本篇文章主要的向大家介紹了關於angularjs的工具使用的方法和angularjs中使用jQuery的詳情,我們一起來看看這篇文章吧。
1. Angularjs 工具方法
#(1)angular.isArray(value) 判斷是否為陣列,回傳true/false
<p>{{isArray}}</p>
$scope.arr=[1,2,3]; $scope.isArray=angular.isArray($scope.arr);
(2)angular.isDate(value) 判斷是否為日期類型,回傳true/false
(3)angular.idDefined(value) 判斷是否被定義了,回傳true/false
(4)angular.isElement(node) 判斷是否為DOM節點,回傳true/false
(5)angular.isFunction(value) 判斷是否為Function類型,回傳true/false
(6)angular.isNumber(value) 判斷是否為Number類型,其中包含NaN,Infinity和-Infinity,傳回true/false
(7)angular.isObject(value) 判斷是否是Object類型,Array是Objct類型,Null不是Object類型,回傳true/false
(8)angular.isString(value) 判斷是否為字串類型,回傳true/false
( 9)angular.uppercase(value) 轉換成大寫
<p>{{name1}}</p>
$scope.name='zhangsan'; $scope.name1=angular.uppercase($scope.name);
(10)angular.lowercase(value) 轉換成小寫
(11)angular.equals(o1,o2) 判斷兩個字串是否相等,傳回true/false
<p>{{eq}}</p>
$scope.a='111'; $scope.b='111'; $scope.eq=angular.equals($scope.a,$scope.b);
(12)angular.extend(dst,src) 繼承關係,如下程式碼所示,b繼承了a的屬性
$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字串,把json字串轉換成JavaScript Object物件
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]) 如下程式碼所示,把a複製給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();
