Question

I have a form like this:

<form name="calc" action="" id="calc">
<?php for($i=0; $i<15; $i++) { ?>
<input type="text" name="txt1[$i]" onkeyup="calcNumber()"/>
<input type="text" name="txt2[$i]" onkeyup="calcNumber()"/>
<input type="text" name="txt3[$i]" onkeyup="calcNumber()"/>
<span id="tot[$i]"></span>
<?php } ?>
</form>

And this is javascript code:

<script type="text/javascript">
function calcNumber() {

for(var j=0; j<15; j++) {

var totNumber[j] = document.calc.txt1[j].value + document.calc.txt2[j].value + document.calc.txt3[j].value;

document.getElementById('tot[j]').innerHTML = totNumber[j];
}

}
</script>

No error.. But no result either. Please let me know what I have done wrong. Thanks.

Answer 1

I have figured out the problem, just insert array after tot in function calcNumber(), but not within tot.

Thank you guys so much for your help.
