sample javascript code for a popup saying, hello
Here's a sample JavaScript code that will display a popup saying "hello" when a button is clicked:
<!DOCTYPE html>
<html>
<head>
<title>Hello Popup</title>
</head>
<body>
<button onclick="showPopup()">Click me!</button>
<script>
function showPopup() {
alert("hello");
}
</script>
</body>
</html>
In this code, we have created a button element that will call the showPopup() function when clicked. The showPopup() function uses the alert() method to display a popup with the message "hello".
