How to Access the Parent Iframe from JavaScript?

Accessing Parent Iframe from JavaScript

When working with multiple Iframes on the same domain, it becomes essential to access information from the parent Iframe to facilitate seamless communication and control. Here's how you can achieve this:

<iframe>

In the parent page, assign a unique name to the iframe.

parent.document.getElementById(window.name);

On the child page, use the above code to access the parent Iframe object. This approach allows you to establish a direct reference to the parent Iframe from the child page.

Additional Notes:

• Use the same name and ID for the iframe to simplify access.
• If there are multiple Iframes with the same page, you can maintain an array of references to distinguish them.
• This technique is especially useful when you need to close specific Iframes dynamically from the child page.
