url字符串编码乱码问题

 function webChart() {
            var t = document.getElementById("txtReceive");
            if (t.value == null || t.value == "") {
                alert("请先进行查询");
            }
            else {
              
                alert(t.value);
                document.getElementById("center-iframe").src = "map/industryMap.aspx?_indeustry=" + t.value;
}}

这个时候alert出来的编码很正常，都是汉字。

但是在后台获取时已经乱码

        protected void Page_Load(object sender, EventArgs e)
        {
            Industry = Request.QueryString["_indeustry"].ToString();

            InitMap();
            getShowMuilt();
        }

web.config已经配置为UTF-8 但是还是不行

<system.web>
    <globalization culture="en-US" uiCulture="en" requestEncoding="UTF-8"
                   responseEncoding="UTF-8" fileEncoding="UTF-8" />
  </system.web>

最终解决方案

 function webChart() {
            var t = document.getElementById("txtReceive");
            if (t.value == null || t.value == "") {
                alert("请先进行查询");
            }
            else {
                var url = encodeURI("map/industryMap.aspx?_indeustry=" + t.value);
                alert(url);
                document.getElementById("center-iframe").src = url;
}
}

结果如下：
