Character count in text field Javascript

[lomokev]

can anybody point me in the right direction of a script that will check the amount of characters in a form field field as the user types in it and as soon as there reach a certon amount an alert will pop telling them they have typed to much?

Kinda off topic but I know you can also do this in PHP.

to do it in php the form would have to be submitted first javascript can do a check on the client side first. By all means tho it is best practice to check server side as well to ensure the client hasnt bypassed checks ie by turning javascript off.
