Why Aren't My Inline onclick Events Working in My Chrome/Firefox Extension?

Onclick Event Not Working in Chrome/Firefox Extension

Inline JavaScript, commonly used in HTML documents, allows the execution of scripts upon user interactions like button clicks. However, this approach faces limitations in Chrome and Firefox extensions due to security and performance considerations.

Cause:

Chrome Extensions and Firefox WebExtensions prohibit inline JavaScript to enhance security and prevent potential vulnerabilities.

Solution:

To resolve this issue, you must use event listeners to bind onclick events to specific elements. Here's the modified code:

popup.js:

document.addEventListener('DOMContentLoaded', function() {
  var link = document.getElementById('link');

  link.addEventListener('click', function() {
    hellYeah('xxx');
  });
});

popup.html:

<a>

Explanation:

• Assign an ID to the link, e.g., "link."
• In the popup.js file, use document.addEventListener('click', ...) to listen for onclick events on that specific link.
• The callback function executes the hellYeah('xxx') logic when the link is clicked.
• Ensure that popup.js is loaded as a separate script file in popup.html.

By employing this method, you can bind onclick events to elements within Chrome and Firefox extensions, ensuring their functionality without compromising security.
