Anyone know Javascript?

[nugenhost]

I'm in need of a bit of help on a javascript form. I know a bit but I'm having an issue with getting what I need done, done correctly.

 

A bit of info. What I have is a financial form. I have 2 columns that need to be each added up then the total of those two columns need to be totaled together later in the form. I can get the one side to calculate out and total but I can't get the second side to calculate out correctly.

 

The other issue I'm having with it is unless I put a .15 (cents) value after a dollar amount it's not giving me .00 after the dollar amount. I'm at a loss on how to fix that as well.

 

function b_startCalc(){
 interval = setInterval("calc()",1);
}
function calc(){
 v1 = document.autoForm.b_firstjob.value;
 v2 = document.autoForm.b_oth_income.value;
 document.autoForm.b_total_income.value = (v1 * 1) + (v2 * 1);
}
function b_stopCalc(){
 clearInterval(interval);
}

 

As you can see it's just a basic add script, but I'm at a loss. If anyone can help me I'd very much appreciate it.

 

Thanks.

I don't know what you mean by not getting "one side to calculate out", but for the number formatting you can use the number.toFixed(x) javascript function (it will round naturally).

 

replace:

document.autoForm.b_total_income.value = (v1 * 1) + (v2 * 1);

 

with:

var total;

total = v1+ v2;

document.autoForm.b_total_income.value = total.toFixed(2);

 

edit...

If you have losts of visitors with older browsers or js, you should first test if the function exists with "if (total.toFixed)"
