This script will format an input of type="text" or type="tel" into XXX-XXX-XXXX.
It listens on events click and keyup allowing only digits, arrow keys and delete and backspace.
This script works on all modern browsers including IE9 and above.
Add the script to your page. Set the classname for all inputs elements that you wish to have formatted by the script. Pass the classname you set, as string to the setup function named setupTIFs("classname_string").
The Tel_inp_formatter class uses the .addEventListener() method which is not supported by IE8 and below. There are two event handlers, one for clicks and the other for keyups.
The minified script was minified using the closure compiler with the "Optimization:" level radio button selected to (O)Advanced rather than default ( )Simple and all unchecked defaults for formatting.
