Ionic,angular.js学习

前端之家收集整理的这篇文章主要介绍了Ionic,angular.js学习前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

ionic start myApp tabs
–在当前目录下创建名为myApp的tabs的项目,可选模板为sidemenu 侧滑、tabs 底部tab切换、blank 空白

ionic platform add android
添加android平台

ionic build android
生成android apk

ionic run android
生成android apk并在模拟器或者真机中调式。

ionic serve –1ab
–在浏览器上显示效果

npm install angular
–在该目录下下载angular.js。生成node_modules文件夹,angular.js和angular.min.js是我们要用的。

初识AngularJS

<!DOCTYPE html> <html> <head> <Meta charset="utf-8" /> <script src="angular.min.js"></script>//引入angularjs <title>lifei</title> </head> <body ng-app="">//告诉浏览器angular.js的作用域,不在该作用域将无效 <p>请输入:</p> <p> <input type="text" ng-model="name"</p>//ng-mode表示将input中输入的值赋值给name <div ng-bind="name"></div>//绑定赋值为name的mode <div>{{name}}</div>//同上 <div ng-init="sex='男'"></div>//定义应用程序初始值 {{sex}} {{3+5}} <div ng-init="a=3;c=5">{{a*c}}</div>//定义应用程序初始值 <div ng-app="" ng-init="person={fistname:'li',lastname:'fei'}"> {{person.lastname}} </div>//输出fei </body> </html> 

AngularJs控制器

<!DOCTYPE html> <html> <head> <Meta charset="utf-8" /> <script src="angular.min.js"></script> <title>lifei</title> </head> <body ng-app="myApp"> <div ng-controller="firstController"> {{firstName}} </div> <div ng-controller="secondController"> {{persons[0].name}} {{persons[1].age}} <ul> <li ng-repeat="p in persons"> 姓名:{{p.name}}</br> 年龄:{{p.age}} </li> </ul> </div> </body> <script type="text/javascript"> var app=angular.module("myApp",[]); //$scope是angularjs控制器和module链接的桥梁 app.controller('firstController',function($scope){ $scope.firstName="li"; $scope.lastName="fei"; }); app.controller("secondController",function($scope){ $scope.persons=[ {name:'lifei',age:'26'},{name:'liran',age:'18'},{name:'lidan',age:'30'} ]; }); </script> </html> 

angularJs url请求及过滤器:

<!DOCTYPE html> <html> <head> <Meta charset="UTF-8"> <script src="angular.min.js"></script> <title></title> </head> <body ng-app="myApp"> <div ng-controller="firstController"></div> <div ng-controller="secondController"> {{price | currency}} <input type="text" ng-model="name" /> {{name | lowercase}}//uppercase转大写 </div> <div ng-controller="thirdController"> <ul> <li ng-repeat="p in persons | orderBy:'age'">//按照年龄排序 姓名:{{p.name}}</br> 年龄:{{p.age}} </li> </ul> </div> </body> <script type="text/javascript"> var app=angular.module("myApp",[]); app.controller("secondController",function($scope){//controller如果在html中声明了,就要在script中出现 $scope.price="12121"; }); var url='myJson.json';//注意跨域请求 app.controller('firstController',function($scope,$http){ $http.get(url).success(function(data){ console.log(data); }).error(function(data){ }); $http('post',url).success(function(data){ console.log(data); }).error(function(data){ }); }); app.controller("thirdController",function($scope){//controller如果在html中声明了,就要在script中出现 $scope.persons=[ {name:'lifei',age:'30'} ]; }); </script> </html> 

scope rootScope全局作用域

<!DOCTYPE html> <html> <head> <Meta charset="UTF-8"> <script src="angular.min.js"></script> <title></title> </head> <body ng-app="myApp"> <div ng-controller="firstController"> {{name}}{{school}} <div ng-controller="secondController">//secondController继承了firstController可以使用name {{name}}{{age}} </div> </div> </body> <script type="text/javascript"> var app=angular.module("myApp",[]); app.controller("firstController",function($scope){ $scope.name="lifei"; }); app.controller("secondController",$rootScope){//rootScope为全局作用域 $scope.age="25"; $rootScope.school="heda" }); </script> </html> 

$scope代码压缩及app.run方法(初始化全局数据,只对rootScope有用)

<!DOCTYPE html> <html> <head> <Meta charset="UTF-8"> <script src="angular.min.js"></script> <title></title> </head> <body ng-app="myApp"> <div ng-controller="firstController"> {{name}}{{25}} </div> </div> </body> <script type="text/javascript"> var app=angular.module("myApp",['$scope',function($s){ $s.name="lifei"; }]); app.run(["$rootScope",function($rs){//初始化全局数据,只对rootScope有用 $rs.age="25"; }]) </script> </html> 

ap@H_502_1014@ply watch用法

<!DOCTYPE html> <html> <head> <Meta charset="UTF-8"> <script src="angular.min.js"></script> <title></title> </head> <body ng-app="myApp"> <div ng-controller="firstController"> <p><span>单价</span><input type="text" ng-model="phone.price"></p> <p><span>数量</span><input type="text" ng-model="phone.count"></p> <p><span>金额</span>{{sum()|currency:'$'}}</p> <p><span>运费</span>{{phone.fre|currency:'$'}}</p> <p><span>总额</span>{{sum()+phone.fre|currency:'$'}}</p> </div> <div ng-controller="secondController"> <p><span>{{name}} {{age}}</span></p> </div> </body> <script type="text/javascript"> var app=angular.module("myApp",function($s){ $s.phone={ price:5,count:1,fre:10 }; $s.sum=function(){ return $s.phone.price*$s.phone.count; } $s.$watch($s.sum,function(newValue,oldValue){//监控$s.sum $s.phone.fre= newValue>=100?0:10; }); }]); app.controller("secondController",'$timeout',function($s1,$timeout){ $s1.name="lifei" $s1.age="two five"; setTimeout(function(){ $s1.$apply(function(){ $s1.name="李飞" }); },2000); $timeout(function(){ $s1.age="25"; },2000); }]); </script> </html>
