Javascript newbie: Firefox OnChange Problem

[supergrover1981]

Gidday Gang,

I'm currently trying to make a simple price calculator for a web page. It works like this:

- A visitor enters a quantity of each product they desire in a text input box

- A read-only input box then displays the subtotal for that item(trigged by ONCHANGE of the quantity text box)

- A read-only input box displays the total for all items (triggered by the ONCHANGE of the quantity text box)


The calculator works fine in Internet Explorer, but the subtotal/total boxes don't display anything at all in Firefox. Page can be seen at

If anyone has any suggestions at all for this problem, I'd be most appreciative.

Cheers gang,
- JB

It's working fine for me in Firefox 1.5.0.7 as soon as I click somewhere besides the textbox I just changed the quantity in. You might try using onblur so you get consistent results between browsers, and the amounts only update after someone is finished typing a quantity in the text input.

You also need to do some error checking to make sure the user has entered only an integer. I used a letter just to test, and your form had $NaN for the individual item total as well as the final total.
