Pass mousewheel event through fixed content

Question

The best way to understand this is to look at this fiddle.

Notice how mouse wheel over the fixed content in the red box does nothing. I would like the

I think this does what you're asking for!

$('#fixed').bind('mousewheel', function(e){
     var scrollTo= (e.wheelDelta*-1) + $('#container').scrollTop();
    $("#container").scrollTop(scrollTo);
});

EDIT: Updated the jsFiddle link to one that actually works
DOUBLE EDIT: Best to dispense with the .animate() on further testing...

TRIPLE EDIT: Much less pretty (and will probably be horribly slow with a lot of elements on the page), but this works and I owe a lot to this stackoverflow answer.

$('#fixed').bind('mousewheel', function(e) {


var potentialScrollElements = findIntersectors($('#fixed'), $('*:not(#fixed,body,html)'));
$.each(potentialScrollElements, function(index, Element) {
    var hasVerticalScrollbar = $(Element)[0].scrollHeight > $(Element)[0].clientHeight;
    if (hasVerticalScrollbar) {
        var scrollTo = (e.wheelDelta * -1) + $(Element).scrollTop();
        $(Element).scrollTop(scrollTo);
    }
});
});


function findIntersectors(targetSelector, intersectorsSelector) {
var intersectors = [];

var $target = $(targetSelector);
var tAxis = $target.offset();
var t_x = [tAxis.left, tAxis.left + $target.outerWidth()];
var t_y = [tAxis.top, tAxis.top + $target.outerHeight()];

$(intersectorsSelector).each(function() {
    var $this = $(this);
    var thisPos = $this.offset();
    var i_x = [thisPos.left, thisPos.left + $this.outerWidth()]
    var i_y = [thisPos.top, thisPos.top + $this.outerHeight()];

    if (t_x[0] < i_x[1] && t_x[1] > i_x[0] && t_y[0] < i_y[1] && t_y[1] > i_y[0]) {
        intersectors.push($this);
    }

});
return intersectors;

}
