帶有重定向的JavaScript警報背後的代碼

Question

當我重定向到另一個頁面後，如何使我的JavaScript在代碼中工作？我有一個asp按鈕控件，當我點擊那個按鈕，我想要提醒，然後導航到另一個頁面。當我在我的代碼中（在JS代碼之前或之後）有一個Response.Redirect時，8次嘗試都不起作用。當我評論重定向出來時，一些（2,7 & 8）工作。

//Try one 
ScriptManager.RegisterStartupScript(this, GetType(), "test", "alert('test1');", true); 

//Try two 
ClientScript.RegisterClientScriptBlock(typeof(Page), "test", "test2"); 

//Try three 
Page.ClientScript.RegisterStartupScript(this.GetType(), "CallMyFunction", "alertMessage()", true); 

//Try four 
ClientScript.RegisterStartupScript(GetType(), "CallMyFunction", "alertMessage()", true); 

//Try five 
ClientScript.RegisterStartupScript(GetType(), "CallMyFunction", "javascript: alertMessage(); ", true); 

//Try six 
ClientScript.RegisterClientScriptBlock(GetType(), "CallMyFunction", "<script>alert('test4')</script>"); 

//Try seven 
Response.Write("<script>alert('test5');</script>"); 

//Try eight 
string script = "alert('test6')"; 
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "CallMyString", script, true); 

response.redirect("pageUrlHere"); 
//With this code above, none of the js functions (alerts) work 

//response.redirect("pageUrlHere"); 
//With this commented out, try 2, 7 and 8 work. 

JS功能：

function alertMessage() { 
    alert('test3'); 
} 

Answer 1

你可以嘗試以下方法：

ScriptManager.RegisterStartupScript(this,this.GetType(),"redirect", 
"alert('test 9'); window.location='" + 
Request.ApplicationPath + "/anotherpage.aspx';",true);

試試這個它會顯示警告和導航 這使它在單獨的方法，只是再次重複使用。

public void ShowAlertAndNavigate(string msg , string destination) 
    { 
     string alert_redirect_Script = string.Format(@"<script type=""text/javascript""> 
             alert('{0}'); 
             window.location.href = destination; 
             </script>", msg); 
     ClientScript.RegisterClientScriptBlock(this.GetType(), "alertredirectscript", alert_redirect_Script, false); 
    }
