这次给大家带来怎么实现不刷新的Ajax分页,实现不刷新Ajax分页的注意事项有哪些,下面就是实战案例,一起来看一下。

紧接着上篇—分页技术原理与实现之Java+Oracle代码实现分页(二) ,本篇继续分析分页技术。上篇讲的是分页技术的代码实现,这篇继续分析一下分页技术的效果控制。
上篇已经用代码简单的实现了一个分页。但是我们都看到,代码中每次通过servlet请求取得结果集后,都会转向到一个jsp页面显示结果,这样每次查询页面都会刷新一下,比如查询出现结果集后要查看第三页,页面就会刷新一下。这样页面给人的效果感觉就会有点不舒服,所以我们希望能够在通过条件查询结果集后无论访问哪一页,页面都不会刷新,而只是结果集变化。要解决这个,我想大家很容易就会想到Ajax了。
是啊,这就要请Ajax出山了。当通过查询条件查询到结果集后,以后每次访问任何一页都通过Ajax来访问,使用异步Ajax与Servlet进行交互,将结果查询出来返回给Ajax,这样页面内容因为Ajax返回结果而改变,而页面却不会刷新,这就实现了无刷新的分页技术。
下面我们来看一个简单的无刷新分页实现,代码如下:
