jquery+css3打造一款ajax分页插件

浏览数：16 / 时间：2015年06月09日

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>
