补全以下遍历对象的代码 var data = { name: "Alex", age: 18, gender:"Male", weight:"70KG" } for (var x in data){ console.log(x+":"+_______) //输出格式: key:value[br][/br] }
举一反三
- 智慧职教: 以下代码运行结果（） var data = { a: 1 } var vm = new Vue({ data: data }) console.log(vm.a === data.a)
- 阅读如下代码,输出结果为“李白”的选项为(__)。 var data = [{"name":"李白","age":5},{"name":"杜甫","age":6}];
- 下列（ ）方法定义和调用的代码是正确的。 A: static void Introduce(string gender = "男", string name, int age = 18){} Introduce(name: "alex", age: 20); B: static void Introduce(string name, int age = 18, string gender = "男"){} Introduce(age: 20, name: "alex"); C: static void Introduce(string gender = "男", string name, int ago = 18){} Introduce(age: 20, name: "alex"); D: static void Introduce(string name, int age = 18, string gender = "男"){}Introduce(name: "alex", age: 20);
- 下列代码输出的结果是 var y = 1; var x = y = typeof x; console.log(x); A: undefined B: 1 C: y D: 报错
- 在javascript中，执行后输出的结果是： var name="zhaonan"; var obj1={ name:"miao", age:20, say:function(){ console.log(this.name); } } var obj2={ name:"xue", age:30, say:function(){ console.log(this.name); } } var f=obj2.say; console.log(f()); var e=f.bind(obj1); console.log(e()); var k=e.bind(obj2); console.log(k()); A: zhaonan zhaonan miao B: zhaonan miao miao C: zhaonan miao xue D: miao zhaonan xue
