[Javascript] Q on interuppting char entry

[BEKIM BACAJ]

I admire your script, but it's to messy for me.
I vould rather simply set the maxLength var for the text input and then 
retrieve the length from last onkeyup event to se if the maxLength is met, 
and then set the onkeypress to false, -no other character will ocur and you 
will get rid of that 'flash' forever.

So, try to return the keypress to false after the char limit is met.

Cheers!
