Input & Textarea Character Limit Display with jQuery


This little jQuery snippet will let you quickly add a limit counter
to input fields to display available remaining characters.
A nice feature to include for improved user experience.

function($) {
$.fn.extend( {
limiter: function(limit, elem) {
$(this).on("keyup focus", function() {
setCount(this, elem);
function setCount(src, elem) {
var chars = src.value.length;
if (chars > limit) {
src.value = src.value.substr(0, limit);
chars = limit;
elem.html( limit – chars );
setCount($(this)[0], elem);

//To setup the limiter, simply include a call similar to the one below:
var elem = $("#chars");
$("#text").limiter(100, elem);

The first parameter is the character limit integer and the second is a jQuery
element representing the target object to display the characters remaining.
This is not a replacement for the maxlength parameter or server-side validation,
just a visual way to represent the limit.
