JQuery keyup/down isn't working in chrome

 $('#user_text').keyup(function(){ var user_text = $('#user_text').val(); $('#user_text_feedback').html(user_text); });

I'm using google chrome as my default browser. I tried to execute the above code but I'm not getting the required output.I also tried using keydown instead of keyup I wasn't getting the proper output

Change $('#user_link') to $('#user_text') :

$('#user_text').keyup(function(){
    var user_text = $('#user_text').val();
    $('#user_text_feedback').html(user_text);
});

Working here you should use #user_text :

 $('#user_text').keyup(function(){ var user_text = $('#user_text').val(); $('#user_text_feedback').html(user_text); });
