To disable a button after one click, use the following JavaScript: `button.onclick = function() { this.disabled = true; };` This ensures the button becomes inactive after it's clicked once. For example, in HTML: `<button id='myButton'>Click me</button>` with JavaScript: `document.getElementById('myButton').onclick = function() { this.disabled = true; };`. This is useful to prevent multiple submissions.
