js获取url参数值

用过的封装好的js获取url问号后的参数的方法：

<script>

var Request = new Object();

Request = GetRequest();
var error;
error = Request['error'];  
function GetRequest() {
    var url = location.search; //获取url中"?"符后的字串
    var theRequest = new Object();
    if (url.indexOf("?") != -1) {
        var str = url.substr(1);
        strs = str.split("&");
        for(var i = 0; i < strs.length; i ++) {
            theRequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]);
        }
    }
    return theRequest;
}

</script>
