How to access elements inside an iframe?

@deron 

To access elements inside an iframe, you can use the contentWindow property of the iframe element to get the window object of the iframe document. Then, you can use standard DOM manipulation methods to access and manipulate elements inside the iframe.

Here is an example code snippet to access an element inside an iframe with id "myFrame":

var iframe = document.getElementById('myFrame');
var iframeWindow = iframe.contentWindow;
var iframeDocument = iframeWindow.document;
var elementInsideIframe = iframeDocument.getElementById('elementIdInsideIframe');

// Now you can access and manipulate the elementInsideIframe
elementInsideIframe.innerHTML = 'Hello from outside the iframe!';

Make sure that the iframe and the parent document are on the same domain, otherwise you may run into cross-origin security restrictions.
