Updated: Hover for non-anchor elements in IE6

The updated version of the previous version of Hover for non-anchor elements in IE 6.

Before proceeding further, here’s a brief description of the problem,

The ‘:hover’ pseudo-class works on all visual elements in IE 7+, FF, Safari, Chrome and Opera. But for obvious reasons IE 6 fails to recognize the ‘:hover’ pseudo-class for elements other than the anchor(<a></a>).

Here is the updated code, which is faster and is targeted only IE 6 by a combination of JavaScript conditional comments & feature detection.

    (function ($) {
        $(document).ready(function () {
            $.single=function(a){return function(b){a[0]=b;return a}}($([1]));
                if (!window.XMLHttpRequest) {
                    $('.hoverable').each(function () {
                        this.attachEvent('onmouseenter', function (evt) { $.single(evt.srcElement).addClass('hovered'); });
                        this.attachEvent('onmouseleave', function (evt) { $.single(evt.srcElement).removeClass('hovered'); });

All you’ve to do is to include this script in your html document and add the class ‘hoverable’ to all the non-anchor elements to which you want the hover action. And in your stylesheet add an extra selector for the element along with the ‘:hover’ style definition. Look at the code of the updated example to get a clear idea.

I’ve used James Padolsey’s single jQuery object snippet in the event handlers to prevent the creation of a new jQuery object every time the event handler is executed, hence saving a few execution cycles and memory.
