前端实现

1、引入paginator.js

(function ($) {
    $.fn.paginator = function (options) {
        //this指向当前的选择器
        var config = {
            url: "",
            pageParent: "",
            totalBars: -1,
            limit: -1,
            offset: 1,
            callback: null
        }
        //合并参数
        var opts = $.extend(config, options);
 
        opts.totalBars = Math.ceil(opts.totalBars / opts.limit);
        //计算按钮的总个数
 
        //获取offset参数
        var queryString = function (url) {
            var offset = (url.split("?")[1]).split("=")[1];
            return parseInt(offset);
        }
 
        //ajax核心方法,用于分页的数据操作
        var ajaxCore = function (offset, fn) {
            $.ajax({
                "url": opts.url,
                "data": {
                    "offset": offset,
                    "limit": opts.limit
                },
                "dataType": "JSON",
                "method": "POST",
                "success": fn
            });
        }
 
        //重新装配分页按钮
        var pageCore = function (offset) {
            if (opts.offset == offset) {
                return;
            } //如果是当前页面,那么就什么事都不用干了!
            else {
                ajaxCore(offset, opts.callback);
                $(opts.pageParent).empty();
                //否则,清空所有的节点,重新向DOM插入新的分页按钮
                var output = "";
                var nextBar = offset == opts.totalBars ? "»" : "
  • »
  • ";                 var preBar = offset == 1 ? "«" : "
  • «
  • ";                 //组装向上一个节点和下一页节点                 if (opts.totalBars > 7) {                     if (offset < 5) {                         output += preBar;                         for (var i = 1; i <= 5; i++) {                             if (i == offset) {                                 output += "" + offset + "";                             } else {                                 output += "
  • " + i + "
  • ";                             }                         }                         output += "
  • ...
  • ";                         output += "
  • " + (opts.totalBars) + "
  • " + nextBar;                     } else if (offset >= 5 && offset <= opts.totalBars - 4) {                         //当页面大于7个的时候,那么在第五个和倒数第五个时,执行                         output += preBar;                         output += "
  • " + 1 + "
  • ";                         //第一个                         output += "
  • ...
  • "; //省略号                           output += "
  • " + (offset - 1) + "
  • ";                           output += "" + offset + "";                           output += "
  • " + (offset + 1) + "
  • ";                           output += "
  • ...
  • "; //省略号;                           output += "
  • " + (opts.totalBars) + "
  • "; //尾页                           output += nextBar;                       } else if (offset > opts.totalBars - 4 && offset <= opts.totalBars) {                         //当页面位于倒数第四个时候                         output += preBar;                         output += "
  • " + 1 + "
  • " + "
  • ...
  • ";                           for (var j = 4; j >= 0; j--) {                             if (opts.totalBars - j == offset) {                                 output += "" + (opts.totalBars - j) + "";                             } else {                                 output += "
  • " + (opts.totalBars - j) + "
  • ";                             }                         }                         output += nextBar;                     } else {                         console.log("分页数据出错!");                         return;                     }                 } else {                     output += preBar;                     for (var i = 1; i <= opts.totalBars; i++) {                         if (i == offset) {                             output += "" + offset+ "";                         } else {                             output += "
  • " + i+ "
  • ";                         }                     }                     output += nextBar;                 }                 $(opts.pageParent).append(output);                 opts.offset = offset; //将偏移量赋值给config里面的offset             }         }           //清理函数,防止多绑定事件和重新计算分页         var clear = function () {             $(opts.pageParent).empty().undelegate();         }             //初始化装配分页按钮         var init = function (fn) {             if (typeof (fn) != "function") {                 console.log("将不能正确的执行回调函数");             } else {                 opts.callback = fn;             }             clear();             ajaxCore(1, opts.callback);//执行初始化ajax方法             var preBar = "«";             //上一页,(禁用的效果)             //如果只有一页,那么禁用下一页             var nextBar = opts.totalBars > 1 ? "
  • »
  • " : "»";             //最后一页             var output = "1";               if (opts.totalBars <= 7) {                 for (var i = 1; i < opts.totalBars; i++) {                     output += "
  • " + (i + 1) + "
  • ";                 }             } else {                 for (var j = 1; j < 5; j++) {                     output += "
  • " + (j + 1) + "
  • ";                 }                 output += "
  • ...
  • ";                 output += "
  • " + (opts.totalBars) + "
  • ";             }             $(opts.pageParent).delegate("a","click", function () {                 var offset = queryString($(this).attr("yxhref"));                 console.log("ok");                 pageCore(offset);             });             $(opts.pageParent).append(preBar + output + nextBar);         };         init(opts.callback);//初始化分页引擎     } }(window.jQuery))

    2、获取总页数,再获取分页

    $.ajax({
            type: "GET",
            url: selectSendNumberNumsByContURL,//获取总数
            data: {},
            dataType: "json",
            success: function(data){
    
                if (data[0].code == 200) {
    
                    $("#paginator").paginator({
                        url: selectSendNumberByContURL + "?offsets=",
                        pageParent: "#paginator",
                        totalBars: data[0].allNums,
                        limit: 10,
                        offset: 1,
                        callback: function (data1) {
    
                            //清空DOM节点
                            
                            //动态加dom节点
                        }
                    });
                }else{
    
                }
            },
            error: function (err) {
    
            }
        });

    后端实现(分页)

    这里是controller,拿到offset(第几页)参数、limit(每页多少数量),再写SQL实现分页就好了。

    @RequestMapping(value = "/selectNumberCheckByCont", method = RequestMethod.POST)
        @ResponseBody
        public List selectNumberCheckByCont(HttpServletRequest request,
                                                         HttpServletResponse response) throws Exception {
    
            //统一设置返回数据格式
            response.setContentType("application/json");
            response.setHeader("Pragma", "no-cache");
            response.setCharacterEncoding("UTF-8");
    
            String offset = request.getParameter("offset");
            String limit = request.getParameter("limit");
    
            List list = iNumberCheckService.selectNumberCheckByCont(offset, limit);
    
            return list;
        }
