列表页：selectaddress.jsp
js页：ajax_edit.js
jsp处理页：editaddress.jsp
上传工具类：UploadUtil.java
思想：由于安全问题，javascript操纵不了文件， 导致ajax不能动态上传文件，所以选择了iframe，
列表页把form表单提交到一个隐式的iframe里面，设置表单的属性
复制代码 代码如下:
enctype='multipart/form-data' target='hidden_frame'
然后，处理页处理后返回
复制代码 代码如下:
out.println('<script>parent.callback(" 返回值 ")</script>');
列表页执行回调函数！
