单击确认消息框中的取消按钮后如何清除文本框？

Question

单击确认消息框中的取消按钮后，如何清除文本框。我的消息框脚本是（在Web应用程序中）。如果我们无法使用此脚本消息执行此操作，请再次提及。

 ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "confirm", "confirm('Do you want to delete it ..!!');", true);

Answer 1

confirm('Do you want to delete it ..!!')

根据您点击的按钮返回true or false ..

最好编写一个单独的函数并将其包含在JavaScript文件中并像上面那样调用..

否则你必须内联编写整个代码，但看起来很乱......

ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "confirm", "" +
    "document.body.onload = function(){"+
      "if(confirm('Do you want to delete it ..!!')==false)" +
        "{" +
           "document.getElementById('myTextBox').value='';" +
        "}"+
      "}", true);

Answer 2

   ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "confirm", "confirm('Do you want to delete it ..!!');", true) ? txtDate.text = string.Empty : txtdate1.text = string.Empty;
