How to catch an exception thrown from inside an iframe?

@cali_green 

To catch an exception thrown from inside an iframe, you can use a try-catch block in the parent window that contains the iframe. Here's an example:

1
2
3
4
5
6
7
8

try {
  var iframe = document.getElementById('myIframe');
  var iframeWindow = iframe.contentWindow;

  iframeWindow.myFunctionThatThrowsError();
} catch (error) {
  console.error('An error occurred inside the iframe:', error);
}

In this example, we are trying to call a function myFunctionThatThrowsError() from inside the iframe. If an exception is thrown inside the iframe, it will be caught by the parent window's try-catch block and you can handle it accordingly.

Make sure to replace 'myIframe' with the id of your iframe element, and 'myFunctionThatThrowsError()' with the actual function that may throw an exception inside the iframe.
