标签:servlet com 方法 package turn 商品 ltm 技术分享 efault 基于Struts2框架下实现Ajax有两种方式,第一种是原声的方式,另外一种是struts2自带的一个插件。 js部分调用方式是一样的: JS代码: 第一种原生的实现方式: Action中创建一个方法: struts.xml中配置: 这种方式不太推荐使用。 这里重点讲解下第二种方式: 1.引入struts2-json-plugin-2.5.2.jar 2.Action中添加类似的如下代码: Struts.xml中配置如下: JS中接受返回结果: 返回JSON格式: JS解析如下: struts中实现ajax的配置信息 标签:servlet com 方法 package turn 商品 ltm 技术分享 efault 原文地址:http://www.cnblogs.com/hmpcly/p/7096469.html 1 function testAjax() {
