问题描述
我从本网站尝试和实现实时网络聊天应用程序。我非常新的JavaScript jQuery的,所以我想我刚才复制的榜样,学习,因为我去添加一些东西。
I am following the example from this site to try and implement a live web chat application. I am very new to javascript to jquery, so I thought I'd just copy the example and learn as I go and add things.
这是code,我现在用:
This is the code that I am using:
@{ ViewBag.Title = "OnlineUsers"; } <html> <head> <title>Online Users</title> <link rel="stylesheet" href="cdn.leafletjs/leaflet-0.4/leaflet.css" /> <script src="cdn.leafletjs/leaflet-0.4/leaflet.js"></script> </head> <body> <div id="wrapper"> <div id="upperPanel"> <div> <ul id="messages" itemid="@HttpContext.Current.User.Identity.Name"> </ul> </div> <div id="friends"> </div> </div> <div id="bottomPanel"> <textarea rows="2" cols="100" id="chatMessage"></textarea> <input id="chatSubmitMessage" type="submit" value="Send" style="margin-left: 10px;" /><br /> </div> </div> <script type="text/javascript"> $(function () { var pusher = new window.Pusher('0b7eeff567653e170094'); var channel = pusher.subscribe('chat_channel'); channel.bind('message_received', function (data) { $("#messages"). append('<li>' + data.user + ' ' + data.message + ' ' + data.timestamp + '</li>'); }); $('#chatSubmitMessage').bind('click', function () { $.post("/", { chatMessage: $('#chatMessage').val(), username: $('#messages').attr('itemid') }); }); }); </script> </div> </body> </html>这code给我下面的错误在Chrome调试器:
This code gives me the following error in the Chrome debugger:
Uncaught TypeError: undefined is not a function (anonymous function) fire jquery-1.8.2.js:974 self.add jquery-1.8.2.js:1018 jQuery.fn.jQuery.ready jquery-1.8.2.js:246 jQuery.fn.jQuery.init jquery-1.8.2.js:174 jQuery jquery-1.8.2.js:44 (anonymous function) (anonymous function) jquery-1.8.2.js:564 jQuery.extend.globalEval jquery-1.8.2.js:565 (anonymous function) jquery-1.8.2.js:6006 jQuery.extend.each jquery-1.8.2.js:611 jQuery.fn.extend.domManip jquery-1.8.2.js:5991 jQuery.fn.extend.append jquery-1.8.2.js:5764 jQuery.fn.(anonymous function) jquery-1.8.2.js:6186 $.ajax.success jquery.mobile-1.2.0.js:3685 fire jquery-1.8.2.js:974 self.fireWith jquery-1.8.2.js:1082 done jquery-1.8.2.js:7788 callback我假设的错误是与功能是无名,任何帮助将大大AP preciated。
I'm assuming the error has something to do with the function being unnamed, any help will be greatly appreciated.
推荐答案您不加载的jQuery,但尝试使用它。添加到您的头上
You are not loading jquery, but trying to use it. Add this to your head
<script src="//ajax.googleapis/ajax/libs/jquery/1.8.2/jquery.min.js"></script>更多推荐
