一个js获取url参数的例子，贴一贴

<script type="text/javascript">
 //获取Url地址参数，调用方式如下
 //var req = RequetParame(window.location);
 //alert(req.id);
 //alert(req.aa);

function RequetParame(_url) {
    var url = _url.search.replace("?", "").replace(/=/ig, ":");
    var s = url.split("&");
    var info = "{";
    for (var i = 0; i < s.length; i++) {
        info += '"' + s[i].split(":")[0] + '"' + ":" + '"' + s[i].split(":")[1] + '"' + ",";
    }
    info = info.substring(0, info.length - 1);
    info += "}";
    var info = eval("(" + info + ")");
    return info;
}

 var req = RequetParame(window.location);
 alert(req.id);
 alert(req.aa);
</script>
