Uploadify 之使用

uploadify 3.2.1是 jQuery提供的一个上传插件，其参数详解见 http://www.cnblogs.com/yangy608/p/3915349.html

这里列举一个实际应用的例子：其实是摘自onethink的一段代码，关靠参数，没有实际例子，对于我等初学者实为不利

<script type="text/javascript" src="/uploadify/jquery.min.js"></script>
<script type="text/javascript" src="/uploadify/jquery.uploadify.min.js"></script>
<input type="file" id="upload_picture_{$field.name}">
<input type="hidden" name="{$field.name}" id="cover_id_{$field.name}" value="{$data[$field[‘name‘]]}"/>
<div class="upload-img-box">

<div class="upload-pre-item"><img src="{$data[$field[‘name‘]]|get_cover=‘path‘}"/></div>

</div>
<script type="text/javascript">
                                //上传图片
                                /* 初始化上传插件 */
                                $("#upload_picture_{$field.name}").uploadify({
                                    "height"          : 30,
