textfield/textbox alphanumeric ?
Can i restrict the input in textfield/textbox to alphanumeric only ?
i don't want the user to input !@##$%$#*& <-- these
I just see PHONENUMBER, EMAIL, ... and ANY for all kinds of input.
Not by just using the libraries.
You could however, keep reading what they have typed so far, removed any non alphanumeric chars and then
re-insert whats left back into the textbox.
Its not a very good solution though, and it would be annoying to use if you were trying to insert a name
as say, my name, alex_crowther
