instant addition puzzle

[loquela]

Hi there,

I am looking for a script that will instantly add up the totals from 5 input fields and display the sum of each field on screen as the user types in the values.

 

Any ideas?

 

Thanks in advance!

Create a function that adds up the numbers. Then bind each input field to the function using onkeyup.

 

Here's an example:

Number 1: <input type="text" id="it1" onkeyup='add();' /><br />
Number 2: <input type="text" id="it2" onkeyup='add();' /><br />
Answer: <span id='answer'></span>

<script type='text/javascript'>
function add(){document.getElementById('answer').innerHTML = ((int) document.getElementById('it1').value) + ((int) document.getElementById('it2').value);}
</script>
