Input for Oil var B = ""; // Input for Storage Heater var C = ""; // Input for Natural Gas var D = ""; // Input for LPG var E = ""; // Input for Coal var F = ""; // Input for Wood Pellets var G = ""; // Input for Number of Occupants var J = ""; var K = ""; var H = ""; var I = ""; // Declare Constants var a = "0.0816"; // Rate for Oil var b = "0.0963"; // Rate for NightRate var c = "0.0558"; // Rate for Gas var d = "0.1579"; // Rate for LPG var e = "0.121"; // Rate for Coal var f = "0.0828"; // Rate for Pellets var g = "0.02675"; // Rate for Heat Pump var x = "1226.4"; // Splittin up I to avoid error var S1 = ""; // Splitting up the calcuation for I var S2 = ""; // Splitting up the calcuation for I var S3 = ""; // Splitting up the calcuation for I var S4 = ""; // Splitting up the calcuation for I var S5 = ""; // Splitting up the calcuation for I var S6 = ""; // Splitting up the calcuation for I // Calculate H (Ground Sourced Heat Pump) $jq(".es-calculate").click(function(){ $jq(".es-result-wrap").slideDown(300); A = $jq("input.es-oil").val(); B = $jq("input.es-storage").val(); C = $jq("input.es-gas").val(); D = $jq("input.es-lpg").val(); E = $jq("input.es-coal").val(); F = $jq("input.es-pellets").val(); G = $jq("input.es-occupants").val(); J = ( A / a ) + ( B / b ) + ( C / c ) + ( D / d ) + ( E / e ) + ( F / f ) ; H = A + B + C + D + E + F - ( J * g ) ; K = ( G * x ) ; if ( A !== "0" ) { S1 = ( ( ( A / a ) / J ) * K * a ) ; } else { S1 = "0" ; } if ( B !== "0" ) { S2 = ( ( ( B / b ) / J ) * K * b ) ; } else { S2 = "0" ; } if ( C !== "0" ) { S3 = ( ( ( C / c ) / J ) * K * c ) ; } else { S3 = "0" ; } if ( D !== "0" ) { S4 = ( ( ( D / d ) / J ) * K * d ) ; } else { S4 = "0" ; } if ( E !== "0" ) { S5 = ( ( ( E / e ) / J ) * K * e ) ; } else { S5 = "0" ; } if ( F !== "0" ) { S6 = ( ( ( F / f ) / J ) * K * f ) ; } else { S6 = "0" ; } I = S1 + S2 + S3 + S4 + S5 + S6 ; if(!isNaN(H)) {$jq("span.es-result-span-h").text(H.toFixed(2));} else{$jq("span.es-result-span-h").text('Error: Please enter numerals only');} if(!isNaN(I)) {$jq("span.es-result-span-i").text(I.toFixed(2));} else{$jq("span.es-result-span-i").text('Error: Please enter numerals only');} }); });

  • Checking if radio buttons are checked in Firefox

    - by Andrew Song
    On my site, I have two checkboxes created in my ASP.NET MVC view like so: Html.RadioButton("check", "true", "true" == (string) ViewData["someKey"], new { id = "check1"}); Html.RadioButton("check", "false", "false" == (string) ViewData["someKey"], new { id = "check2"}); I am positive that ViewData["someKey"] has the value "true" in it. In my JS init function, I perform the following check: alert($('#check1').is(':checked') + " " + $('#check2').is(':checked')); In Firefox (and only Firefox), my alert dialog will show the following (it works as expected in every other browser): Initial page load: true false Normal refresh via Ctrl + R: false false Refresh skipping cache via Ctrl + Shift + R: true false I have tried many different methods of looking at the checkbox value, including $('#check1').attr('checked') without success. If I examine the HTML in Firebug, I can see that the first radio button has the property checked="checked" in it. Why is the checkbox value changing in FF when I refresh, and how can I mitigate this? Since this seems to be a FF-only bug, how can I change my code to make it work? This SO question seemed to ask something similar, but none of the proposed solutions seem to work in this case. Edit: I should also point out that when the radio button is rendered after the refresh in FF, it's not actually being displayed as checked either, despite what the HTML is telling me. Edit2: Adding raw HTML as per request <input id="check1" type="radio" value="True" name="check" checked="checked"/> <input id="check2" type="radio" value="False" name="check"/>

  • Prototype mouseleave for two elements

    - by TenJack
    I have created a small navigation element that is positioned right on top of another element. It is only shown when a user mousenters/mouseovers the main element. I am having some trouble with the prototype. I would like this small nav element to be hidden when a user mouses out of the main box, but I would also like the small nav element to remain visible if a user mouses out of the main box but mouses into the small nav at the same time. This is my attempt so far with some pseudo-code to hopefully explain: $('main_box').observe('mouseenter', function(){ $('small_div').show() }) $('main_box').observe('mouseleave', function(){ if this element is $('small_div') then Event.stop() $('small_div').observe('mouseleave', function(){ if this element is $('main_box') Event.stop observe $('main_box') mouseleave else $('small_div').hide(); }) else $('small_div').hide(); }) The main thing I'm having trouble with is figuring out what element the mouse is over at a given point in time. Is there a way to do something like: on mouseleave do blah unless the mouse is over a specific element then do not do blah?

    - by Anders
    I'm trying to find a generic way of getting the name of Constructors. My goal is to create a Convention over configuration framework for KnockoutJS My idea is to iterate over all objects in the window and when I find the contructor i'm looking for then I can use the index to get the name of the contructor The code sofar (function() { constructors = {}; window.findConstructorName = function(instance) { var constructor = instance.constructor; var name = constructors[constructor]; if(name !== undefined) { return name; } var traversed = []; var nestedFind = function(root) { if(typeof root == "function" || traversed[root]) { return } traversed[root] = true; for(var index in root) { if(root[index] == constructor) { return index; } var found = nestedFind(root[index]); if(found !== undefined) { return found; } } } name = nestedFind(window); constructors[constructor] = name; return name; } })(); var MyApp = {}; MyApp.Foo = function() { }; var instance = new MyApp.Foo(); console.log(findConstructorName(instance)); The problem is that I get a Permission denied to access property 'toString' Exception, and i cant even try catch so see which object is causing the problem Fiddle http://jsfiddle.net/4ZwaV/

  • jQuery-Ui Ajax Tabs bug?

    - by vsync
    I have a JSON that returns from the server which tabs to build, so I init them in my JS like this: $('#tabs').tabs( 'ajaxOptions', { timeout: 20000, error: function(xhr, status, index, anchor){ console.log( status, index, anchor ); } }) .tabs('add', item.CategoryLink, item.CategoryName); Thing is, when I click a tab, and before it is done loading I click another tab, the previous request is aborted and never called again when I click that first one again! this is very bad, because it obviously didn't fetch the request, so what gives? I tried bypassing this by setting: .tabs({ cache: false }) but this is a bad thing to do, because I don't want to have a request each time again... it should be cachced if response was sent. using jquery-ui 1.8.1

  • Creating Dynamic variables from json response

    - by c0mrade
    My JSON response looks like this : {"sample":[{"id":"2","name":"branch name"},{"id":"3","name":"branch name 2"}]} My function looks like this : function getJSONObjects(){ $.getJSON("http://localhost/api/branches", function(data){ $.each(data.sample, function(i,item){ var loc = "branch"; eval("var " + loc + item.id + "=123;"); alert(loc + item.id); }); }); } The idea is to create branch + id object so I can do something with it(create marker on a map), so I tried to assign it any value to see if this was working. I wanted both branch2 and branch3 to alert 123 so I have something to start with. But currently this alerts branch2 and branch3 instead of 123. I have little experience with creating dynamic variables/objects can someone tell me what I'm doing wrong or maybe another approach towards solving this?

Is there any way to make them total invisible? i.e., what I'm trying to do is make it as though the banner is a solid color, even though it's a gradient. Thanks in advance for any help!
