使用<span ng-bind="word.name"></span>,World!取代原来是{{}}可绑定数据，刷新看不到过程。

简单数据的填充绑定：

var userInfoModule = angular.module('userInfoModule',[]);userInfoModule.controller('UserInfoCtrl',['$scope',function($scope){$scope.userInfo = {email:"902901290@qq.com",password:"123123",autoLogin:true};$scope.getFormData=function(){console.log($scope.userInfo);};$scope.setFormData=function(){$scope.userInfo={email:'fuck@qq.com',password:'123',autoLogin:false}};$scope.resetForm = function (){$scope.userInfo={email:"902901290@qq.com",password:"123123",autoLogin:true}};}]);

NgClass的使用：

var MyCSSModule = angular.module('MyCSSModule',[]);MyCSSModule.controller('HeaderController',['$scope',function ($scope){$scope.isError  = false;$scope.isWarning = false;$scope.showError = function(){$scope.messageText = 'This is an error!';$scope.isError = true;$scope.isWarning = false;}; $scope.showWarning = function(){$scope.messageText = 'Just a warning,Please carry on.';$scope.isError = false;$scope.isWarning = true;}; }])

<div ng-controller="HeaderController"><div ng-class='{error:isError,warning:isWarning}'>{{messageText}}</div><button ng-click='showError()'>Simulate Error</button><button ng-click='showWarning()'>Simulate Warning</button></div>

NgShow的使用：

var MyCSSModule = angular.module('MyCSSModule',[]);MyCSSModule.controller('DeathrayMenuController',['$scope',function ($scope){$scope.menuState = {show:false};$scope.toggleMenu = function (){$scope.menuState.show = !$scope.menuState.show;};}])

<div ng-controller='DeathrayMenuController'><button ng-click='toggleMenu()'>Toggle Menu</button><ul ng-show='menuState.show'><li ng-click='stun()'>Stun</li><li ng-click='disintegrate()'>disintegrate</li><li ng-click='erase()'>erase from history</li></ul></div>
