按下TAB键时如何触发事件?

问题描述：

我只想在某些用户按文本框中的TAB键时捕获".我正在一个简单的CRUD asp.net应用程序中工作，c#作为后面的代码.

I just want to "catch" when some user press the TAB key in a Textbox. I'm working in a simple CRUD asp.net application, c# as code behind.

我尝试以此作为测试:

private void KeyForm_KeyDown( object sender, KeyEventArgs e )
      {
         keyInfoLabel.Text =
            "KeyCode: " + e.KeyCode + '\n' +
            "KeyData: " + e.KeyData + '\n' +
            "KeyValue: " + e.KeyValue;
      }

但是它仅适用于C#桌面应用程序.

But it just works with C# desktop application.

答

$(document).ready(function () {
    $('#<%= testTextBox.ClientID%>').keydown(function (e) {
       var code = (e.keyCode ? e.keyCode : e.which);
           if (code == 9) {
             $('#<%= 2ndTextBox.ClientID%>').focus()
                return false;
             }
    });
});

对某人有用.
