JS获取URL的值 - 爱码网

假设当前页面URL为：http://localhost:30641/test/Default2.aspx?id=A

利用JS获取这个A，(strid就是A)

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>

    <script type="text/JavaScript">
        function Getid() {
            var url = location.search;
            var strid;
            if (url.indexOf("?") != -1) {

                strid = url.substr(url.indexOf("?") + 4, url.indexOf("&") - url.indexOf("?") - 4);
            }

            window.location.href = "Default.aspx?id=" + strid;
        }
 
    </script>
</head>
<body>
    <form >
    <div>
        <a href="javascript:Getid();">打开新页面，传递ID为A的</a>
