OT javascript addition

Thanks Brian!
Tim,
Below is a cut and paste of some javascript that I use to process numeric
fields and push calculated results into other fields on the page. It's
pretty well documented so that you can see what and how it does it... You
can easily modify it to do whatever math you might need. Notice how it loops
over the fields in the form... collecting the values and finally calculating
new results with the values it collected... it even changes the colors on
some of the result fields if so desired.
Hope this helps.

Wow, that's correct but it sure does have a lot of parentheses.
Shouldn't the order of precedence be enough to get the addition correct?
sorry
try this:
if ((eval(document.newBillingInfo.SCEPbilledAmount.value)) +
(eval(document.newBillingInfo.SCEPpenaltyAmount.value)) +
(eval(document.newBillingInfo.SCEPdelinquentAmount.value))) !=
document.newBillingInfo.SCEPtotalAmount.value)
SK
Thanks Stephen.. I tried that earlier but that only concatenates it
Tim,
try adding () around the addition part like so:
if ((document.newBillingInfo.SCEPbilledAmount.value +
document.newBillingInfo.SCEPpenaltyAmount.value +
document.newBillingInfo.SCEPdelinquentAmount.value) !=
document.newBillingInfo.SCEPtotalAmount.value)
This should force the addition to take place before the comparison.
PS are you checking for numeric input only
This could be done like so:
if ((isNaN(document.newBillingInfo.SCEPbilledAmount.value)) ||
(isNaN(document.newBillingInfo.SCEPpenaltyAmount.value)) ||
(isNaN(document.newBillingInfo.SCEPdelinquentAmount.value)) ||
(isNaN(document.newBillingInfo.SCEPtotalAmount.value))
{
alert("The amounts must be numeric, Please
check the values.")
document.newBillingInfo.SCEPbilledAmount.focus()
return false;
}
else
{
if ((document.newBillingInfo.SCEPbilledAmount.value +
document.newBillingInfo.SCEPpenaltyAmount.value +
document.newBillingInfo.SCEPdelinquentAmount.value) !=
document.newBillingInfo.SCEPtotalAmount.value)
{
alert("The total Billing amount does not add up correctly,
Please check the values.")
document.newBillingInfo.SCEPbilledAmount.focus()
return false;
}
return true;
}
}
or something like that ;-)
this is untested code but hopefully will give you something to work
with.

Hello,
Can anybody show me how you would I would validate the sum of several
text boxes? This is what I'm trying to use but not having luck.. thanks

Hi Brook,
this is what I'm using but getting "expecting )" error... please help =)
function validate()
{
var sumValue =
eval(document.newBillingInfo.SCEPbilledAmount.value.valueOf()) +
eval(document newBillingInfo.SCEPpenaltyAmount.value.valueOf()) +
eval(document newBillingInfo.SCEPdelinquentAmount.value.valueOf())
var total = eval("document.newBillingInfo.SCEPtotalAmount.value")
if (sumValue != total)
{
alert(sumValue)
document.newBillingInfo.SCEPbilledAmount.focus()
return false;
}
return true;
}
I had the same problem the other day. This works FOR SURE:
eval(document.newBillingInfo.SCEPbilledAmount.value.valueOf())+eval(document
newBillingInfo.SCEPpenaltyAmount.value.valueOf())
Using the valueOf() function converts a string to a number.

Another workaround is using the old "subtract zero" trick:
if ((document.newBillingInfo.SCEPbilledAmount.value-0) +
(document.newBillingInfo.SCEPpenaltyAmount.value-0) +
(document.newBillingInfo.SCEPdelinquentAmount.value-0) !=
(document.newBillingInfo.SCEPtotalAmount.value-0))
This forces JavaScript to recast the values as numbers.

but keep in mind that eval() is a little slower in processing time bacause
you are first converting a string value, then interpreting it.
While I know it's needed quite often, I would try to avoid the use of eval()
whenever possible - especially if you are dealing with numeric values.
Also, in this case if your numbers are formatted, then eval() will end up
raising an error.
My thoughts.

Try doing eval(document.newBillingInfo.SCEPbilledAmount.value) +
eval(document.newBillIngo.SCEPpenaltyAmount.value), etc. At least in
ActionScript (Flash) this forces the value to be treated as a number for
addition purposes. A quick test in IE javascript showed it to work there
also.

If that's the case, add a parseInt() or parseFloat() around each variable to
make sure it is in fact a numeric value. Or you may have to do some
validation first (i.e. can the user enter "HELLO" for a numeric value?).
Also on this note, you might have to strip any formatting (i.e. "$1,000.00"
and "1,000.00" will not be interpreted as a number by javascript - the comma
and dollar sign need to be stripped).

You'll have to use parseFloat or parseInt to explicitly cast the value
to a number. Then you'll be able to add them.
However, a BIG word of warning: JavaScript SUCKS at proper floating
point manipulation.
There are functions that you can find that'll clear up the numbers
before you add them that can help, or if you're in using IE only, use
VBScript instead.

if ((document.newBillingInfo.SCEPbilledAmount.value +
document.newBillingInfo.SCEPpenaltyAmount.value +
document.newBillingInfo.SCEPdelinquentAmount.value) !=
document.newBillingInfo.SCEPtotalAmount.value)
This should force the addition to take place before the comparison.
PS are you checking for numeric input only
This could be done like so:
if ((isNaN(document.newBillingInfo.SCEPbilledAmount.value)) ||
(isNaN(document.newBillingInfo.SCEPpenaltyAmount.value)) ||
(isNaN(document.newBillingInfo.SCEPdelinquentAmount.value)) ||
(isNaN(document.newBillingInfo.SCEPtotalAmount.value))
{
alert("The amounts must be numeric, Please
check the values.")
document.newBillingInfo.SCEPbilledAmount.focus()
return false;
}
else
{
if ((document.newBillingInfo.SCEPbilledAmount.value +
document.newBillingInfo.SCEPpenaltyAmount.value +
document.newBillingInfo.SCEPdelinquentAmount.value) !=
document.newBillingInfo.SCEPtotalAmount.value)
{
alert("The total Billing amount does not add up correctly, Please
check the values.")
document.newBillingInfo.SCEPbilledAmount.focus()
return false;
}
return true;
}
}
or something like that ;-)
this is untested code but hopefully will give you something to work with.

document.newBillingInfo.SCEPpenaltyAmount.value +
document.newBillingInfo.SCEPdelinquentAmount.value !=
document.newBillingInfo.SCEPtotalAmount.value)
{
