jquery+css3打造一款ajax分页插件

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

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！
