Stop Verbosity is a jQuery plugin that limits the amount of text that is permitted in a textarea element by replicating the maxlength attribute for the textarea.
A line of text, the indicator/counter, counts characters used or remaining when text is entered into the textarea. Once the limit is reached, there is no more text input from typing, pasting or drag and drop.
Bootstrap MaxLength plugin integrates by default with Twitter Bootstrap using badges to display the maximum lenght of the field where the user is inserting text. This plugin uses the HTML5 attribute "maxlength" to work.
The indicator badge show up on focusing on the element, and disappear when the focus is lost.
MaxLength Plugin simply reports back the number of characters left the user has, with a few extra bells and whistles.
