  • Looking at the image and taking it as an example, I assume that you want to associate a number with each checkbox so that when you press Compare, the program knows what to compare with the clicked checkboxes. Correct?

  • your checkbox looks like this: Checkbox: <input type="checkbox" id="myCheck" value="myvalue">. assigns a value for each value

  • It’s not that the checkbox side had an input number and I took it out, and I wanted every click I give in the checkbox to be equivalent to a number in the input number @Israelzebulon

  • takes this answer code and implements it within myFunction()

  • @Israelzebulon put it didn’t work

  • add an input to the side and give an id to it.... within the function you use Document.getElementById(id). value; to add or take the value inside the input

A very simplistic solution would be 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>
