Can be solved by anchor point

Click the button onclick="window.frames[0].location.href='index.htm#ff'"

You can also use scripts

Thank you for your answer. The requirements now are a little different, main. The iframe in htm loads different pages at different times, such as a.htm, b.htm, c.htm, etc. Can my COMMAND button in main.htm directly find different pages according to the different pages loaded? What about an element with ID FF and navigating to that location? Thanks for answering again!

Make it clearer, but it’s not too clear.
