dynamically change onload for an iframe
提问by Sorin Buturugeanu
I have a page containing a couple of <iframe>tags. I want to change their onload actions dynamically. I have the following code that works fine in FF, Safari, Chrome, Opera, but IE (8) refuses to comply.
我有一个包含几个<iframe>标签的页面。我想动态更改它们的加载操作。我有以下代码在 FF、Safari、Chrome、Opera 中运行良好，但 IE (8) 拒绝遵守。
document.getElementById('myiframe').onload = function() {
return function() { file_onLoad(data); }
}();
I've been using something similar for setting the onchangeof an <input>element and this works well in all the browsers I've tested, including IE.
我已经使用设置类似的东西一直是onchange一个的<input>元素，这非常适用于所有我测试过的浏览器，包括IE浏览器。
document.getElementById('myinput').onchange = function() {
return function() { file_onChange(data); }
}();
So I guess it has something to do with the way I'm getting the frame element / object.
所以我想这与我获取框架元素/对象的方式有关。
I've also tried frames['myiframe']but with no success.
我也尝试过，frames['myiframe']但没有成功。
Thanks for your help!

It works fine on mine...
I tried:
它在我的工作正常......
我试过：
function whatever(){
document.getElementById('myiframe').src="http://www.google.com/"
document.getElementById('myiframe').onload = function() {
return function() { alert("Done."); }
}();
}
and it works. (I tried on IE9 with IE8 mode turned on)
If it does not work for you, try this:
它有效。（我在 IE8 模式下试过 IE9）
如果它不适合你，试试这个：
document.getElementById('myiframe').addEventListener('load', file_onLoad, false);
