例如url:

http://ip/abc?x=1&y=2

调用举例:

<!--

<script>

if(window.console) console.log(GetQueryString(‘x’));

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;
        }
</script>

-->
