为什么时间不在代码中？

Question

我有一个随机的图片代码，但时间介绍不适用于代码

    <script type="text/javascript">
    //extending jQuery with ':random' selector, best put into separate plugin js file
    jQuery.jQueryRandom = 0;
    jQuery.extend(jQuery.expr[":"],
    {
        random: function(a, i, m, r) {
            if (i == 0) {
                jQuery.jQueryRandom = Math.floor(Math.random() * r.length);
            };
            return i == jQuery.jQueryRandom;
        }
    });        
    //end :random extend
$ (Function () { 
    var next = function ()
    {

    . $ ('# Slideshow img') not (': random') hide (). 
    setInterval (function () {
        $ ('# Slideshow img: visible') fadeOut ('slow').
        . Siblings ('img: random'). FadeIn ('slow')

    }, 10000);
    }
    next ();
    });
</script>

那“10000”没有用。请帮帮我

试试这个，

setInterval(function(){
randNum = getRandomInt(0, imgArray.length - 1);
nextBG = "url(" + imgArray[randNum] + ") no-repeat bottom center";
$('#slideshow img:first').attr("src", imgArray[randNum]);

}，10000）;
