asp.net中url字符串編碼亂碼的原因與解決方法

先看實例
復制代碼 代碼如下:
 function webChart() {
            var t = document.getElementById("txtReceive");
            if (t.value == null || t.value == "") {
                alert("請先進行查詢");
            }
            else {

                alert(t.value);
                document.getElementById("center-iframe").src = "map/industryMap.aspx?_indeustry=" + t.value;
}}

這個時候alert出來的編碼很正常，都是漢字。

但是在後台獲取時已經亂碼

復制代碼 代碼如下:
        protected void Page_Load(object sender, EventArgs e)
        {
            Industry = Request.QueryString["_indeustry"].ToString();

            InitMap();
            getShowMuilt();
        }

web.config已經配置為UTF-8 但是還是不行
復制代碼 代碼如下:
<system.web>
    <globalization culture="en-US" uiCulture="en" requestEncoding="UTF-8"
                   responseEncoding="UTF-8" fileEncoding="UTF-8" />
  </system.web>

最終解決方案

復制代碼 代碼如下:
 function webChart() {
            var t = document.getElementById("txtReceive");
            if (t.value == null || t.value == "") {
                alert("請先進行查詢");
            }
            else {
                var url = encodeURI("map/industryMap.aspx?_indeustry=" + t.value);
                alert(url);
                document.getElementById("center-iframe").src = url;
}
}
