<body>

浏览器中输入 http://localhost/test/js_url.php?a1=aaa&a2=bbb&a3=ccc

会依次弹出aaa，bbb，ccc

<script type="text/javascript">

//方法一

function GetQueryString(name)

{

     var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)");

     var r = window.location.search.substr(1).match(reg);

     if(r!=null)return  unescape(r[2]); return null;

}

// 调用方法

alert(GetQueryString("a1"));

alert(GetQueryString("a2"));

//方法二

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;

}

var Request = new Object();

Request = GetRequest();

alert(Request['a3']);

</script>
