Subject: OT: javascript add problem
Sorry about the OT question, but am stumped as to why this won't work.
Trying
to use JavaScript to add the numbers in form fields together, instead of
adding them, it is appending them to each other. Here is my code:
<script language="JavaScript">
function AddToBasket()
{
OrderBooks.TotalQty.value = 0
OrderBooks.TotalQty.value = eval(OrderBooks.SW.value +
OrderBooks.SP.value)
}
</script>
It is taking the value of OrderBooks.SP.value and apending it to
OrderBooks.SW.value instead of adding them. For example,
OrderBooks.SW.value
= 3 and OrderBooks.SP.value = 5, I am getting 35 instead of 8. Have tried
it
without the eval() in there and have set each form value equal to a
javascript
variable also with no change in results.
