Regular Expression help

[bamboo]

I'm a newbie to RegExp. I'm having trouble validating a text field to only allow 8 characters, using any combination of 0-9, A-F. I have the following which validates fine for A-F, 8.

var targetChar = /[abcdef]{8}/

However I need to test for 0-9 as well. I know \d matches any digit [0-9] however I can't seem to get this to work when adding this in. Any help would be great. Thanks much.

should just be:

var targetChar = /[abcdef0-9]{8}/

p.s., you could also do:

var targetChar = /[a-f0-9]{8}/;

Thanks CLFlaVA. That seems to work fine. However if I type in aa1122bbz it doesn't validate. However if I do the opposite zbb2211aa it does validate. It's seem that it validates only the first 8 characters. After that it doesn't seem to care. It should throw the alert since there are 9 characters correct?

try

var targetChar = /^[a-f0-9]{8}$/;

Awesome! That was the trick. I was just reading up on negated character class. Thanks again. I appreciate it!

I was just reading up on negated character class.

Just to muddy the waters further, in this case [tt]^[/tt] does not negate the character class: typing a caret after the opening square bracket will negate the character class.

In this case [tt]^[/tt] is an anchor representing the start of the string, and [tt]$[/tt] represents the end.

We love regex
