How to Access IFRAME Data After it has Loaded?

Accessing IFRAME Data Post-Loading

When an IFRAME is inserted into a web page, executing a callback upon completion of its loading process can be essential. However, external control over the IFRAME's content can present a challenge.

Solution: Utilize a Timeout

The solution lies in employing a timeout function. Here's an example implementation using jQuery:

<code class="javascript">$('#myUniqueID').load(function () {
  if (typeof callback == 'function') {
    callback($('body', this.contentWindow.document).html());
  }
  setTimeout(function () { $('#frameId').remove(); }, 50);
});
</code>

Implementation Details:

• When the IFRAME's loading is complete, the callback function is executed.
• The IFRAME's content is accessed via its contentWindow and HTML code is retrieved.
• After executing the callback, a timeout is set to remove the IFRAME to prevent it from remaining in the DOM.

Considerations:

• If the IFRAME's URL resides on your domain, this method will allow access to its content.
• For cross-site requests, content access may be restricted due to cross-origin policy limitations.
