获取URL的name值 getUrl(url,name) 传入url和key 得到key对应的value

<body>
        <script type="text/javascript">
            var url = "http://192.168.1.82:8020/juzhong/getURLvalue.html?name1=zhangyiggg&sex1=nuuu&age1=8090";
            var name1 = getUrl(url,"name1");
            var sex1 = getUrl(url,"sex1");
            var age1 = getUrl(url,"age1");
            console.log("name1= "+name1);
            console.log("sex1= "+sex1);            
            console.log("age1= "+age1);
            //链接带后缀！用
            function getUrl(url,name) {
                var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)");
                var r = url.split("?")[1].match(reg);
                //    var r = url.split(name+"=")[1].split("!")[0];
                if (r != null)
                    return decodeURI(r[2]);
                return null;
            }
        </script>
    </body>
