<script>
var G = function (id) {return document.getElementById(id); }
var C = function (tag) {return document.createElement(tag); }
window.onload = function ()
{
var f = C('frame');
f.name = 'my';
f.id = 'my';
f.src = 'about:blank';
G('content').appendChild(f);
alert('test');
window.frames['my'].document.write('Loading...');
}
</script>
<frameset id="content" rows="100%,*" cols="*" frameborder="no" border="0" framespacing="0">
</frameset>
</html>
alert（'test'）; //删除此行，Opera加载不成功。
为什么？ IE浏览器Chrome浏览器没有问题......
alert('test'); // Remove this line, Opera load is not successful. why? IE Firefox Chrome Safari No problem...
推荐答案
是的，另一个关于：空白加载计时问题..这真的很难搞定这个权利： http://hsivonen.iki.fi/about-blank/
Yay, another about:blank load timing problem.. It's really hard to get this right: http://hsivonen.iki.fi/about-blank/
无论如何，当Opera做一个像这样的简单事情时，与其他人不一样，根据定义，它是Opera中的一个错误。我已经报告过CORE-45144 - 当FRAME通过DOM（appendChild和朋友）附加到FRAMESET时，不会立即更新window.frames集合，因此应该在适当的时候修复它。有一个正在进行的维护项目可以解决这个问题，结果不会成为Opera 12，但很可能是下一个重大更新。
Anyway, when Opera does a simple thing like this differently from everybody else it's by definition a bug in Opera. I have reported "CORE-45144 - window.frames collection not immediately updated when FRAME is appended to FRAMESET through DOM (appendChild and friends)" so it should be fixed in due course. There is an on-going maintenance project that might solve this issue among others, results won't make it for Opera 12 but quite likely the next majorish update.
如果你需要一个解决方法，只需使用带有一些小超时值的setTimeout（）来延迟稍微写入新帧的代码。
If you need a workaround, just use setTimeout() with some small timeout value to delay the code that writes to the new frame slightly.
