前后端結(jié)合實現(xiàn)amazeUI分頁，代碼如下所示；
借鑒
本文在博客https://blog.csdn.net/brave_coder/article/details/52367124的基礎(chǔ)上實現(xiàn)的，非常感謝大佬的分享。
前端實現(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);
//計算按鈕的總個數(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，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>";
//組裝向上一個節(jié)點和下一頁節(jié)點
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個的時候，那么在第五個和倒數(shù)第五個時，執(zhí)行
output += preBar;
output += "<li><a yxhref=\&;" + opts.url + 1 + "\&;>" + 1 + "</a></li>";
//第一個
output += "<li><span>...</span></li>"; //省略號
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;
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)第四個時候
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！");
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
//動態(tài)加dom節(jié)點
}
});
}else{
}
},
error: function (err) {
}
});
后端實現(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)置返回數(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;
}
