There is an url www.example.com/page-1.php. This page has a function called make_circle. Used like this: make_circle('10');

When I visit www.example.com/page-2.php, I want it to run make_circle('10'); on www.example.com/page-1.php. Is this possible?

On www.example.com/page-2.php:

<iframe id="coolpage" src="www.example.com/page-1.php" style="width:100px;height:100px;border:0; border:none;"></iframe>
<!-- How do I run the make_circle function on page-1 while I am on page-2 -->

  • @epascarello `document.getElementById('targetFrame').contentWindow.targetFunction();` What is the `targetFrame` id? is it the id in the iframe? In my case its called `coolpage` – Kiwa Feb 07 '19 at 00:13
  • @Kiwa: Yes. But how you get a reference to the iframe element doesn't matter. This is just an example. – Felix Kling Feb 07 '19 at 00:14
