我已经阅读了一些关于SO的帖子，但在我的情况下，我正在关注所有这些东西，但仍然显示：无不隐藏元素。下面是代码显示：none style not working
jQuery(function($) {
var socket = io.connect();
var $messageForm = $('#message-box');
var $messageBox = $('#message');
var $chat = $('#chat');
var $users = $('#users');
var $nickForm = $('#setNick');
var $nickError = $('#nickError');
var $nickBox = $('#nickname');
$('#message').keydown(function(event) {
if (event.keyCode == 13) {
$(this.form).submit()
return false;
}
});
$nickForm.submit(function(e) {
e.preventDefault();
socket.emit('new user', $nickBox.val(), function(data) {
if (data) {
$('#nickWrap').hide();
console.log("Showing Content Wrap");
$('#contentWrap').show();
} else {
$nickError.html("That nickname is already taken , try something else");
}
});
$nickBox.val('');
});
socket.on('usernames', function(data) {
var html = '<ul>';
for (i = 0; i < data.length; i++) {
html += '<li>' + data[i] + '</li>';
}
html = html + '</ul>';
$users.html(html);
});
$messageForm.submit(function(e) {
e.preventDefault();
socket.emit('send message', $messageBox.val(), function(data) {
$chat.append("<span class='error'>" + data + "</span><br/>");
});
$messageBox.val('');
});
socket.on('new message', function(data) {
$chat.append("<span class='msg'><b>" + data.nick + " :</b>" + data.msg + "</span><br/>");
});
socket.on('whisper', function(data) {
$chat.append("<span class='whisper'><b>" + data.nick + " :</b>" + data.msg + "</span><br/>");
});
socket.on('private', function(data) {
$chat.append("<span class='whisper'><b>" + data.nick + " :</b>" + data.msg + "</span><br/>");

你是什么意思是不是工作？ – brso05
页面加载时隐藏吗？那么当你提交它显示div？ – brso05
这里隐藏得很好 – adeneo
