1.使用Object或对象字面量创建对象 // 生成一个对象varstudent=newObject();// 封装两个属性student.name='easy'; student.age='20'; 2.工厂模式创建对象 // 工厂模式functioncreateStudent(name,age){// 实例化一个对象varobj=newObject();//给这个对象封装属性obj.name=name; obj.age=age;//将这个对象...
The edge cases are a bit different, though—the Object.getOwnPropertyNames() method will still return true for a Date, but will return false for a RegExp. 1 console.log(isEmptyObject(Date.now())); //output: true 2 console.log(isEmptyObject(new RegExp()); //output: false Once aga...

提供五种基本的引用类型:Object, Array, Function, Date 及RegExp。数组,函数,日期和正则表达式是特殊类型,但是严格来讲,日期和正则表达式是元数据类型,可封装在其他对象中。 JS 中变量类型,数组元素类型,函数参数以及返回值的类型不需要声明类型,类型之间的转换是自动执行的。
Date.parse将返回一个时间戳(以毫秒为单位)而不是Date对象。 您还可以传递一组代表日期各部分的有序值:年,月(从0开始),日,小时,分钟,秒和毫秒: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 newDate(2018,6,22,7,22,13,0)newDate(2018,6,22) ...
