<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <div ng-app="myApp" ng-controller="personCtrl"> <button ng-click="toggle()">隐藏/显示</button> //ng-click里面是一个toggle()函数 <p ng-hide="myVar"> 名: <input type=text ng-model="firstName"><br> 姓: <input type=text ng-model="lastName"><br><br> 姓名: {{firstName + " " + lastName}} </p> </div> <script> var app = angular.module('myApp', []); app.controller('personCtrl', function($scope) { $scope.firstName = "John"; $scope.lastName = "Doe"; $scope.myVar = false; $scope.toggle = function() { //tpggle后面没有() $scope.myVar = !$scope.myVar; //用于切换myVar的值 } }); </script> </body> </html>
应用解析:
第一部分 personController与控制器章节类似。
应用有一个默认属性: $scope.myVar = false;
ng-hide 指令设置 <p>元素及两个输入域是否可见， 根据 myVar 的值 (true 或 false) 来设置是否可见。
toggle() 函数用于切换 myVar 变量的值（true 和 false）。
