This article will introduce to you bootstrap the two front-end and back-end implementation methods of table paging. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to everyone.

Two ways of paginating bootstrap table:
Front-end paging: Query all data from the database at one time and perform paging on the front-end (front-end paging can be used when the amount of data is small or the logic processing is not complex)
Server Paging: Only query the pieces of data required for loading the current page each time

Paging effect (please ignore the style)
1: Prepare js, css and other files
▶ Place the downloaded documents directly into the webapp directory
▶The page introduces the required js and css
<!-- 引入的css文件 --> <link href="bootstrap/css/bootstrap.min.css" rel="stylesheet" /> <link href="bootstrap-table/dist/bootstrap-table.min.css" rel="stylesheet"> <!-- 引入的js文件 --> <script src="jquery/jquery.min.js"></script> <script src="bootstrap/js/bootstrap.min.js"></script> <script src="bootstrap-table/dist/bootstrap-table.min.js"></script> <script src="bootstrap-table/dist/locale/bootstrap-table-zh-CN.min.js"></script>
2: HTML page tag content
<div class="panel panel-default"> <div class="panel-heading"> 查询条件 </div> <div class="panel-body form-group" style="margin-bottom:0px;"> <label class="col-sm-1 control-label" style="text-align: right; margin-top:5px">姓名:</label> <div class="col-sm-2"> <input type="text" class="form-control" name="Name" id="search_name"/> </div> <label class="col-sm-1 control-label" style="text-align: right; margin-top:5px">手机号:</label> <div class="col-sm-2"> <input type="text" class="form-control" name="Name" id="search_tel"/> </div> <div class="col-sm-1 col-sm-offset-4"> <button class="btn btn-primary" id="search_btn">查询</button> </div> </div> </div> <table id="mytab" class="table table-hover"></table>
3: JS paging Code
$('#mytab').bootstrapTable({ method : 'get', url : "user/getUserListPage",//请求路径 striped : true, //是否显示行间隔色 pageNumber : 1, //初始化加载第一页 pagination : true,//是否分页 sidePagination : 'client',//server:服务器端分页|client:前端分页 pageSize : 4,//单页记录数 pageList : [ 5, 10, 20, 30 ],//可选择单页记录数 showRefresh : true,//刷新按钮 queryParams : function(params) {//上传服务器的参数 var temp = {//如果是在服务器端实现分页,limit、offset这两个参数是必须的 limit : params.limit, // 每页显示数量 offset : params.offset, // SQL语句起始索引 //page : (params.offset / params.limit) + 1, //当前页码 Name : $('#search_name').val(), Tel : $('#search_tel').val() }; return temp; }, columns : [ { title : '登录名', field : 'loginName', sortable : true }, { title : '姓名', field : 'name', sortable : true }, { title : '手机号', field : 'tel', }, { title : '性别', field : 'sex', formatter : formatSex,//对返回的数据进行处理再显示 }, { title : '操作', field : 'id', formatter : operation,//对资源进行操作 } ] }) //value代表该列的值,row代表当前对象 function formatSex(value, row, index) { return value == 1 ? "男" : "女"; //或者 return row.sex == 1 ? "男" : "女"; } //删除、编辑操作 function operation(value, row, index) { var htm = "<button>删除</button><button>修改</button>" return htm; } //查询按钮事件 $('#search_btn').click(function() { $('#mytab').bootstrapTable('refresh', { url : 'user/getUserListPage' }); })
4: bootstrap-table implements front-end paging
▶ Modify some attributes in the JS paging code
sidePagination:'client', queryParams : function (params) { var temp = { name:$('#search_name').val(), tel:$('#search_tel').val() }; return temp; },
▶ Define user Object
package com.debo.common; public class User { private Integer id; private String loginName; private String name; private String tel; private Integer sex; //省略Get/Set函数 }
▶ Server Controller layer code
/** *直接一次性查出所有的数据,返回给前端,bootstrap-table自行分页 */ @RequestMapping("/getUserListPage") @ResponseBody public List<User> getUserListPage(User user,HttpServletRequest request){ List<User> list = userService.getUserListPage(user); return list; }
▶ mabatis statement
<select id="getUserListPage" resultType="com.debo.common.User"> SELECT * FROM user WHERE 1 = 1 <if test="name!=null and name !=''"> AND name LIKE CONCAT('%',#{name},'%') </if> <if test="tel!=null and tel !=''"> AND tel = #{tel} </if> </select>
5: bootstrap-table implements server-side paging
▶ Set some properties in the JS paging code
sidePagination:'server', queryParams : function (params) { var temp = { limit : params.limit, // 每页显示数量 offset : params.offset, // SQL语句起始索引 page: (params.offset / params.limit) + 1, //当前页码 Name:$('#search_name').val(), Tel:$('#search_tel').val() }; return temp; },
▶ Encapsulate the public page object and let the user object inherit the page object
package com.debo.common; public class Page { //每页显示数量 private int limit; //页码 private int page; //sql语句起始索引 private int offset; public int getLimit() { return limit; } public void setLimit(int limit) { this.limit = limit; } public int getPage() { return page; } public void setPage(int page) { this.page = page; } public int getOffset() { return offset; } public void setOffset(int offset) { this.offset = offset; } }
package com.debo.common; public class User extends Page{ private Integer id; private String loginName; private String name; private String tel; private Integer sex; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getLoginName() { return loginName; } public void setLoginName(String loginName) { this.loginName = loginName; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getTel() { return tel; } public void setTel(String tel) { this.tel = tel; } public Integer getSex() { return sex; } public void setSex(Integer sex) { this.sex = sex; } }
▶ Encapsulate the returned data entity class
package com.debo.common; import java.util.ArrayList; import java.util.List; public class PageHelper<T> { //实体类集合 private List<T> rows = new ArrayList<T>(); //数据总条数 private int total; public PageHelper() { super(); } public List<T> getRows() { return rows; } public void setRows(List<T> rows) { this.rows = rows; } public int getTotal() { return total; } public void setTotal(int total) { this.total = total; } }
▶Server Controller layer code
@RequestMapping("/getUserListPage") @ResponseBody public PageHelper<User> getUserListPage(User user,HttpServletRequest request) { PageHelper<User> pageHelper = new PageHelper<User>(); // 统计总记录数 Integer total = userService.getTotal(user); pageHelper.setTotal(total); // 查询当前页实体对象 List<User> list = userService.getUserListPage(user); pageHelper.setRows(list); return pageHelper; }
▶ mybatis statement
<select id="getTotal" resultType="int"> SELECT count(1) FROM user WHERE 1 = 1 <if test="name!=null and name !=''"> AND name LIKE CONCAT('%',#{name},'%') </if> <if test="tel!=null and tel !=''"> AND tel = #{tel} </if> </select> <select id="getUserListPage" resultType="com.debo.common.User"> SELECT * FROM user WHERE 1 = 1 <if test="name!=null and name !=''"> AND name LIKE CONCAT('%',#{name},'%') </if> <if test="tel!=null and tel !=''"> AND tel = #{tel} </if> LIMIT #{offset},#{limit} </select>
tip: Reload the table after adding, deleting or modifying operations
$("#mytab").bootstrapTable('refresh', {url : url});
