AngularJS and BootStrap imitate Baidu's paging method
This article mainly introduces the sample code of AngularJS and BootStrap to imitate Baidu paging. Pagination can be used many times. Now I share it with you and give it as a reference.
Imitates Baidu’s display of 10 pieces of data per page, and implements the algorithm of centering the current page.

var paginationApp = angular.module("paginationApp", []);
paginationApp.controller("paginationCtrl", ["$scope", "$http",
function($scope, $http) {
// 分页组件 必须变量
$scope.currentPage = 1; // 当前页 （请求数据）
$scope.pageSize = 4; // 每页记录数 （请求数据）
$scope.totalCount = 0; // 总记录数 （响应数据）
$scope.totalPages = 0; // 总页数 （根据 总记录数、每页记录数 计算 ）
// 要在分页工具条显示所有页码
$scope.pageList = new Array();
// 加载上一页数据
$scope.prev = function(){
$scope.selectPage($scope.currentPage-1);
}
// 加载下一页数据
$scope.next = function(){
$scope.selectPage($scope.currentPage+1);
}
// 加载指定页数据
$scope.selectPage = function(page) {
// page 超出范围
if($scope.totalPages != 0 && (page < 1 || page > $scope.totalPages)){
return ;
}
$http({
method: 'GET',
url: '6_'+page+'.json',
params: {
"page" : page , // 页码
"pageSize" : $scope.pageSize // 每页记录数
}
}).success(function(data, status, headers, config) {
// 显示表格数据
$scope.products = data.products;
// 根据总记录数 计算 总页数
$scope.totalCount = data.totalCount;
$scope.totalPages = Math.ceil($scope.totalCount / $scope.pageSize);
// 更新当前显示页码
$scope.currentPage = page ;
// 显示分页工具条中页码
var begin ; // 显示第一个页码
var end ; // 显示最后一个页码
// 理论上 begin 是当前页 -5
begin = $scope.currentPage - 5 ;
if(begin < 1){ // 第一个页码 不能小于1
begin = 1 ;
}
// 显示10个页码，理论上end 是 begin + 9
end = begin + 9;
if(end > $scope.totalPages ){// 最后一个页码不能大于总页数
end = $scope.totalPages;
}
// 修正begin 的值, 理论上 begin 是 end - 9
begin = end - 9;
if(begin < 1){ // 第一个页码 不能小于1
begin = 1 ;
}
// 要在分页工具条显示所有页码
$scope.pageList = new Array();
// 将页码加入 PageList集合
for(var i=begin ; i<= end ;i++){
$scope.pageList.push(i);
}
}).error(function(data, status, headers, config) {
// 当响应以错误状态返回时调用
alert("出错，请联系管理员 ");
});
}
// 判断是否为当前页
$scope.isActivePage = function(page) {
return page === $scope.currentPage;
}
// 初始化，选中第一页
$scope.selectPage(1);
}
]);

1_1.json
{
"totalCount":100,
"products":[
{"id":"1001","name":"苹果手机","price":"5000"},
{"id":"1002","name":"三星手机","price":"6000"}
]
}
1_2.json

"totalCount":100,
"products":[
{"id":"1001","name":"华为手机","price":"5000"},
{"id":"1002","name":"vivo手机","price":"6000"}

}
The effect achieved is as shown in the figure:
// 将页码加入 PageList集合
for(var i=begin ; i<= end ;i++){
$scope.pageList.push(i);
}
As shown in the figure below
<li ng-repeat="page in pageList" ng-class="{active: isActivePage(page)}">
<a href ng-click="selectPage(page)">{{page}}</a>
</li>

Javascript Data Types : Is there any difference between Browser and NodeJs?May 14, 2025 am 12:15 AMJavaScript core data types are consistent in browsers and Node.js, but are handled differently from the extra types. 1) The global object is window in the browser and global in Node.js. 2) Node.js' unique Buffer object, used to process binary data. 3) There are also differences in performance and time processing, and the code needs to be adjusted according to the environment.

Python vs. JavaScript: A Comparative Analysis for DevelopersMay 09, 2025 am 12:22 AMThe main difference between Python and JavaScript is the type system and application scenarios. 1. Python uses dynamic types, suitable for scientific computing and data analysis. 2. JavaScript adopts weak types and is widely used in front-end and full-stack development. The two have their own advantages in asynchronous programming and performance optimization, and should be decided according to project requirements when choosing.
Python vs. JavaScript: Choosing the Right Tool for the JobMay 08, 2025 am 12:10 AMWhether to choose Python or JavaScript depends on the project type: 1) Choose Python for data science and automation tasks; 2) Choose JavaScript for front-end and full-stack development. Python is favored for its powerful library in data processing and automation, while JavaScript is indispensable for its advantages in web interaction and full-stack development.
Python and JavaScript: Understanding the Strengths of EachMay 06, 2025 am 12:15 AMPython and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.

JavaScript Applications: From Front-End to Back-EndMay 04, 2025 am 12:12 AMJavaScript can be used for front-end and back-end development. The front-end enhances the user experience through DOM operations, and the back-end handles server tasks through Node.js. 1. Front-end example: Change the content of the web page text. 2. Backend example: Create a Node.js server.
Python vs. JavaScript: Which Language Should You Learn?May 03, 2025 am 12:10 AMChoosing Python or JavaScript should be based on career development, learning curve and ecosystem: 1) Career development: Python is suitable for data science and back-end development, while JavaScript is suitable for front-end and full-stack development. 2) Learning curve: Python syntax is concise and suitable for beginners; JavaScript syntax is flexible. 3) Ecosystem: Python has rich scientific computing libraries, and JavaScript has a powerful front-end framework.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
