我如何先顯示警告框，然后重定向到帶有查詢字符串的任何頁面？

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，我能夠顯示警告框，然后重定向到 test.aspx 頁面。

但是當我必須傳遞帶有地址的查詢字符串時，問題就來了：

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);

提前致謝

Answer 1

您的代碼有不必要的 (') s，它會破壞 javascript 中的字符串。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);
