Calling a function in parent file from child frame?
提问by David
I have a function that resizes the colwidth ratio of my framesetin "frame.html":
我有一个函数可以调整col我frameset在“frame.html”中的宽度比例：
<frameset id="set" cols="*,*" FRAMESPACING=0 BORDER=3 BORDERCOLOR=#eeeeee>
<frame src="index.html">
<frame src="index2.html">
<noframes></noframes>
</frameset>
The function works fine when called from "frame.html", However i want to call said function from the child file "index.html"... the function needs to remain in the parent file in order to run properly... How can I call my function in frame.htmlfrom index.html
从“frame.html”调用时该函数工作正常，但是我想从子文件“index.html”调用所述函数......该函数需要保留在父文件中才能正常运行......如何我可以调用我的函数frame.html吗index.html

Just try parent.functionName()it should work.
试一试parent.functionName()应该可以的。

Just to be sure that the scope is correct you should probably call window.parent.functionName()instead to be sure that it is actually the frames parent that is referenced
只是为了确保范围是正确的，您可能应该调用window.parent.functionName()以确保它实际上是引用的框架父级
