This time I will bring you how to operate users with Angular js. What are the precautions for operating users with Angular js? The following is a practical case, let’s take a look.
nbsp;html> <meta> <title>Title</title> <style> table{ border-collapse: collapse; } th,td{ padding: 10px; border: 1px solid #000000; } </style> <script></script> <script> var myapp = angular.module("myapp",[]); myapp.controller("myCtrl",function ($scope) { $scope.data = [{ "id":1, "name":"张三", "pwd":"123", "age":22, "sex":"男", "check":false }, { "id":2, "name":"李四", "pwd":"456", "age":33, "sex":"男", "check":false }, { "id":3, "name":"王五", "pwd":"789", "age":44, "sex":"女", "check":false }]; $scope.show = false; //添加用户 $scope.add = function () { $scope.show = true; } //添加 $scope.submit = function () { if($scope.name==""){ alert("请输入姓名") }else if($scope.correct==true){ //进行修改的操作 $scope.data[$scope.index].pwd = $scope.pwd; }else{ //添加的操作 $scope.data.push({"name":$scope.name,"pwd":$scope.pwd,"age":$scope.age,"sex":$scope.sex}); $scope.show = false; } } //用户名查询。不能含有敏感字 $scope.search = ""; $scope.search2 =""; //监听输入框的内容 $scope.$watch("search",function (value) { if(value.indexOf("我")!=-1){ alert("含有敏感字"); $scope.search = ""; }else{ $scope.search2 = $scope.search; } }); //年龄筛选 $scope.opt = "请选择"; $scope.ageFilter = function (item) { if($scope.opt!="请选择"){ var opt = $scope.opt; var ageArr = opt.split("-"); var max = ageArr[1]; var min = ageArr[0]; var age = item.age; if(age<min||age>max){ return false; }else{ return true; } }else{ return true; } }; //性别筛选 $scope.sexthis = "请选择"; $scope.sexFun = function (item) { if($scope.sexthis!="请选择"){ //如果性别==男||性别==女 if(item.sex==$scope.sexthis) { return true; }else{ return false; } }else{ return true; } } //全选 $scope.checkAll = false; $scope.checkWhat = function () { if ($scope.checkAll == true) { for (var i = 0; i < $scope.data.length; i++) { $scope.data[i].check = true; } } else { for (var i = 0; i < $scope.data.length; i++) { $scope.data[i].check = false; } } }; //反选 var n = 0; $scope.checkIt =function (index) { console.log(index) if($scope.data[index].check==true){ n++; }else{ n--; } if(n==$scope.data.length){ $scope.checkAll=true; }else{ $scope.checkAll = false; } }; //点击修改密码 $scope.correct = function (index) { $scope.show = true; $scope.name = $scope.data[index].name; $scope.pwd = $scope.data[index].pwd; //写入一个状态值 $scope.correct = true; //记录索引 $scope.index = index; } //全部删除 $scope.delAll = function () { $scope.data.length=0; } //批量删除 $scope.del = function () { for(var i = 0;i<$scope.data.length;i++){ if($scope.data[i].check ==true){ $scope.data.splice(i,1); i--; } } } }) </script> <h2 id="用户信息表">用户信息表</h2> <input> 年龄<select> <option>请选择</option> <option>10-20</option> <option>20-30</option> <option>30-40</option> </select> 性别<select> <option>请选择</option> <option>男</option> <option>女</option> </select> <button>全部删除</button> <button>批量删除</button>

How to use mockjs to simulate back-end data
The above is the detailed content of How to operate users in Angular js. For more information, please follow other related articles on the PHP Chinese website!

The differences in performance and efficiency between Python and JavaScript are mainly reflected in: 1) As an interpreted language, Python runs slowly but has high development efficiency and is suitable for rapid prototype development; 2) JavaScript is limited to single thread in the browser, but multi-threading and asynchronous I/O can be used to improve performance in Node.js, and both have advantages in actual projects.

JavaScript originated in 1995 and was created by Brandon Ike, and realized the language into C. 1.C language provides high performance and system-level programming capabilities for JavaScript. 2. JavaScript's memory management and performance optimization rely on C language. 3. The cross-platform feature of C language helps JavaScript run efficiently on different operating systems.

JavaScript runs in browsers and Node.js environments and relies on the JavaScript engine to parse and execute code. 1) Generate abstract syntax tree (AST) in the parsing stage; 2) convert AST into bytecode or machine code in the compilation stage; 3) execute the compiled code in the execution stage.

The future trends of Python and JavaScript include: 1. Python will consolidate its position in the fields of scientific computing and AI, 2. JavaScript will promote the development of web technology, 3. Cross-platform development will become a hot topic, and 4. Performance optimization will be the focus. Both will continue to expand application scenarios in their respective fields and make more breakthroughs in performance.

Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.

Yes, the engine core of JavaScript is written in C. 1) The C language provides efficient performance and underlying control, which is suitable for the development of JavaScript engine. 2) Taking the V8 engine as an example, its core is written in C, combining the efficiency and object-oriented characteristics of C. 3) The working principle of the JavaScript engine includes parsing, compiling and execution, and the C language plays a key role in these processes.

JavaScript is at the heart of modern websites because it enhances the interactivity and dynamicity of web pages. 1) It allows to change content without refreshing the page, 2) manipulate web pages through DOMAPI, 3) support complex interactive effects such as animation and drag-and-drop, 4) optimize performance and best practices to improve user experience.

C and JavaScript achieve interoperability through WebAssembly. 1) C code is compiled into WebAssembly module and introduced into JavaScript environment to enhance computing power. 2) In game development, C handles physics engines and graphics rendering, and JavaScript is responsible for game logic and user interface.
