JavaScript Shorthand for a jQuery If-Else Snippet

I have this snippet of code:

<script type="text/javascript">
$(window).load(function() {
    if(!$.browser.msie){ 
        $('#myDiv').animate({opacity: 1}, 300);
    } else if ($.browser.msie) {
        $('#myDiv').css({opacity:1});
    }
}); 
</script>

How can I say the same thing using the " : something ? somethingElse " syntax?

Thanks in advance?

Not sure I got the question, however:

$.browser.msie ? $('#myDiv').css({opacity: 1}) : $('#myDiv').animate({opacity: 1}, 300);

Also, I'm not an expert of IE anymore, but I wonder if you could do something like:

$('#myDiv').animate({opacity: 1}, $.browser.msie ? 0 : 300);

That should be applied immediately, and made it more readable with an external variable:

var speed = $.browser.msie ? 0 : 300;
$('#myDiv').animate({opacity: 1}, speed);

Or something like that.

You can do it like this:

$(window).load(function() {
    $.browser.msie ? $('#myDiv').css({opacity:1}); : $('#myDiv').animate({opacity: 1}, 300);
});

I wouldn't recommend it for at least two reasons (browser sniffing, and readability), but you can.

Another way:

$(window).load(function() {
    $('#myDiv')[$.browser.msie ? 'css' : 'animate']({opacity:1}, $.browser.msie ? undefined : 300);
});

...but that's even worse. ;-)
