adding fields + .00

adding ".00"

[bshaffer]

OK! here it goes.

I have 6 fields were user can input a dollar amount, those fields I need to automatically add ".00" if the user does not.I also need those fields to be added up and that value entered into my "total" field including the ".00" if the user hasn't added an amount such as (ex 9.67) into 1 of the 6 fields. The problem that I'm getting is when the user doesn't use an amount like (ex 9.67) the "total" field doesn't give me a ".00".

example
field 1 = 6 need it to be 6.00
field 2 = 5 need it to be 5.00
total = 11 need it to be 11.00

example
field 1 = 6 need it to be 6.00
field 2 = 6.67 this is ok
total = 12.67 this is ok

I hope I made this as clear as possible..Sorry!

Hi,

You can use Number.toFixed() [developer.mozilla.org] to format the result.

total.toFixed(2);

this doesn't seem to work and ideas? it adds the .00 but clears the entire page and puts the number at the top.

function calc(){
one=document.getElementById('box1').value;
two=document.getElementById('box2').value;
three=document.getElementById('box3').value;
four=document.getElementById('box4').value;
five=document.getElementById('box5').value;
six=document.getElementById('box6').value;
total= (one * 1) + (two * 1) + (three * 1) + (four * 1) + (five * 1) + (six * 1);
document.getElementById('total').value= total;
document.write(total.toFixed(2));

Instead of

document.getElementById('total').value= total;
document.write(total.toFixed(2));

try:
document.getElementById('total').value= total.toFixed(2);

Hi,

It's the document.write that's doing that, you'd be better off assigning the result to another text field.

document.getElementById('total').value = total.toFixed(2);

Or a normal element:

document.getElementById('total').innerHTML = total.toFixed(2);
