使用Javascript在IE7 / 8中加载iframe [英] iframe onload in IE7/8 with Javascript

问题描述

我将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），我都希望在父页面上执行操作。当前代码位于父页面上，适用于IE以外的所有大型播放器（我只关注IE 7和8）。

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).

var iframe = document.getElementById('theiframe');
function refresh( ) {
  alert('foo');
}
if (iframe.attachEvent) iframe.attachEvent('onload', refresh);
else iframe.onload = refresh;

我错过了哪些会阻止它在IE中有效？

What am I missing that would prevent this from being effective in IE?

推荐答案

替换：

iframe.onload = refresh

with：

iframe.attachEvent('load', refresh, false);

To clear any confusion:

var iframe = document.getElementById('theiframe');
function refresh( ) {
  alert('foo');
}

if (iframe.attachEvent) iframe.attachEvent('onload', refresh);
else iframe.addEventListener('load', refresh, false)
