I am looking for the best performing script for providing a hover state to rows within a grid.
90% of users have ie6 clients therefore I cant rely on css :hover
The grid is a standard table, some cells have inner tables.
I originally started using the .live method with mouseover and mouseout, however this has massive cpu implicatio...
I was working on this carousel thing, using the iCarousel. It works pretty nicely with a few images, using MooTools. However when I added 70 pictures (around 30k each) it stopped working so nicely. Having spent some time poking around in the code of iCarousel it looked pretty decent and stable. So this got me thinking: is the problem inh...

I've been using JQuery for a while, but primarily without plugins - I'm now looking to do a project which could take advantage of a bunch of plugins - Are there any performance penalty to using a lot of plugins in a project - Lets say something in the order of 10-20 plugins?
And how will the performance be affected if JQuery and it's pl...
I'm currently fighting with Internet Explorer's (IE7) javascript performance issues, and struggling to find good information on improving performance, whether it be for a specific browser or in general.
I think it will be helpful to all of us to have a link/tips/hints collection on improving JavaScript performance. Feel free to post wha...

In the following Code:
<script type="text/javascript">
$(function()
{
$("#accordion").accordion();
$("#datepicker").datepicker();
$("#button").click(f...
I am not a huge JavaScript performance guru. Simply wondering, can I make the following code anymore compact? Not as in packing or compressing it, but in the way it's written.
(function() {
var jq = document.createElement('script');
var an = document.createElement('script');
var cm = document.createElement('script');
var...
Could someone prove to me that the advice given here (copied below) regarding removing dom elements before altering them and then re-inserting them is ever quicker.
By prove, I would like to see some figures. Its great that they research this but I think the article is very weak without including specifics as to what the 'problem' actu...
