javascript如何在chrome和IE上按预期工作，但不是FF

Question

For some reason my 2 amount recieved inputs show up blank in Firefox, but work correctly in Chrome and Internet Explorer.

Can anyone explain why this is?

also bonus points to anyone who can tell me why the hardcover calculator will allow me to put more than 1200 pages when it should be throwing an error

Answer 1

Check your FF javascript console (shift-ctrl-J):

scd1 is not defined   http://vbwpublishing.com/calcpage.php    Line: 403

which is

if ($(scd1).hasClass('s')){sd = .25}

You're not executing that in a .ready() block, and the <li> with that ID is farther down the page, so it's not defined yet that point, killing the rest of the script execution.
