Automatically triggering a button click within an iframe upon loading

I have set up an iframe with a website inside that contains a button which I would like to automatically click when the iframe is loaded. The HTML code for this button is as follows:

<div class="buttonnext action-button-container">
        <button type="button" id="nextBtn" class="action-button red0">
          <span id="nextBtn-final">
            CLICK TO PROCEED
          </span>
        </button>
</div>

Answer №1

 /* Here is a suggestion on how to achieve this task:
    
     1. Locate the Iframe element
     2. Access the content window object and navigate through the DOM to find your button.
     3. Trigger the event once you've located the button.
*/    
        var iframe = document.getElementById("iframe");
        var btnElement = iframe.contentWindow.document.getElementsById("nextBtn");
        btnElement.click();
