For better result restrict the text or keypress event

var maxchar = 100;
$('textarea').keypress(function(e){
  if($(this).val().length > maxchar){
      $(this).val($(this).val().substring(0, maxchar));
  }
});

$('#btn').click(function(){

    $('#test').val($('#test').val().slice(0, 100));

You should do something like

$('textarea').keyup(function(){
  if(this.value.length > 100){
    this.value = this.value.substring(0, 100);
  }
})

simply use this 

$('#textarea').bind('keyup', function() {
    $('#textarea').val($('#textarea').val().slice(0, 100));
});
