jquery+css3打造一款ajax分页插件

原文: [原创]jquery+css3打造一款ajax分页插件

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>

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

 

喜欢的可以帮我点一下“推荐”,谢啦!
