Character Counter/Limiter using Jquery
In today’s tutorial we are going to create a character counter that will display a feedback to the user on the number of remaining characters that they are allowed to enter.
In the next post we will turn this jQuery code into a plugin which is pretty much easy and will come with a bunch of customizable options
This will definitely improve user experience and interaction with your website and web applications by displaying feedback as the user types characters into input fields.
Listen for changes and keypress events on the textarea, get the length of the text that has been entered this as you guessed it will be used to calculate the remaining characters to be entered by the user by subtracting it from the limit variable.
A couple of if statements will test the number of characters remaining on each change and keypress event on the textarea and add and remove classes on the span display that will improve the user experience.
