Uploadify是一款功能强大，高度可定制的文件上传插件，实现的效果非常不错，带进度显示。在最简单的方式下，Uploadify使用很少的代码就可以运行起来。
Uploadify官方下载地址：http://www.uploadify.com/download/

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> 
  <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> 

  <style type="text/css">
    #custom-demo .uploadifyQueueItem {
     background-color: #FFFFFF;
     border: none;
     border-bottom: 1px solid #E5E5E5;
     font: 11px Verdana, Geneva, sans-serif;
     height: 50px;
     margin-top: 0;
     padding: 10px;
     width: 350px;
    }
    #custom-demo .uploadifyError {
     background-color: #FDE5DD !important;
     border: none !important;
     border-bottom: 1px solid #FBCBBC !important;
    }
    #custom-demo .uploadifyQueueItem .cancel {
     float: right;
    }
    #custom-demo .uploadifyQueue .completed {
     color: #C5C5C5;
    }
    #custom-demo .uploadifyProgress {
     background-color: #E5E5E5;
     margin-top: 10px;
     width: 100%;
    }
    #custom-demo .uploadifyProgressBar {
     background-color: #0099FF;
     height: 3px;
     width: 1px;
    }
    #custom-demo #custom-queue {
     border: 1px solid #E5E5E5;
     height: 213px;
     margin-bottom: 10px;
     width: 370px;
    }        
  </style>  

  <script type="text/javascript">
    $(function() {
    $('#custom_file_upload').uploadify({
       'uploader'    : 'uploadify-v2.1.4/uploadify.swf',
       'script'     : 'uploadify-v2.1.4/uploadify.php',
       'cancelImg'   : 'uploadify-v2.1.4/cancel.png',
       'folder'     : 'uploadify-v2.1.4/uploads',
       'multi'     : true,
       'auto'      : true,
       'fileExt'    : '*.jpg;*.gif;*.png;*.txt',
       'fileDesc'    : 'Image Files (.JPG, .GIF, .PNG)',
       'queueID'    : 'custom-queue',
       'queueSizeLimit' : 3,
       'simUploadLimit' : 3,
       'sizeLimit'  : 1024000,
       'removeCompleted': false,
       'onSelectOnce'  : function(event,data) {
         $('#status-message').text(data.filesSelected + ' files have been added to the queue.');
        },
       'onAllComplete' : function(event,data) {
         $('#status-message').text(data.filesUploaded + ' files uploaded, ' + data.errors + ' errors.');
        }
      });        
    });
  </script>
</head>
<body>
  <div id="custom-demo" class="demo">

     <h2 id="Custom-Demo">Custom Demo</h2>
    <p>Uploadify is fully customizable. Here is an implementation with multiple files, auto uploads, limited file types, limited queue size, and custom onSelectOnce and onAllComplete functions.</p>
    <div class="demo-box">
      <div id="status-message">Select some files to upload:</div>

      <div id="custom-queue"></div>
      <input id="custom_file_upload" type="file" name="Filedata" />    
    </div>
  </div>
</body>
</html>

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。

JavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AM

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AM

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AM

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AM

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

From C/C to JavaScript: How It All WorksApr 14, 2025 am 12:05 AM

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

JavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AM

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

Beyond the Browser: JavaScript in the Real WorldApr 12, 2025 am 12:06 AM

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.
