I'm sorry, I was confused. I thought this was a PHP error - can you paste line 31 here and provide a link to your page?

In the code:Originally Posted by Nile
how can i used it in php and also the onkeyenter because in my real webpage my code for input type is like this:Code:<html> <head> <script type="text/javascript"> var subtract = function(c, b, output){ output.value = c.value-b.value; } </script> <input type="text" id="c" value="0"/>-<input type="text" id="b" value="0"/>=<input type="text" id="a" value="0"/><br/> <input type="text" id="d" value="0" /> <script type="text/javascript"> document.getElementById('c').onmousedown = function(){ subtract(document.getElementById('c'), document.getElementById('b'), document.getElementById('a'), document.getElementById('d')); } document.getElementById('b').onmousedown = function(){ subtract(document.getElementById('c'), document.getElementById('b'), document.getElementById('a'), document.getElementById('d')); } </script> </head> </html>
PHP Code:echo "\n\t\t<td><input size='6' type='text' name='inqty[]' id='inqty" . $ctr . "' onkeypress='return handleEnter(event,\"outqty" . $ctr . "\");' /></td>";
echo "\n\t\t<td><input size='6' type='text' name='outqty[]' id='outqty" . $ctr . "' onkeypress='return handleEnter(event,\"idno" . $ctr . "\");' /></td>";
echo "\n\t\t<td><input size='6' type='text' name='varqty[]' id='varqty" . $ctr . "' onkeypress='return handleEnter(event,\"varsublot" . $ctr . "\");' /></td>";
and i have this code:
</style>
<script language="javascript">
function handleEnter(e, nextfield)
{
var characterCode = (e && e.which)? e.which: e.keyCode;
if(characterCode == 13)
{
document.getElementById(nextfield).focus();
return false;
}
else
{
return true;
}
}
</script>

Give the ids of c, b, and a to the right ones (c = first number, b = second, a = result, because c-b=a, and a+b=c)

You mean it should be like this
It is onmousedown , I want it press enter.Code:echo "\n\t\t<td><input size='6' type='text' name='inqty[]' id='a" . $ctr . "' onkeypress='return handleEnter(event,\"b" . $ctr . "\");' /></td>"; echo "\n\t\t<td><input size='6' type='text' name='outqty[]' id='b" . $ctr . "' onkeypress='return handleEnter(event,\"idno" . $ctr . "\");' /></td>"; echo "\n\t\t<td><input size='6' type='text' name='varqty[]' id='c" . $ctr . "' onkeypress='return handleEnter(event,\"varsublot" . $ctr . "\");' /></td>"; how about this code: <script type="text/javascript"> document.getElementById('c').onmousedown = function(){ subtract(document.getElementById('c'), document.getElementById('b'), document.getElementById('a'), document.getElementById('d')); } document.getElementById('b').onmousedown = function(){ subtract(document.getElementById('c'), document.getElementById('b'), document.getElementById('a'), document.getElementById('d')); } </script>

Honestly, I don't know where i can put the code you suggeted. I really need to fix this problem, i don't know why, I'm sorry I'm not good in coding and analyzing.
I only want is the input and output should be subtract and the result would appear in varqty text field. when they press enter key.
Thank you

It should be like this:
Tell me if that works, then I'll do the enter.Code:echo "\n\t\t<td><input size='6' type='text' name='inqty[]' id='c" . $ctr . "' onkeypress='return handleEnter(event,\"b" . $ctr . "\");' /></td>"; echo "\n\t\t<td><input size='6' type='text' name='outqty[]' id='b" . $ctr . "' onkeypress='return handleEnter(event,\"idno" . $ctr . "\");' /></td>"; echo "\n\t\t<td><input size='6' type='text' name='varqty[]' id='a" . $ctr . "' onkeypress='return handleEnter(event,\"varsublot" . $ctr . "\");' /></td>"; how about this code: <script type="text/javascript"> document.getElementById('c').onmousedown = function(){ subtract(document.getElementById('c'), document.getElementById('b'), document.getElementById('a'), document.getElementById('d')); } document.getElementById('b').onmousedown = function(){ subtract(document.getElementById('c'), document.getElementById('b'), document.getElementById('a'), document.getElementById('d')); } </script>

I tried it and I got this error:
Line: 30
Error: 'document.getElementById(...)' is null or not an object

This should do it:
Code:<input type="text" id="c" value="0"/>-<input type="text" id="b" value="5"/>=<input disabled type="text" id="a" value="0" style="color:#000" /> <script type="text/javascript"> var c = document.getElementById('c'); var b = document.getElementById('b'); var a = document.getElementById('a'); //define c, b, a var performSubtract = function(e) { var key = e ? e.which : window.event.keyCode; //get the key, 13 = ENTER if(key == 13){ a.value = c.value - b.value; //subtract and set } }; c.onkeydown = b.onkeydown = performSubtract; </script>
