Onclick in JAVASCRIPT

The onclick event in JavaScript is used to execute a function when an element is clicked.It is one of the simplest ways to handle click events in HTML and JavaScript

1. Inline HTML

<button onclick="alert('Button clicked!')">Click Me</button>

• The function runs directly when the button is clicked.

1. Assigning in JavaScript

<button id="myBtn">Click Me</button>

<script>
  document.getElementById("myBtn").onclick = function() {
    alert("Button clicked using JavaScript!");
  };
</script>

• Here we assign an event handler to the element.

1. Calling a Function

<button onclick="sayHello()">Click Me</button>

<script>
  function sayHello() {
    alert("Hello, welcome!");
  }
</script>

• The button calls a predefined function.
