How to Determine the Button ID Upon Clicking

Determining the ID of a clicked button is essential for various interactive tasks. This concise guide will provide a detailed solution to this common programming scenario.

Consider the following HTML code:

<button>

To identify the ID of the clicked button, we need to modify the JavaScript function:

function reply_click(clicked_id) {
  // Access the ID of the clicked button
  alert(clicked_id);
}

In this revised function, we introduce the clicked_id parameter, which receives the ID of the button that triggers the function. Now, when any of the buttons is clicked, the reply_click() function will display the ID of that button as an alert message.

Therefore, when you click a button, the corresponding ID will be immediately available within the reply_click() function, allowing you to perform subsequent operations based on the specific button clicked.
