#36141 — Tell when external http resource loaded in frame.

I load an external synth script into a frame using windows open method  to load that frame. ***AFTER*** it is loaded "take a while" i would like to update some settings in the synth frame.

But is there a way for document, my frame "javascript" HTML DOM to know when the other frame finished loading?

If this Q is ment for others than yourself:
What the hell is a "synth frame"?
What the hell is a "synth script"?

> But is there a way for document, my frame "javascript" HTML DOM 

Is "document, my frame "javascript" HTML DOM" a document?
Where is that "document, my frame "javascript" HTML DOM"?

==========================

[All the above is not helpfull in your Q, methinks]

> to know

If the othe frame is in the same domain, you can access the same, imho:

let window2 = window.open("", "window2_name");
// later:
alert( "Done?: " + window2.innerHTML.length > 27 );
// [not tested]

It could send a message back if on common domain:

body.onload = "sendmessage()";

Or you could go fishing. 
I mean, you are not communicating, just thinking out loud.

====================

Modern javascript has all kinds of waiting-for-response mechanisms.

"I cannot get to town, because there are ten ways to get there?"

You can use the load event of iframe, as in:

  <iframe ... onload="alert(1)"></iframe>
