AngularJS入门-demo

双向绑定测试：

<body ng-app>

    请输入姓名：<input ng-model="myname">

    <br>

    {{myname}},你好

</body>

这时候AngularJS会自动绑定对象myname，并且在下放的{{myname}}中显示出来

初始化指令：

　　通过ng-init来初始化对象，使对象有默认的数值：

<body ng-app   ng-init="myname='陈大海'">

　　请输入你的姓名：<input ng-model="myname">

　　<br>

　　{{myname}},你好

</body>

此时默认显示出来的内容：

陈大海，你好

控制器：

<script >
　　　　　　//定义一个对象函数

        var app =angular.module('myApp',[]);
　　　　　　//定义对象的controller，叫做myController，后方就是controller的内容

        app.controller('myController',function($scope){

            $scope.add=function(){

                return parseInt($scope.x)+parseInt($scope.y)

            }

        });

    </script>

调用

<body ng-app="myApp" ng-controller="myController">

    x:<input ng-model="x" >

    y:<input ng-model="y" >

        运算结果：{{add()}}

</body>

也可以用$scope.x=10，设定x默认值为10

事件指令：

<head>

    <title>

        demo

    </title>

    <script src="angular.min.js"></script>

    <script >

        var app =angular.module('myApp',[]);

        app.controller('myController',function($scope){

            $scope.x=10;

            $scope.add=function(){

                $scope.z=parseInt($scope.x)+parseInt($scope.y);

            }

        });

    </script>

</head>

<body ng-app="myApp" ng-controller="myController">

    x:<input ng-model="x" >

    y:<input ng-model="y" >

    <button ng-click="add()">运算</button>

        运算结果：{{z}}

</body>

创建$scope.z对象和函数，但是并不主动调用函数，当按下ng-click的时候，进行add()的调用，然后主动回显结果

循环：

<script src="https://cdn.staticfile.org/angular.js/1.4.6/angular.min.js"></script>

<script>

var app = angular.module("myApp", []);

app.controller("myController", function($scope) {

  $scope.list = [10,20,30,40]

    });

</script>

</head>

<body ng-app="myApp" ng-controller="myController">

    <table>

        <tr ng-repeat="x in list">

            <td>{{x}}</td>

        </tr>

    </table>

</body

先用$scope创建一个list

在用ng-repeat命令调用该list

循环数组：

app.controller("myController", function($scope) {

    $scope.list= [

        {name:'张三',shuxue:100,yuwen:93},

        {name:'李四',shuxue:88,yuwen:87},

        {name:'王五',shuxue:77,yuwen:56}

    ];

    });

</script>

</head>

<body ng-app="myApp" ng-controller="myController">

    <table>

        <tr>

            <td>姓名</td>

            <td>数学</td>

            <td>语文</td>

        </tr>

        <tr ng-repeat="entity in list">

            <td>{{entity.name}}</td>

            <td>{{entity.shuxue}}</td>

            <td>{{entity.yuwen}}</td>

        </tr>

    </table>

类似类的调用。

内置服务：$http

<script>

    var app = angular.module("myApp",[]);

    app.controller("myController",function($scope,$http){

        $scope.findAll=function(){

            $http.get("data.json").success(

                function(response){

                    $scope.list=response;

                }

            );

        }

    });

</script>

</head>

<body ng-app="myApp" ng-controller="myController" ng-init="findAll()">

    <table>

        <tr>

            <td>姓名</td>

            <td>数学</td>

            <td>语文</td>

        </tr>

        <tr ng-repeat="entity in list">

            <td>{{entity.name}}</td>

            <td>{{entity.shuxue}}</td>

            <td>{{entity.yuwen}}</td>

        </tr>

    </table>

data.json

[

    {"name":"张三","shuxue":100,"yuwen":93},

    {"name":"李四","shuxue":88,"yuwen":87},

    {"name":"王五","shuxue":77,"yuwen":56},

    {"name":"赵六","shuxue":67,"yuwen":86}

]

要注意<body ng-init="findAll()"> 要初始化angularJS的函数，即$scope.findAll(),不然http会注入失败。
