AngularJS 简介
AngularJS优点:
<!DOCTYPE html> <html ng-app=""> <head lang="en"> <Meta charset="UTF-8"> <link rel="stylesheet" href="css/foundation.min.css"/> <title></title> </head> <body style="padding:10px;"> <input type="text" ng-model="data.msg"/> <div ng-show="1==1" class="{{data.msg}}">我是一个{{data.msg}}</div> </body> <script src="js/angular.min.js"></script> </html>
2.开发和调试工具的使用
3.第一个 AngularJS Web 应用
<!DOCTYPE html> <html lang="en" ng-app = "todoList"> <head> <Meta charset="UTF-8"> <title>todoList</title> <link rel = "stylesheet" type="text/css" href="css/bootstrap.min.css"> </head> <body style="padding: 10px;" ng-controller="TaskCtrl"> <div class="input-group"> <input type="text" class="form-control" ng-model="task"> <span class="input-group-btn"> <button class = "btn btn-default" ng-click="add()">提交</button> </span> </div> <h4 ng-if="tasks.length>0">任务列表</h4> <ul class = "list-group-item"> <li ng-repeat="item in tasks track by $index" class="list-group-item">{{item}} <a ng-click = "tasks.splice($index,1)">删除</a> </li> </ul> </body> <script src="js/angular.min.js"></script> <script type="text/javascript"> angular.module('todoList',[]) .controller('TaskCtrl',function($scope) { $scope.task = ""; $scope.tasks = []; $scope.add = function () { $scope.tasks.push($scope.task); } }) </script> </html>
2.AngularJS进阶
2.1 AngularJS前端MVC的设计与搭建
MVC模式(Model–view–controller)是软件工程中的一种软件架构模式,把软件系统分为三个基本部分:模型(Model)、视图(View)和控制器(Controller)。
2.2 Binding 指令实现双向数据绑定
<!DOCTYPE html> <html lang="en"> <head> <Meta charset="UTF-8"> <title>AngularJS进阶</title> </head> <body style="padding: 10px;" ng-app=""> <div> <h1>{{2+2}}</h1> <input type="text" ng-model="uname"> <h1 ng-bind="uname">{{uname}}</h1> <h1 ng-clock class="ng-clock">{{uname}}</h1> <h1>{{uname}}</h1> <div class="{{uname}}">{{'用户名:'+uname}}</div> </div> </body> <script src="js/angular.min.js"></script> </html>
ng-bind:https://docs.angularjs.org/ap...
(bind 绑定)
2.3 Controllers 的使用
<!DOCTYPE html> <html lang="en"> <head> <Meta charset="UTF-8"> <title>AngularJS 进阶</title> </head> <body style="padding: 10px" ng-app="app"> <div ng-controller="FirstCtrl"> <input type="text" ng-model="msg"> <h1 ng-bind="msg"></h1> </div> <div ng-controller="NextCtrl"> <input type="text" ng-model="msg"> <h1>{{msg}}</h1> </div> </body> <script src="js/angular.min.js"></script> <script src="js/myctrl.js"></script> </html>
2.4 在$scope中变量和方法的使用
<!DOCTYPE html> <html lang="en"> <head> <Meta charset="UTF-8"> <title>AngularJS进阶</title> <link rel = "stylesheet" type="text/css" href="css/foundation.css"> </head> <body style="padding: 10px" ng-app="app"> <div ng-controller="MyCtrl"> <input type="text" ng-model="user.uname"> <input type="text" ng-model="user.pwd"> <!--<h1>{{reverse()}}</h1>--> <div class="button" ng-click="login()">登录</div> <div ng-show='errormsg.length>0' class="alert-Box">{{errormsg}}</div> </div> </body> <script src="js/angular.min.js"></script> <script src="js/myctrl.js"></script> </html>
angular.module('app',[]) .controller('FirstCtrl',function($scope){ $scope.msg="hello angular"; }) .controller('NextCtrl',function($scope) { $scope.msg="hello angular"; }) .controller('MyCtrl',function($scope) { $scope.msg='ddd'; $scope.errormsg=''; $scope.reverse=function () { return $scope.msg.split("").reverse().join(""); } $scope.login=function () { if($scope.user.uname=="admin" && $scope.user.pwd=="123"){ alert("登陆成功"); } else{ $scope.errormsg="用户名或密码错误" } } })
3. AngularJS进阶-Services与指令的运用
3.1 自定义Sevices服务
<!DOCTYPE html> <html lang="en"> <head> <Meta charset="UTF-8"> <title>AngularJS 进阶</title> <link rel="stylesheet" href="css/foundation.css"> </head> <body style="padding: 10px;" ng-app="app"> <div ng-controller="Myctrl"> <h1>{{msg}}</h1> <h1>{{realname}}</h1> <h1>{{http}}</h1> <h2>{{data.msg}}</h2> <h2>{{uname}}</h2> </div> <script src="js/angular.min.js"></script> <script src="js/app.js"></script> </body> </html>
angular.module('app',[]) .value('realname','zhaoliu') // 是可以改变值的 .constant('http','www.baidu.com') .factory('Data',function () { return{ msg: '你好啊',setMsg:function () { this.msg="我不好"; } } }) .service('User',function () { this.firstname="上官"; this.lastname="飞燕"; this.getName=function () { return this.firstname+this.lastname; } }) .controller('Myctrl',function ($scope,realname,http,Data,User) { $scope.msg="你好"; $scope.realname=realname; $scope.http=http; $scope.data=Data; Data.setMsg(); $scope.uname=User.getName(); });
3.2 Services的应用
<!DOCTYPE html> <html lang="en"> <head> <Meta charset="UTF-8"> <title>AngularJS 进阶</title> </head> <body style="padding:10px;" ng-app="app"> <div ng-controller="Fctrl"> <input type="text" ng-model="data.msg"> <h2>{{data.msg}}</h2> </div> <div ng-controller="Sctrl"> <input type="text" ng-model="data.msg"> <h2>{{data.msg}}</h2> </div> </body> <script src="js/angular.min.js"></script> <script src="js/app.js"></script> </html>
angular.module('app',[]) .factory('Data',function () { return { msg:'我来自factory'; shopcart:['1','2'] } }) // 公共容器 .controller('Fctrl',Data) { //下单ctrl $scope.data=Data }) .controller('Sctrl',Data) { // 购物车 $scope.data=Data })
3.3 常用指令的使用
ng-if
会把元素从dom中移除,ng-show/hide
不会。
// ng-bind,{{}},ng-model,ng-show/hide,ng-if // ng-checked,ng-src,ng-href,ng-class,ng-selected,ng-submit,ng-disabled angular.module('app',[]) .controller('UserCtrl',function ($scope) { $scope.user={ isShowImg:true,showicon: true,icon: 'image/logo.jpg',uname: '',pwd: '',zw: '1',sex: '0',aihao: [1] }; $scope.isChecked=function (n) { var isok = false; for(var i = 0;i< $scope.user.aihao.lrngth;i++){ if(n == $scope.user.aihao[i]){ isok=true; break; } } return isok; } $scope.register=function (u) { console.log(u); } })
3.4 常用指令ng-repeat的使用
<!DOCTYPE html> <html lang="en"> <head> <Meta charset="UTF-8"> <title>AngualrJS</title> <link rel = "stylesheet" type="text/css" href="css/foundation.min.css"> </head> <body ng-app="app" ng-controller="AddressCtrl"> <div style="padding:10px;font-weight:bold">地址管理</div> <ul class="ui-list ui-list-link ui-list-text ul-list-active ui-border-tb"> <li ng-repeat="a in list" class="ui-border-t"> <h4>{{$index + 1 + '.' + a.address + $first + ' ' + $last}}</h4> </li> </ul> <br> <ul> <li ng-repeat="a in list" class="ui-border-t"> <h4 ng-if="!$last">{{$index+1+'.'+a.address}}</h4> </li> </ul> <br> <ul> <li ng-repeat="a in list" class="ui-border-t" ng-if="!$last"> <h4>{{$index + 1 + '.' + a.address}}</h4> </li> </ul> <br> <ul class="ui-list ui-list-link ui-list-text ul-list-active ui-border-tb"> <li ng-repeat="a in list" ng-class="{'selected':$first}"> <h4>{{$index + 1 + '.' + a.address}}</h4> </li> </ul> </body> <script src="js/angular.min.js"></script> <script src="js/app.js"></script> </html>
angular.module('app',[]) .controller('AddressCtrl',function ($scope) { $scope.list = [ {id:1,address:'莲湖小区14栋2层'},{id:2,address:'建设小区14栋2层'},{id:3,address:'兴化路89号'},{id:4,address:'北京鸟巢好远的地方'} ]; })
4.AngularJS内置服务$http的使用
4.1 使用$http查询MysqL数据
angular.module('app',[]) .config(function ($httpProvider) { }) .controller('MyCtrl',$http) { $http.get('http://127.0.0.0.1:80/user/getUsers') .success(function (resp) { console.log(resp); }) })
4.2 $http实现对数据的增删改
<!DOCTYPE html> <html lang="en"> <head> <Meta charset="UTF-8"> <title>AngularJS 进阶$http</title> <link rel="stylesheet" href="css/foundation.min.css"> <style type="text/css"> html,body{font-size: 14px;} </style> </head> <body style="padding: 10px;" ng-app="app"> <div ng-controller="Myctrl"></div> <input type="text" ng-model="id"> <input type="text" ng-model="name"> <button class="button" ng-click="adduser()">添加</button> <button class="button" ng-click="deluser()">删除</button> </body> <script src="js/angular.min.js"></script> <script src="js/app.js"></script> </html>
angular.module('app',$http) { $scope.id = ""; $scope.name=""; $scope.adduser = function(){ $http.get('http://127.0.0.0.1:80/user/getUsers',{id:$scope.id,name:$scope.name}) .success(function (resp) { if (resp.success) { alert("添加成功"); } }) } $scope.deluser=function () { $http.post('http://127.0.0.1:80/user/delUser',{id:$scope.id}) .success(function () { if(resp.success){ alert('删除成功'); } }) } })
// UserController.java import java.util.List; import com.jfinal.core.Controller; import com.model.User; public class UserController extends Controller{ public void getUser(){ List<User> Users = User.dao.find("select * from t_user"); renderJson(users); } public void addusers(){ String name = getPara("name"); User user = new User(); boolean isok = user.set("name",name).save(); renderJson("success",isok); } public void delUser(){ String id = getPara("id"); boolean isok = User.dao.deleteById(id); renderJson("success",isok); } }
