推荐答案

的GotFocus，引发LostFocus事件文本框在Windows控制但器WebControls，你不会得到这些，而不是你应该尝试客户方脚本（JavaScript）的。

GotFocus, LostFocus events for TextBox are in Windows Control but for WebControls, You will not get these, Instead of you should try clientside scripting (Javascript).

在JavaScript的你会得到事件聚焦和模糊的文本框（这实际上是一种输入类型网页=文本），你可以使用这些为你的目的。

In javascript you will get the event focus and blur for a textbox (which is actually a input type="text" on web page) , and you can use these for your purpose.

有关设置事件处理程序，使用上+事件作为事件处理程序，并提供JS code要执行。

For setting an event handler, use on + event as event handler and provide the js code which to execute.

像模糊的情况下，您应该添加属性的onblur 和重点添加属性的onfocus

like for blur event you should add attribute onblur and for focus add attribute onfocus

在Javascript中你可以试试，如果你的aspx有文本框为

In Javascript you can try, if your aspx has TextBox as

<asp:TextBox runat="server" id="textbox1" onblur="SetTextInTextBox2()" />
<asp:TextBox runat="server" id="textbox2" onfocus="SetTextInTextBox2()" />

在JavaScript

in javascript

function SetTextInTextBox2()
{
    document.getElementById('textbox2').value = document.getElementById('textbox1').value;
}
