A very simplistic solution would look something like this: 

<!DOCTYPE html>
<html>
<body>

Checkbox: <input type="checkbox" id="m1" value="1" onclick="myFunction('m1')">

Checkbox: <input type="checkbox" id="m2" value="2" onclick="myFunction('m2')">

Checkbox: <input type="checkbox" id="m3" value="3" onclick="myFunction('m3')">

<p>Click the "Try it" button to display the value of the value attribute of the checkbox.</p>
 
<p id="demo"></p>

<script>
function myFunction(id) {
    var x = document.getElementById(id).value;
    document.getElementById("demo").innerHTML = x;
}
</script>

</body>
</html>
