创建HTML页面

项目中实现的原代码,无删减直接贴上。具体请参考“添加附件”按钮相关操作。
注意引入:cardRansomManage.js,ajaxfileupload.js.




<#include "../ftl/includes/easyui.ftl"/>

账户管理-预付卡赎回管理


 
当前位置:预付费卡综合管理系统 > 预付卡赎回管理 >  赎回申请 > 
赎回申请
增加附件 上传附件并保存 <@verifyRes res="/ransom/ransomInvalid?Apply"> 申    请 <@verifyRes res="/ransom/ransomInvalid?Audit"> 审    核 驳    回
赎回单号:
申请人:
表单状态:
<#if order.attachment??> <#list order.attachment as attach>
附件(已上传):
   删除 下载
正在处理,请稍后...

创建Javascript库

cardRansomManage.js

//设置面罩的z-index,打开进度条
