Any way to update a character count from a text box?

[Mike Grigsby]

I need to track how many characters are being entered in a text field (happens to be HTML control) for billing purposes. Is there any way to make the field check the contents as they are being typed? This might also be used when checking for illegal characters in a field. It would be like a send to server type embed, but I don't see one. Anyone have any experience? Thank you!

Hi Mike,

it can be done using JavaScript - but it's not exactly trivial.

You can of course set the maximum length of the text field itself.
(The Max Length setting.)
