What is the best way to increment a variable by one when a button image is clicked?

Is there a way to increase a variable by +1 when clicking on an image button? ~John

Answer №1

Here is the code snippet that may help you with your query:

<html>
<body>
<button onclick="increaseCount()">INCREMENT</button><br/>
<button onclick="displayCount()">DISPLAY</button>
</body>

<script>
    var count = 0;
    function increaseCount(){
        count++;
    }

    function displayCount(){
        console.log(count);
    }
</script>
</html>

You can trigger a function through an onclick event to modify the value of a variable, as shown above.
