I want to prevent the user from entering more than 100 characters into a textarea. I already wrote the code that will detect when the user's post reaches 100 characters. But I have no idea how to prevent him from typing any more beyond that point:

```
$(document).ready(function(){

   $('.comment').keyup(function(){
       var count = this.value.length;
       if (count > 100) {

           // what goes here???

       }           
   });

});

  <textarea class="comment" rows="10" cols="30"></textarea>

```
