如果你不想只使用jQuery核心功能来动画你的背景，试试这个:

jQuery(".usercontent").mouseover(function() {
      jQuery(".usercontent").animate({backgroundColor:'red'}, 'fast', 'linear', function() {
            jQuery(this).animate({
                backgroundColor: 'white'
            }, 'normal', 'linear', function() {
                jQuery(this).css({'background':'none', backgroundColor : ''});
            });
        });

我喜欢使用delay()来完成这个任务，这里有一个例子:

jQuery(element).animate({ backgroundColor: "#FCFCD8" },1).delay(1000).animate({ backgroundColor: "#EFEAEA" }, 1500);

这可以由函数调用，“element”是元素类/名称/等。元素将立即以#FCFCD8背景出现，稍等片刻，然后淡出为#EFEAEA。

这些天jQuery颜色插件支持以下命名颜色:

aqua:[0,255,255],
azure:[240,255,255],
beige:[245,245,220],
black:[0,0,0],
blue:[0,0,255],
brown:[165,42,42],
cyan:[0,255,255],
darkblue:[0,0,139],
darkcyan:[0,139,139],
darkgrey:[169,169,169],
darkgreen:[0,100,0],
darkkhaki:[189,183,107],
darkmagenta:[139,0,139],
darkolivegreen:[85,107,47],
darkorange:[255,140,0],
darkorchid:[153,50,204],
darkred:[139,0,0],
darksalmon:[233,150,122],
darkviolet:[148,0,211],
fuchsia:[255,0,255],
gold:[255,215,0],
green:[0,128,0],
indigo:[75,0,130],
khaki:[240,230,140],
lightblue:[173,216,230],
lightcyan:[224,255,255],
lightgreen:[144,238,144],
lightgrey:[211,211,211],
lightpink:[255,182,193],
lightyellow:[255,255,224],
lime:[0,255,0],
magenta:[255,0,255],
maroon:[128,0,0],
navy:[0,0,128],
olive:[128,128,0],
orange:[255,165,0],
pink:[255,192,203],
purple:[128,0,128],
violet:[128,0,128],
red:[255,0,0],
silver:[192,192,192],
white:[255,255,255],
yellow:[255,255,0]

试着使用它

-moz-transition: background .2s linear;
-webkit-transition: background .2s linear;
-o-transition: background .2s linear;
transition: background .2s linear;

我也有同样的问题，并通过包含jQuery UI来修复它。以下是完整的脚本:

<!-- include Google's AJAX API loader -->
<script src="http://www.google.com/jsapi"></script>
<!-- load JQuery and UI from Google (need to use UI to animate colors) -->
<script type="text/javascript">
google.load("jqueryui", "1.5.2");
</script>


<script type="text/javascript">
$(document).ready(function() {
$('#menu ul li.item').hover(
    function() {
        $(this).stop().animate({backgroundColor:'#4E1402'}, 300);
        }, function () {
        $(this).stop().animate({backgroundColor:'#943D20'}, 100);
    });
});
</script>

使用CSS3-Transitions。支持很棒(所有现代浏览器，甚至IE)。使用Compass和SASS可以很快完成:

#foo {background:red; @include transition(background 1s)}
#foo:hover {background:yellow}

纯CSS:

#foo {
background:red;
-webkit-transition:background 1s;
-moz-transition:background 1s;
-o-transition:background 1s;
transition:background 1s
}
#foo:hover {background:yellow}
