Form submit on max characters???

[FlikstRR]

Not sure if this is something directly ajax or just javascript in general but im very new to ajax and would really appreciate some pointers/solution to this one if at all possible. Being that i wish to submit a form without page load im going to guess at ajax  :P

i have a barcode scanner'esk' input that submits to a text input. the code is always 12 characters long. They also have the option to type the code (again 12 characters). Once the code reaches 12 characters i want the form to submit so it can be saved to the sql given an id etc etc (i can do all that) and then be ready for the next one..

the aim being so a user has no keyboard entry.. just scans product... it submits so they wait a second or two... scan next one and so on.

can this be done?

I think it may have something to do with 'taskInput.onkeyup'

thank you. Phil

Submitting alone can be done strictly with JS.  No AJAX needed.  Keep in mind however, that if they are keying this in, you probably don't want to auto-submit in case they screw up the code.

And if you're not using a keyboard, there isn't really a way to do this unless you're using an ActiveX control because there is no way to take input from the PC and stuff it into a website.  And even then, if you're not using a keyboard, there is no way to trigger an event to check the length of the string.

EDIT:... I guess you could use onChange... but I'm not sure that would work correctly or not.
