System.Web.UI.ScriptManager.RegisterClientScriptBlock運行兩次

Question

我正在註冊一個腳本塊的按鈕單擊。但是，當我做一個刷新幀腳本再次運行。有沒有辦法來解決這個問題？

感謝

你檢查，看看它是否已註冊？

RegisterClientScriptBlock

String csName = "ButtonClickScript"; 
    Type csType = this.GetType(); 

    // Get a ClientScriptManager reference from the Page class. 
    ClientScriptManager cs = Page.ClientScript; 

    // Check to see if the client script is already registered. 
    if (!cs.IsClientScriptBlockRegistered(csType, csName)) 
    { 
     StringBuilder csText = new StringBuilder(); 
     csText.Append("<script type=\"text/javascript\"> function DoClick() {"); 
     csText.Append("Form1.Message.value='Text from client script.'} </"); 
     csText.Append("script>"); 
     cs.RegisterClientScriptBlock(csType, csName, csText.ToString()); 
    }
