The webpage contains iframe. after js changes location. href, the progress bar keeps loading. How to solve

The webpage contains iframe. after js changes location. href, the progress bar keeps loading. A.htm & lt; iframename = win1width = 100 height = 100 & gt; & lt;/iframe & gt; & lt; script & gt; win1.location. the href webpage contains iframe, and js changes location. the progress bar is always loaded after href.
A.htm


Script
Win1.location. href = "abc. php"
Script


Result a.htm is always loaded. The actual program is running.

And it's okay to run abc. php directly.




------ Solution --------------------
You must have a problem. I just tried it. it's okay. after running, the progress bar shows that it has been completed (I used IE7 ), it may be your abc. php has a judgment statement or something? Paste abc. php to see it.

I don't know why !~
------ Solution --------------------
Currently, browsers are not very friendly to iframe, so try to use iframe as few as possible.
