How to use AngularJS tools? How to use jQuery in AngularJS?

This article mainly introduces you to the methods of using angularjs tools and the details of using jQuery in angularjs. Let’s take a look at this article together.

1. Angularjs tool method

(1)angular.isArray(value) determines whether it is an array and returns true/false

<p>{{isArray}}</p>

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

(2)angular.isDate(value) determines whether it is a date type and returns true/false

(3)angular.idDefined(value) determines whether it is defined and returns true/false

(4)angular.isElement(node) Determines whether it is a DOM node and returns true/false

(5)angular.isFunction(value) Determines whether it is a Function type and returns true/false

(6)angular.isNumber(value) Determines whether it is Number type, including NaN, Infinity and -Infinity, returns true/false

(7)angular.isObject(value) Determines whether it is Object type, Array is an Object type, Null is not an Object type, returns true/false

(8)angular.isString(value) determines whether it is a string type, returns true/false

( 9)angular.uppercase(value) Convert to uppercase

<p>{{name1}}</p>

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

(10)angular.lowercase(value) Convert to lowercase

(11)angular.equals(o1,o2) Judge two Whether the strings are equal, return true/false

<p>{{eq}}</p>

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

(12)angular.extend(dst,src) Inheritance relationship, as shown in the following code, b inherits the attributes of a

$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) Deserialize the json string and convert the json string into a JavaScript Object

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

(14)angular.toJson(obj,pretty) Format json string

 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]) As shown in the following code, copy a to 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();
