Interactive Website: Status Update. disable the button


This is my code:

var main = function() {
('.btn').click(function() { var post = (’.statusbox’).val();
('<li>').text(post).prependTo('.posts'); (’.status-box’).val(’’);

('.status-box').keyup(function() { var postLength = (this).val().length();
var charactersleft = 140 - postLength;

if (charactersleft < 0) {

else if(charactersleft === 140) {

else {



This is the error that i get when i try to submit it:
Oops, try again.
Remember to add the line $(’.btn’).addClass(‘disabled’); outside your keyup event handler

Can someone help me with this problem?


The problem should be corrected when you close your main function at the end and not at the beginning of the script. Close it just before the line $(document).ready(main);


one thing I observed instead of btn, .btn should be use
