AngularJS 工具方法以及AngularJS中使用jQuery

 1. AngularJS 工具方法，参考angularjs API https://docs.angularjs.org/api官方文档

(1)angular.isArray(value) 判断是否是数组,返回true/false

 

<div ng-controller="firstController">{{isArray}}</div>

$scope.arr=[1,2,3];
$scope.isArray=angular.isArray($scope.arr);

(2)angular.isDate(value) 判断是否是日期类型，返回true/false

(3)angular.idDefined(value) 判断是否被定义了，返回true/false

(4)angular.isElement(node) 判断是否是DOM节点，返回true/false

(5)angular.isFunction(value) 判断是否是Function类型，返回true/false

(6)angular.isNumber(value) 判断是否是Number类型，其中包括NaN,Infinity和-Infinity，返回true/false

(7)angular.isObject(value) 判断是否是Object类型，Array是Objct类型，Null不是Object类型，返回true/false

(8)angular.isString(value) 判断是否是字符串类型，返回true/false

(9)angular.uppercase(value) 转换成大写

<div ng-controller="firstController">{{name1}}</div>

$scope.name='zhangsan';
$scope.name1=angular.uppercase($scope.name);

(10)angular.lowercase(value) 转换成小写

 

(11)angular.equals(o1,o2) 判断两个字符串是否相等，返回true/false

 

<div ng-controller="firstController">{{eq}}</div>

$scope.a='111';
$scope.b='111';
$scope.eq=angular.equals($scope.a,$scope.b);

(12)angular.extend(dst,src) 继承关系，如下代码所示，b继承了a的属性

 

$scope.a={name:'张三'};
$scope.b={age:10};

$scope.c=angular.extend($scope.b,$scope.a);

console.log($scope.b);//{"age":10,"name":"张三"}

(13)angular.fromJson(json) 反序列化json字符串，把json字符串转换成JavaScript Object对象

 

 

var json = '{"name":"hello","age":"20"}';

console.log(json);

$scope.json=angular.fromJson(json);

console.log($scope.json);

 

(14)angular.toJson(obj,pretty) 格式化json字符串

 

var json = {"name":"hello","age":"20"};

// console.log(json);
// $scope.json=angular.toJson(json);

$scope.json=angular.toJson(json,true);

console.log($scope.json);

(15)angular.copy(source, [destination]) 如下代码所示，把a复制给b

 

 

$scope.a={name:'张三'};
$scope.b={age:10};

$scope.c=angular.copy($scope.a,$scope.b);

console.log($scope.a);
console.log($scope.b);

(16)angular.forEach(obj, iterator, [context]) 

 

var json = {"name":"hello","age":"20","sex":'男'};

angular.forEach(json,function(val,key){

      //console.log(val);
    console.log(key);
});

 

var json = {"name":"hello","age":"20","sex":'男'};

var results=[];

angular.forEach(json,function(val,key){
    //console.log(val);
    //console.log(key);
    this.push(key+'--'+val);
},results);

console.log(results);

 

(17)angular.bind(self, fn, args);绑定对象，作为函数的上下文

 

var self={name:'张三'};

var f=angular.bind(self,function(age){

          $scope.info=this.name+' is '+age;

          console.log($scope.info);
});
f(30);

var f=angular.bind(self,function(age){

    $scope.info=this.name+' is '+age;

    console.log($scope.info);
},10);
f();
