passing a variable to an <input>

[wigglesby]

Hi

 

I have following code:

 

<script type="text/javascript" />
function updateReceivedCartons(){
var cartons = parseFloat(document.getElementById('cartons').value);
var remaining = parseFloat(document.getElementById('txtitemsremaining<? echo $recId ?>').value);
    var received = parseFloat(document.getElementById('txtitemsreceived<? echo $recId ?>').value);
    var gTotal = cartons - received - remaining;
     if (gTotal < 0)
     {
     	alert("The number you entered is too large.");
     }
 else
 {
	 $("#txtitemsreceived<? echo $recId ?>").after("<td class='numbers'><input type='text' disabled='disabled' id='txtitemsreceived<? echo $recId ?>' name='txtitemsreceived<? echo $recId?>' class='teenyinput numbers' value='XXXXXX' /></td>").remove();

 }
}
</script>

 

cartons = 3

received  =1

remaining = 1

 

Now when I set remaining as 1, I then want to pass in the gTotal variables value where XXXXXX is. But I'm not sure how to.

So If the above values are set, XXXXXX should be 1 (3  - 1 - 1 = 1).

Im just not sure how to the the value of the variable and then pass it into value="XXXXXX"

 

Any ideas?
