Javascript "this" Losing Context In Ie

The following works fine in firefox/safari/chrome, in IE, 'this' appears to be losing context in the handleEvent() function...the result of the alert is [object Window], which is n

Solution 1:

.attachEvent() doesn't give you this as the element. You'd need to wrap the handler in a function that invokes it from the context of the element to which it is attached.

    if( this.element.attachEvent ) {
        var that = this;
        this.element.attachEvent("onclick", function() { 
                                              that.handleEvent.call( that.element );
                                           } );
    }
