<!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）。
