这篇文章给大家分享的是有关前后端结合怎么实现amazeUI分页效果的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。

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;
    }
