A question about the iframe framework, please ask an expert to answer it_html/css_WEB-ITnose

This is the code for the frame part of my iframe








top.html There are two links A and B

Now I want to implement such a function. When A is clicked, the left and right below are displayed normally (that is, divided into left and right part), how to realize that when you click B, the left and right parts below are merged, that is, the bottom part is a whole, and the parts are left and right~~~~~~~~~

Idea: When you click A, you don’t need to execute too many methods, just keep the original frame mode. If you want If you want to change it, get the cols of the frameset and change its layout mode.

When clicking B, get the cols of the frameset inside and set the value to "*"
