使用C＃中的代碼在按鈕單擊時創建Javascript警報

Question

我正在使用下面的代碼在后面的代碼中創建一個按鈕，並為該按鈕創建確認消息框。但是它不起作用，請幫助我創建此按鈕。

Button btn2 = new Button();
btn2.Attributes.Add(
    "OnClientClick", 
    "if (confirm(''Are you sure you want to add this estimate data?')) return;");

if(true) 
{
    //Do something
}

Answer 1

btn2.Attributes.Add("onclick", "javascript:return confirm('Are you sure you want to add this    estimate data??')"); 

Answer 2

您可以使用以下代碼：

btn2.Attributes.Add("onclick", "return confirm('Are you sure you want to add this estimate data?');")

Answer 3

您可以將ajaxcotoroll工具箱參考添加到您的網站，並為每個按鈕動態創建確認

Button btn2 = new Button();
btn.ID="buttonID";
ConfirmButtonExtender confirm = new ConfirmButtonExtender();
confirm.TargetControlID = "buttonID";
confirm.ConfirmText="Are you sure you want to add this    estimate data??'";

Answer 4

您還可以使用以下代碼：-

btn2.Attributes["onClick"] = "return confirm('Are you sure you want to add this   estimate data??');"

Answer 5

試試這個鱈魚：

 Button yourbtnid = new Button();
 yourbtnid.ID="Button1";
 ConfirmButtonExtender conf = new ConfirmButtonExtender();
 conf.TargetControlID = "Button1";
 conf.ConfirmText="Are you sure you want to add this    estimate data??'";

這是使用Ajaxcontroll調用的。

要么

Button yourbtnid = new Button();
yourbtnid.Attributes.Add(
     "OnClientClick", 
     "return confirm('Are you sure you want to add this    estimate data??');");
