The examples in this article summarize the object-oriented implementation method of JavaScript. Share it with everyone for your reference. The specific analysis is as follows:
Method 1:
var person = {
name: 'hello world',
age: 22,
sayHello:function(){
alert('I\'m 'this.name ',and I\'m ' this.age 'years old');
}
};
person.sayHello();//I'm hello world, and I'm 22 years oldMethod 2:
window.color = "red";
var o = { color: "blue"};
function sayColor(){
alert(this.color);
}
sayColor(); //"red"
o.sayColor = sayColor;
o.sayColor(); //"blue"
//也可以使用apply和call
sayColor.apply(o);//"blue"
sayColor.call(o);//"blue"I hope this article will be helpful to everyone’s JavaScript programming design.
