怎么通過(guò)前后端結(jié)合實(shí)現(xiàn)amazeUI分頁(yè)效果？amazeUI使用分頁(yè)案例詳解！

對(duì)于現(xiàn)在我們的編程開(kāi)發(fā)我們都是盡可能的做到前后端結(jié)合開(kāi)發(fā)，根據(jù)這個(gè)開(kāi)頭接下來(lái)小編就來(lái)和大家說(shuō)說(shuō)有關(guān)于：“怎么通過(guò)前后端結(jié)合實(shí)現(xiàn)amazeUI分頁(yè)效果？”這個(gè)問(wèn)題的相關(guān)內(nèi)容分享！

借鑒

本文在博客https://blog.csdn.net/brave_coder/article/details/52367124的基礎(chǔ)上實(shí)現(xiàn)的，非常感謝大佬的分享。

前端實(shí)現(xiàn)

1、引入paginator.js

(function ($) {
    $.fn.paginator = function (options) {
        //this指向當(dāng)前的選擇器
        var config = {
            url: "",
            pageParent: "",
            totalBars: -1,
            limit: -1,
            offset: 1,
            callback: null
        }
        //合并參數(shù)
        var opts = $.extend(config, options);
 
        opts.totalBars = Math.ceil(opts.totalBars / opts.limit);
        //計(jì)算按鈕的總個(gè)數(shù)
 
        //獲取offset參數(shù)
        var queryString = function (url) {
            var offset = (url.split("?")[1]).split("=")[1];
            return parseInt(offset);
        }
 
        //ajax核心方法，用于分頁(yè)的數(shù)據(jù)操作
        var ajaxCore = function (offset, fn) {
            $.ajax({
                "url": opts.url,

                },
                "dataType": "JSON",
                "method": "POST",
                "success": fn
            });
        }

                        for (var j = 4; j >= 0; j--) {

        var clear = function () {

        }
 
 
        //初始化裝配分頁(yè)按鈕
        var init = function (fn) {
            if (typeof (fn) != "function") {
                console.log("將不能正確的執(zhí)行回調(diào)函數(shù)");

            var preBar = "<li class="am-disabled"><a yxhref="javascript:;">?</a></li>";
            //上一頁(yè),（禁用的效果）
            //如果只有一頁(yè)，那么禁用下一頁(yè)
            var nextBar = opts.totalBars > 1 ? "<li><a yxhref="" + opts.url + 2 + "">?</a></li>" : "<li class="am-disabled"><a yxhref="javascript:;">?</a></li>";
            //最后一頁(yè)
            var output = "<li class="am-active"><a yxhref="" + opts.url + 1 + "">1</a></li>";
 
            if (opts.totalBars <= 7) {
                for (var i = 1; i < opts.totalBars; i++) {
                    output += "<li><a yxhref="" + opts.url + (i + 1) + "">" + (i + 1) + "</a></li>";
                }
            } else {
                for (var j = 1; j < 5; j++) {
                    output += "<li><a yxhref="" + opts.url + (j + 1) + "">" + (j + 1) + "</a></li>";
                }

            }
            $(opts.pageParent).delegate("a","click", function () {
                var offset = queryString($(this).attr("yxhref"));
                console.log("ok");
                pageCore(offset);
            });
            $(opts.pageParent).append(preBar + output + nextBar);
        };
        init(opts.callback);//初始化分頁(yè)引擎
    }
}(window.jQuery))

2、獲取總頁(yè)數(shù)，再獲取分頁(yè)：

$.ajax({
        type: "GET",
        url: selectSendNumberNumsByContURL,//獲取總數(shù)
        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節(jié)點(diǎn)
                        
                        //動(dòng)態(tài)加dom節(jié)點(diǎn)
                    }
                });
            }else{

            }
        },
        error: function (err) {

        }
    });

后端實(shí)現(xiàn)（分頁(yè)）

這里是controller，拿到offset（第幾頁(yè)）參數(shù)、limit（每頁(yè)多少數(shù)量），再寫(xiě)SQL實(shí)現(xiàn)分頁(yè)就好了。

@RequestMapping(value = "/selectNumberCheckByCont", method = RequestMethod.POST)
    @ResponseBody
    public List<ReturnUtils> selectNumberCheckByCont(HttpServletRequest request,
                                                     HttpServletResponse response) throws Exception {

        //統(tǒng)一設(shè)置返回?cái)?shù)據(jù)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<ReturnUtils> list = iNumberCheckService.selectNumberCheckByCont(offset, limit);

        return list;
    }
