如何将输入框的值添加到数组中，然后显示该数组的内容？这是我想出的，我不确定为什么它不起作用-console.log也没有向控制台发布任何内容。

var user = user;
if (!user) {
  user = prompt('Please choose a username:');
  if (!user) {
    alert('Your name has been set to "Anonymous"');
  } else {
      alert('Your name has been set to "'+ user +'"');
  }
}

var items = [];
function userArray() {
    items.push(user);
    return false;
    console.log(items);
    }

socket.on('onlineUsers', function (data) {
      $('.dispUser').html(items);
    });

该文件中的其余代码在下面，以防万一。...（根据第一个答案更改了return语句）

var user = user;
if (!user) {
  user = prompt('Please choose a username:');
  if (!user) {
    alert('Your name has been set to "Anonymous"');
  } else {
      alert('Your name has been set to "'+ user +'"');
  } 
}

var items = [];

function userArray() {
    items.push(users);
    console.log(items);
    return false;
    }

socket.on('onlineUsers', function (data) {
      $('.dispUser').html(items);
    });

//Counts the number of users online
socket.on('count', function (data) {
  $('.user-count').html(data);
});

//Receives messages and outputs it to the chat section
socket.on('message', function (data) {
  $('.chat').append('<p><strong>' + data.user + '</strong>: ' + data.message + '</p>');
  $('.chat').scrollTop($('.chat').height());
});


//SENDING OF THE MESSAGE
//Submit the form through HTTPS
$('form').submit(function (e) {
  e.preventDefault();

  // Retrieve the message from the user
  var message = $(e.target).find('input').val();

  // Send the message to the server
  socket.emit('message', {
    user: user || 'Anonymous',
    message: message
  });

  // Clears the message box after the message has been sent
  e.target.reset();
  $(e.target).find('input').focus();
});
