firefox中iframe改变父窗口url,document.write会失效?
两个页面,a.html:
<html>
<body>
<script>document.write('asdfasdfasfd')</script>
<a href="a.html" >go</a>
<iframe src="b.html" width=400px height=300px ></iframe>
</body>
</html>
b.html:
<html>
<body>
<a href=a.html target=_top >go</a>
</body>
</html>
在IE中正常,firefox中会出现document has no properties的错误
