问题描述
此代码将在弹出窗口中打开go.com:
This code will open go.com in popup window:
<a href="javascript:void(0)" onClick="javascript:window.open('http://go.com','','status=yes,scrollbars=yes,toolbar=no,menubar=no,location=no ,width=300px,height=300px')">open</a>
,并且我想在主页中使用alert('closed!')
,当弹出窗口关闭且我无法编辑使用onunload="alert('closed!')"
的弹出页面时,因为弹出页面是外部页面,并且我无法更改代码,例如
and I want to use alert('closed!')
in main page, when popup is closed and I can't edit popup page for use onunload="alert('closed!')"
, because the popup page is an external page and I can't change the code like
var mywindow = window.open('http://go.com') ...
谢谢.
推荐答案
如何打开包含包含外部页面内容的iframe的本地"窗口,而不是直接在窗口中加载该外部页面?这样,您仍然可以对实际窗口进行足够的控制,以知道何时关闭窗口.
How about instead of directly loading that external page in the window, you open up a "local" window with an iframe containing the external page content? That way you still have enough control over the actual window to be able to tell when it's closed.
某些缺点:地址栏不会显示他们正在浏览的URL,如果go.com具有某种框架破坏代码,它也可能会损坏.
Some drawbacks: the address bar will not show the URL they are browsing and it may also break if go.com has some sort of frame busting code.
一些示例代码:
function openIFrameInWindow(url) {
var myWindow = window.open("");
var iframe = document.createElement("iframe");
iframe.src = url;
myWindow.document.body.appendChild(iframe);
myWindow.document.body.onbeforeunload = function () { alert("WINDOW CLOSED") };
}
<a href="javascript:void(0)" onClick="javascript:openIFrameInWindow('http://go.com')">open</a>
