HTML分页插件功能实现

分页功能实现案例展示如下：在这里插入图片描述

1.先引入css样式和jQuery，再引入分页插件toPage.js，谨记顺序不能乱

<link rel="stylesheet" href="css/toPage.css">
<script src="script/jquery.min.js"></script>
<link rel="stylesheet" href="css/toPage.css">

2.定义两个分页容器的div展示，实际应用时定义一个分页容器即可，这里主要是展示案例所以定义了两个容器，如下：

<!--分页容器_1-->
<div class="page_1"></div>
<!--分页容器_2-->
<div class="page_2"></div>

3.接着我们使用插件写js代码

 <!--插件使用--><script>/*容器1参数*/var obj_1={obj_box:'.page_1',//翻页容器total_item:72//条目总数/*per_num:10,//每页条目数current_page:8//当前页*/};/*容器2参数*/var obj_2={obj_box:'.page_2',//翻页容器total_item:372,//条目总数per_num:20,//每页条目数current_page:8//当前页};/*调用分页方法,初始化数据*/page_ctrl(obj_1);page_ctrl(obj_2);</script>

4.关于如何修改每页展示的内容：在toPage.js里面有一个change_content()方法，请自行修改即可
以下代码解读：定义了ul，li，分页展示：编号，分页条目；最后要记得吧内容绑定到$(obj_box).children(’.page_content’).html下才能展示出来

   function change_content() {/*此处根据项目实际自行编写页面显示内容的方法,举例说明:*/var page_content='<ul style="width: 300px;margin: 10px auto;">';//当前页内容for(var i=0;i<per_num;i++){page_content+='<li>'+((current_page-1)*per_num+i+1)+',分页条目</li>';}page_content+='</ul>';$(obj_box).children('.page_content').html(page_content);}

另外，也可以也可以写ajax来展示分页数据，如下：


function change_content() {$.ajax({type: 'get',url: 'http://xxxx',dataType: "json",data: json_data,error: function (data) {//请求失败时被调用的函数 err_func(data);},success: function (data) {//对数据的各种操作operation(data),返回需要展示的页面内容，//最后绑定到$(obj_box).children('.page_content').html即可展示出来var page_content=operation(data);$(obj_box).children('.page_content').html(page_content);}});
}

我自己制作的小说网站，也使用了该分页功能，感觉不错，值得推荐
