[Javascript] Regular Exp

[Laurent Muchacho]

hi Hakan,

yes you right it match anything but number. Thanks this do put me in the
right direction but it seems a bit more complicated then I expected because
I'm checking the value on each onKeyUp event. It mean that when you start
typing eg: 1 for 100.55 it return false until you got the whole number.

Thanks for getting back so quick and for the help provided.

Regards

Laurent

This regexp rather matches anything BUT a number, unless I'm completely 
confused.

You could try this, it's untested but should be in the right direction.

var number_re = /[0-9]+\.[0-9]{2}/;
