8 minutes read

To set the focus to a div element in an iframe using JavaScript, you can first access the iframe using its ID or index, then access the contentDocument property of the iframe to get the document inside the iframe. From there, you can access the div element inside the document using getElementById or any other method to select the div element. Then, simply call the focus() method on the div element to set the focus to it. This will work as long as the iframe and the div element are in the same domain to avoid cross-origin security restrictions.

How can I change the focus to a div inside an iframe with JavaScript?

To change the focus to a specific div inside an iframe using JavaScript, you can use the following approach:

  1. Get a reference to the iframe element using its id or another selector.
  2. Access the content window of the iframe using the contentWindow property.
  3. Use the contentWindow property to access the document inside the iframe.
  4. Use the querySelector or getElementById method to select the specific div element inside the iframe.
  5. Call the focus method on the selected div element to change the focus to it.

// Get a reference to the iframe element
var iframe = document.getElementById('myIframe');

// Access the content window of the iframe
var iframeWindow = iframe.contentWindow;

var iframeDocument = iframeWindow.document;

// Select the specific div element inside the iframe
var divElement = iframeDocument.querySelector('#myDiv');

// Call the focus method on the div element to change the focus
divElement.focus();


In this example, replace 'myIframe' with the id of your iframe element and '#myDiv' with the selector or id of the div element inside the iframe that you want to focus on.
