xpsharp通过本文主要向大家介绍了jsp+ajax实现无刷新上传文件的方法等相关知识,希望对您有所帮助,也希望大家支持linkedu.com www.linkedu.com
本文实例讲述了jsp+ajax实现无刷新上传文件的方法。分享给大家供大家参考，具体如下：
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 然后，处理页处理后返回
列表页执行回调函数！
selectaddress.jsp
