您好,我在过去3个小时内遇到过此代码的问题,我希望有人可以帮助我.
jQuery的
$(document).ready(function() {
$("img").draggable();});
HTML标题
<head>
<title>Chess</title>
<Meta http-equiv="Content-type" content="text/html;charset=UTF-8">
<link rel="stylesheet" type="text/css" href="reset.css" />
<link rel="stylesheet" type="text/css" href="default.css"/>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.9.1/jquery-ui.min.js"></script>
<script type="text/javascript" src="default.js"></script>
</head>
FireBug错误
TypeError: $("img").draggable is not a function [Break On This Error] $("img").draggable();
我的代码在codecademy.com上完美运行但是当我在localhost或我的服务器上尝试时,我不断收到此错误消息.我在这做错了什么？

解决方法
你没有加载jquery,只有jquery-ui. jquery本身不是由jquery-ui加载的,所以你需要2个不同的脚本标签.
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.9.1/jquery-ui.min.js"></script>
