Handling event part 2

Handling Events

Let's display an alert popup when the user clicks a specified button:

<button onclick="show()">Click Me</button>
<script>
function show() {
alert("Hi there");
}
</script>Try It Yourself

Event handlers can be assigned to elements.
For example:

var x = document.getElementById("demo");
x.onclick = function () {
document.body.innerHTML = Date();
}Try It Yourself

You can attach events to almost all HTML elements.
