前后端结合实现amazeUI分页,代码如下所示;
借鉴
本文在博客https://blog.csdn.net/brave_coder/article/details/52367124的基础上实现的,非常感谢大佬的分享。
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 ? "<li class=\"am-disabled\"><a yxhref=\"javascript:;\">»</a></li>" : "<li><a yxhref=\"" + opts.url + (offset + 1) + "\">»</a></li>"; var preBar = offset == 1 ? "<li class=\"am-disabled\"><a yxhref=\"javascript:;\">«</a></li>" : "<li><a yxhref=\"" + opts.url + (offset - 1) + "\">«</a></li>"; //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 += "<li class=\"am-active\"><a yxhref=\"" + opts.url + offset + "\">" + offset + "</a></li>"; } else { output += "<li><a yxhref=\"" + opts.url + i + "\">" + i + "</a></li>"; } } output += "<li><span>...</span></li>"; output += "<li><a yxhref=\"" + opts.url + (opts.totalBars) + "\">" + (opts.totalBars) + "</a></li>" + 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 += "<li><a yxhref=\"" + opts.url + 1 + "\">" + 1 + "</a></li>"; //第一个 output += "<li><span>...</span></li>"; //省略号 output += "<li><a yxhref=\"" + opts.url + (offset - 1) + "\">" + (offset - 1) + "</a></li>"; output += "<li class=\"am-active\"><a yxhref=\"" + opts.url + offset + "\">" + offset + "</a></li>"; output += "<li><a yxhref=\"" + opts.url + (offset + 1) + "\">" + (offset + 1) + "</a></li>"; output += "<li><span>...</span></li>"; //省略号; output += "<li><a yxhref=\"" + opts.url + (opts.totalBars) + "\">" + (opts.totalBars) + "</a></li>"; //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 += "<li><a yxhref=\"" + opts.url + 1 + "\">" + 1 + "</a></li>" + "<li><span>...</span></li>"; for (var j = 4; j >= 0; j--) { if (opts.totalBars - j == offset) { output += "<li class=\"am-active\"><a yxhref=\"" + opts.url + (opts.totalBars - j) + "\">" + (opts.totalBars - j) + "</a></li>"; } else { output += "<li><a yxhref=\"" + opts.url + (opts.totalBars - j) + "\">" + (opts.totalBars - j) + "</a></li>"; } } 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 += "<li class=\"am-active\"><a yxhref=\"" + opts.url + offset + "\">" + offset+ "</a></li>"; } else { output += "<li><a yxhref=\"" + opts.url + i + "\">" + i+ "</a></li>"; } } 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 = "<li class=\"am-disabled\"><a yxhref=\"javascript:;\">«</a></li>"; //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 ? "<li><a yxhref=\"" + opts.url + 2 + "\">»</a></li>" : "<li class=\"am-disabled\"><a yxhref=\"javascript:;\">»</a></li>"; //最后一页 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>"; } output += "<li><span>...</span></li>"; output += "<li><a yxhref=\"" + opts.url + (opts.totalBars) + "\">" + (opts.totalBars) + "</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<ReturnUtils> 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<ReturnUtils> list = iNumberCheckService.selectNumberCheckByCont(offset, limit); return list; }
