How Do I Identify the ID of a Clicked Button in JavaScript?

Identifying the Clicked Button's ID

In HTML and JavaScript, you can utilize the onClick event to handle user interaction with buttons. A common scenario is to identify the specific button that triggered the event, which requires retrieving its ID.

To do this, you can pass the ID of the clicked button as a parameter to the event handler function. Here's how to implement it:

1. Assign unique IDs to each button:

<button>

2. In the event handler function, access the this keyword, which represents the DOM element that triggered the event:

function handleButtonClick(clickedButtonId) {
  // Perform actions based on the clicked button's ID
  alert(clickedButtonId);
}

In this example, the handleButtonClick function receives the clicked button's ID as a parameter, allowing you to perform specific operations depending on which button was clicked.
