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enctype='multipart/form-data' target='hidden_frame'

然后，处理页处理后返回out.println('<script>parent.callback(“ 返回值 ”)</script>');

列表页执行回调函数！

selectaddress.jsp
