基于jQuery实现仿搜狐辩论投票动画代码(附源码下载)

<script type="text/javascript">
$(document).ready(function () {
var a = 500;
var b = 130;
$("#white").animate({ width: 0, left: "250px" }, 1000, function () {
$("#vs").fadeIn("slow", function () {
$("#all").html(a + b); $("#aa").html(a); $("#bb").html(b);
var newLeft = a / (a + b) * 500 - 20 + "px"; //20为vs 的一半
$("#vs").animate({ left: newLeft }, 1000);
$("#red").animate({ width: newLeft }, 1000);
});
});
});
</script>
