The source of the iframe is loaded dynamically after user interaction. I need to trigger a JS function once the iframe is fully loaded. Afaik, the common way to do it is to use the onload event of the iframe. I tried as below, and also in a JS block, but with no luck. It never seems to trigger the onload after the content of the iframe is loaded.

I had a script in the head tag with functions to draw a table then load it with data using a different function. The body used onload to call the draw table function. When I moved the draw table function to a script inside the body and let that run on its own (without having to call a function) then everything seemed to work perfectly fine.
It is as follows It might not be obvious but your issue is caused by the following line plane. onload drawImage (context); If written that way, it simply doesnt do what you might think.
