To open a popup on a button click in JavaScript, use the `window.open()` function. First, ensure your button has an `id` attribute for easy reference. Then, add an event listener to this button: `document.getElementById('yourButtonId').addEventListener('click', function() { window.open('yourPopupURL', 'Popup Title', 'width=600,height=400'); })`. Replace `'yourButtonId'` with the actual ID of your button and `'yourPopupURL'` with the URL you wish to open in the popup. This approach allows you to create interactive web pages with popups that enhance user engagement.
