使用Javascript在弹出网页上单击x按钮时如何处理？
我在插件中有一个继承自 System.Web.UI.Page 的“弹出”网页，该插件是大型 Web 框架的一部分。标记位于下面的 window.beforeunload 和 window.onclose，它不起作用。当我打开网页并单击“关闭”(_close) 按钮时，会弹出“Hello World”。 当单击“_close”按钮时，如何以相同的方式处理“x”上的单击？
<script language="javascript">
function doClose() { alert('Hello World!'); } window.onload = doClose(); // also tried with window.beforeunload </script>
I have a “pop-up” web page inherits from System.Web.UI.Page in a plug-in which is a part of a large web framework. The markup is inside <asp:Content> below. I need to perform some actions (updating the page behind) when the user clicks on “Close” button (id = _close) and when the user clicks on the ‘x’ button on the right corner of the page. My page is not displayed in the browser. I got the “onclick” (in the code behind) to work for “Close” button below, but I don’t know how to detect when the ‘x’ button is clicked. I tried on window.beforeunload and window.onclose, it doesn’t work. “Hello World” pops up when my web page opens and when I click “Close” (_close) button.
How do I handle for the click on the ‘x’ the same way when “_close” button is clicked?
<script language="javascript">
function doClose() { alert('Hello World!'); } window.onload = doClose(); // also tried with window.beforeunload </script>

您可以在开启器上执行代码。在opener中编写一个方法并从弹出窗口中执行它。

You can execute the code on the opener. Write a method in opener and execute it from the pop-up window.
