jQuery .support() implementation

[WHITEB0X]

Hi Guys! I'm new to this forum and have a great question to kick things off
Can someone please take a look at the following block of code. It's a jQuery plugin that adds a hash as well as a class to the clicked link. I happen to be fading transparent PNG's and I need to EXCLUDE Internet Explorer from recognizing the fade effect as it produces a black "fuzz" when it fades. can someone teach me how to use something like this:

var FADE_TIME = 500; if(!($.support.opacity)) { FADE_TIME = 0}

$('element').fadeOut(FADE_TIME)

And Place it inside the plugin somewhere to do this? I need help quick!!

$(function() {

    var newHash      = "",
        $mainContent = $("#main-content"),
        $pageWrap    = $("#page-wrap"),
        baseHeight   = 0,
        $el;
        

    
    $("nav#footer").delegate("a", "click", function() {
        window.location.hash = $(this).attr("href");
        return false;
    });
    
    $(window).bind('hashchange', function(){
    
        newHash = window.location.hash.substring(1);
        
        if (newHash) {
            $mainContent
                .find("#guts")
                .fadeOut(200, function() {
                    $mainContent.show().load(newHash + " #guts", function() {
                        $mainContent.fadeIn(200, function() {
                        });
                        $("nav#footer a").removeClass("current");
                        $("nav#footer a[href="+newHash+"]").addClass("current");
                    });
                });
        };
        
    });
    
    $(window).trigger('hashchange');

});

You have to generally disable fadeIn() for IE, i. e. just invoke show() if opacity isn’t supported. Something like:

if($.support.opacity) {
  $('element').fadeIn(500);
}
else {
  $('element').show();
}

But I can’t tell you where to insert that in your code as I have no idea what it’s supposed to do.
