不 运行之后 有的浏览器不 支持 --------------------编程问答-------------------- 怎么个不支持，哪些浏览器不支持？用struts的插件可以否？ --------------------编程问答-------------------- 我感觉，浏览器不支持的不是你的上传，而是你的自定义标签 --------------------编程问答-------------------- ie8 ie7 不支持 你有没有不用框架的上传下载代码呀 参考一下 --------------------编程问答-------------------- 对 就是primefaces 的组件才发生这状况 你有没有不用框架支持各ie的上传下载呀 --------------------编程问答--------------------
补充：Java , Web 开发
