JQuery implements the method to limit the number of characters entered in the textarea text box, jquerytextarea
This example describes how jQuery limits the number of characters entered in the textarea text box. Share it with you for your reference. The specific implementation method is as follows:
(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 );}});}) (jQuery); // To setup the limiter, simply include a call similar to the one below: var elem =$ ("# chars"); $ ("# text "). limiter (100, elem );
I hope this article will help you with jQuery programming.
