Anglarjs 工具方法

Angularjs 常用方法

1. isArray使用

效果图如下，结果为true

2.uppercase使用

$scope.name = "zhangsan";

$scope.name = angular.uppercase( $scope.name );

htmle中
zhangsan 转为大写 {{name}}

结果为:zhangsan 转为大写 ZHANGSAN

3. toJson方法

将json转为字符串

var  json = {"name":"hello", "age":"20"};
var jsonstr = angular.toJson(json);
console.log(jsonstr);

打印结果
{"name":"hello","age":"20"}

4. formJson方法
将string转为json

var jsonstr = '{"name":"hello", "age":"20"}';
var json = angular.fromJson(jsonstr);
console.log(json);

打印效果

5. forEach使用

var json = {"name":"hello", "age":"20"};
angular.forEach(json,function(val, key){
console.log(key + " : " + val);
});

效果：

加入第三个参数results

var json = {"name":"hello", "age":"20"};
var results=[];
angular.forEach(json,function(val, key){
this.push(key + " : " + val);
}, results);

console.log(results);

7. 模块依赖

<!DOCTYPE html>

<html>

<head>

    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

    <title>无标题文档</title>

    <script type="text/javascript" src="angular.min.js"></script>

    <script type="text/javascript" src="module02.js"></script>

</head>

<body ng-app="myApp">

<div>

    <div ng-controller="firstController">

       {{name}}

    </div>

    <div ng-controller="secondController">

        {{name}}

    </div>

    <div ng-controller="thirdController">

        {{name}}

    </div>

</div>

<script type="text/javascript">

    var app = angular.module("myApp", ['myApp2']);

    app.controller('firstController',['$scope',function($scope){

        $scope.name = "张三";

    }]);

</script>

</body>

</html>

module02.jｓ文件

var app2 = angular.module("myApp2", []);

app2.controller('secondController',function($scope){

    $scope.name='李四';

});

app2.controller('thirdController',function($scope){

    $scope.name='王五';

});

8. Jquery的使用

<!DOCTYPE html>

<html>

<head>

    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

    <title>无标题文档</title>

    <script type="text/javascript" src="jquery-1.11.1.js"></script>

    <script type="text/javascript" src="angular.min.js"></script>

    <script type="text/javascript" src="module02.js"></script>

</head>

<body ng-app="myApp">

<div>

    <div ng-controller="firstController">

        <div id="main"></div>

       {{name}}

    </div>

    <div ng-controller="secondController">

        {{name}}

    </div>

    <div ng-controller="thirdController">

        {{name}}

    </div>

</div>

<script type="text/javascript">

    var app = angular.module("myApp", ['myApp2']);

    app.controller('firstController',['$scope',function($scope){

        $scope.name = "张三";

        $('#main').html('<span>hello world</span>');
