对象object
例子一:
var car = {
"wheels":4, "engines":1, "seats":5};例子二:
var Car = function() {
this.wheels = 4; this.engines = 1; this.seats = 1;};//构造函数调用构造函数
var Car = function() { this.wheels = 4;this.engines = 1;this.seats = 1;};
var myCar=new Car();
myCar.nickname="aaaa";
注意:当 myCar
(即 Car
的一个 实例 )创建后,他可以像普通对象一样被使用,包括创建、访问、修改它的属性等,就像我们使用其他对象一样。
向构造函数中添加参数
var Car = function(wheels,seats,engines) {
//Change this constructor this.wheels =wheels; this.seats = seats; this.engines = engines;};
