我该怎么办?

I have a textbox that will take the employee number.
When the curser out (mouseout) from this textbox I want the name of this employee to appear in another textbox.

推荐答案

您为此使用了错误的事件.正确的选择是TextChanged或LostFocus.您只需处理这些事件之一，然后启动填写其他TextBox所需的代码.

You''re using the wrong event for this. The correct choices would be either TextChanged or LostFocus. You just handle one of those events and kick off the code you need to to fill in the other TextBox.

输入文本时，我总是将鼠标光标移开，所以这是一个糟糕的设计.仅当当前控件失去焦点(或按下按钮)时，才应更新其他控件，因此此时，您将需要处理LostFocus事件或Leave事件.

I always move the mous cursor out of the way when I''m entering text, so that''s a bad design. You should only update other controls when the current control looses focus (or a button is pushed), so at that point, you''d need to handle either the LostFocus event, or the Leave event.

您可以使用JavaScript处理文本框的mouseout事件，然后提取值并用它填充另一个文本框. jQuery将使其中的一些操作变得更容易.

You can use JavaScript to handle the mouseout event for the textbox then extract the value and populate the other textbox with it. JQuery will make some of this easier.
