User:Majr/inputCounter.js/doc

Adds a character counter to input fields with a max length, showing how many more characters you can type. It allows you to type more characters than the limit and will display how many characters you've gone over. The script also adds the length of the selected predefined reason on the delete and protect pages to the amount of characters used, giving a true representation of how many characters are left.

Usage
 // User:Majr/inputCounter.js importScript( 'User:Majr/inputCounter.js' );
