最近公司的项目将好多分页改成了ajax的前台分页
以前写的分页插件就不好用了,遂重写一个
支持IE6+,但没有动画效果
如果没有硬需求,个人认为没必要多写js让动画在这些浏览器中实现
css3的动画本来就是帮我们取代js中这部分动画代码的
使js更纯粹地去实现逻辑
效果图如下:
调用代码如下:
包括常用的加载失败重试,参数可配置是否能手动输入页码,设置按钮数目,可以调用多个page等等,调用代码很简便
<script type="text/javascript"> var kpage; $(function () { tocount(); }); function tocount() { //初始化 $.ajax({ url: "/Service/DBCount", type: "post", success: function (e) { kpage = $("#divPage").page({ dataCount: e, pageChange: topage }); } }); } function topage(i, s) { //数据查询 $("#divInfo").html("加载中..."); $.ajax({ url: "/Service/List", type: "post", data: { PageSize: s, PageIndex: i }, success: function (r) { $("#tList").html(r); $("#divInfo").html(""); }, error: function () { $("#divInfo").html("加载失败...<a href='javascript:reload();'>重试</href>"); } }); } function reload() { kpage.reload(); } </script>
具体jquery.kun_page.js:

样式和动画都可以自己修改(好吧,动画效果很朴素,闹哪样,明明想了很久好吗)
pageChange事件里面也没有过多的其他处理,比如我们公司前后台处理json就有一套方案,ajax提交的参数也有处理
所以若有需求,完全可以在我的代码上再封装一层
另外插件内公开的方法暂只有几个,可视情况增加
