這篇文章給大家分享的是有關(guān)前后端結(jié)合怎么實(shí)現(xiàn)amazeUI分頁效果的內(nèi)容。小編覺得挺實(shí)用的,因此分享給大家做個(gè)參考,一起跟隨小編過來看看吧。
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,用于分頁的數(shù)據(jù)操作 var ajaxCore = function (offset, fn) { $.ajax({ "url": opts.url, "data": { "offset": offset, "limit": opts.limit }, "dataType": "JSON", "method": "POST", "success": fn }); } //重新裝配分頁按鈕 var pageCore = function (offset) { if (opts.offset == offset) { return; } //如果是當(dāng)前頁面,那么就什么事都不用干了! else { ajaxCore(offset, opts.callback); $(opts.pageParent).empty(); //否則,清空所有的節(jié)點(diǎn),重新向DOM插入新的分頁按鈕 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>"; //組裝向上一個(gè)節(jié)點(diǎn)和下一頁節(jié)點(diǎn) 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) { //當(dāng)頁面大于7個(gè)的時(shí)候,那么在第五個(gè)和倒數(shù)第五個(gè)時(shí),執(zhí)行 output += preBar; output += "<li><a yxhref=\"" + opts.url + 1 + "\">" + 1 + "</a></li>"; //第一個(gè) output += "<li><span>...</span></li>"; //省略號(hào) 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>"; //省略號(hào); output += "<li><a yxhref=\"" + opts.url + (opts.totalBars) + "\">" + (opts.totalBars) + "</a></li>"; //尾頁 output += nextBar; } else if (offset > opts.totalBars - 4 && offset <= opts.totalBars) { //當(dāng)頁面位于倒數(shù)第四個(gè)時(shí)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("分頁數(shù)據(jù)出錯(cuò)!"); 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; //將偏移量賦值給config里面的offset } } //清理函數(shù),防止多綁定事件和重新計(jì)算分頁 var clear = function () { $(opts.pageParent).empty().undelegate(); } //初始化裝配分頁按鈕 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)"); } else { opts.callback = fn; } clear(); ajaxCore(1, opts.callback);//執(zhí)行初始化ajax方法 var preBar = "<li class=\"am-disabled\"><a yxhref=\"javascript:;\">«</a></li>"; //上一頁,(禁用的效果) //如果只有一頁,那么禁用下一頁 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 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);//初始化分頁引擎 } }(window.jQuery))
2、獲取總頁數(shù),再獲取分頁
$.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)
這里是controller,拿到offset(第幾頁)參數(shù)、limit(每頁多少數(shù)量),再寫SQL實(shí)現(xiàn)分頁就好了。
@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; }
