如何首先顯示警報框，然後使用查詢字符串重定向到任何頁面？

Question

ScriptManager.RegisterStartupScript(UpdatePanel2, this.GetType(), "click", "alert('This Email address is already registered...');window.location.href ='test.aspx'", true); 

通過使用上面的代碼，我能夠顯示警報框，然後重定向到test.aspx頁面。

但是問題來了，當我不得不與像轉交地址查詢字符串：

ScriptManager.RegisterStartupScript(UpdatePanel2, this.GetType(), "click", "alert('This Email address is already registered...');window.location.href ='test.aspx?WidgetID='" + Request.QueryString["WidgetID"] + "'&lan='" + readCookie() + "'&seeHome=true'", true); 

在此先感謝

您的代碼不必要（'） S的突破在JavaScript字符串。試試這個

ScriptManager.RegisterStartupScript(UpdatePanel2, this.GetType(), "click", "alert('This Email address is already registered...');window.location.href ='test.aspx?WidgetID=" + Request.QueryString["WidgetID"] + "&lan=" + readCookie() + "&seeHome=true'", true);
