iframe onload in IE7/8 with Javascript
提问by Chris Tonkinson
I have an iframe loading into a parent page. The iframe contains a sequence of forms, and I'd like to take action on the parent page every time the iframe content in reloaded (ie, after a form is submitted in the iframe content). The current code is located on the parent page and works in all the big players except IE (I'm only concerned with IE 7 & 8).
我有一个 iframe 加载到父页面中。iframe 包含一系列表单，每次重新加载 iframe 内容时（即，在 iframe 内容中提交表单之后），我都想在父页面上执行操作。当前代码位于父页面上，适用于除 IE 之外的所有大型播放器（我只关心 IE 7 和 8）。
var iframe = document.getElementById('theiframe');
function refresh( ) {
alert('foo');
}
if (iframe.attachEvent) iframe.attachEvent('onload', refresh);
else iframe.onload = refresh;
What am I missing that would prevent this from being effective in IE?
我错过了什么会阻止它在 IE 中有效？

Replace:
代替：
iframe.onload = refresh
with:
和：
iframe.attachEvent('load', refresh, false);
清除任何混淆：
var iframe = document.getElementById('theiframe');
function refresh( ) {
alert('foo');
}
if (iframe.attachEvent) iframe.attachEvent('onload', refresh);
else iframe.addEventListener('load', refresh, false)

You can call it from the iframeby calling parent.refresh()when you are done with a submit.
您可以在完成提交后iframe通过调用来调用它parent.refresh()。
