Table of Contents
HTML Code
HTML Code is given below, we have two button tags with onclick attribute and an input field to display the counter value.
<!DOCTYPE html>
<html lang="en">
<head>
<title>Simple Click Counter using JavaScript</title>
</head>
<body>
<h1>Counter</h1>
<input type="number" value="0" id="count">
<button onclick="count()">Click Me</button>
<button onclick="reset()">Reset</button>
</body>
</html>
JavaScript Code
Take a look at the JavaScript code given below.
<script>
var x =0;
function count(){
x=x+1;
document.getElementById('count').value=x;
}
function reset(){
x=0;
document.getElementById('count').value=x;
}
</script>
On counter button click, count() function will be called and the current value will be incremented by 1 using + operator and then the new value will be displayed using .value property.
On reset button click, reset() function will be called and value of variable x will be reset to 0 and it will also be displayed using .value property.
