测试例子
以下是一个使用的简单例子：
这里我们采用了Uploadify包中自带的php测试脚本作为上传的处理，所以这里安装了wamp作为php的测试环境，在php的网站根目录中，解压上面下载好的Uploadify文件，并创建一个文件上传保存的目录，这里我们在Uploadify的解压目录中创建到了uploads作为文件保存目录。
创建uploadify_test.php文件，添加如下内容：
<html>
<head>
<link href="uploadify-v2.1.4/uploadify.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="uploadify-v2.1.4/jquery-1.4.2.min.js" ></script>

Uploadify插件提示$(“#id”).uploadify is not a function错误可能原因
swfobject.js和jquery.uploadify.v2.1.4.min.js由于使用到了jquery的API，所以这两个文件需要依赖于jquery-1.4.2.min.js这个文件。
正常情况下需要引入如下几个js文件：
<script type="text/javascript" src="uploadify-v2.1.4/jquery-1.4.2.min.js" ></script> <script type="text/javascript" src="uploadify-v2.1.4/swfobject.js" ></script> <script type="text/javascript" src="uploadify-v2.1.4/jquery.uploadify.v2.1.4.min.js" ></script>
而在项目中已经存在了另外一个jquery的JS文件，导致文件冲突。而另外的一个jQuery文件的引入位置位于上面三个js文件引入位置的后面，此时项目中使用的是原本已经存在的jquery的JS文件，导致在加载jquery.uploadify.v2.1.4.min.js文件时还没有可用的jquery相关函数的定义，才会报这个错误。
解决方法：
去掉其中一个jquery的JS文件，并把swfobject.js和jquery.uploadify.v2.1.4.min.js文件放到引入jquery的JS文件的位置的后面即可。
