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();
