Max characters in textarea with jquery

Question

I have the following code, and I\'m kind of stuck on what to do next. The idea is when you enter text into a text area a counter tells you how many characters you have left.

Answer 1

try this.

var charLmt = "200";//max charterer 
 $("#send-txt").keydown(function(){
   var _msgLenght = $(this).val().length;
   if (_msgLenght > charLmt) {
   $(this).val($(this).val().substring(0, charLmt));
  }
});
