向javascript对象添加方法比向对象构造函数添加方法要容易。我们需要将方法分配给现有属性以确保任务完成。
在下面的示例中，首先创建对象类型，然后再创建对象的属性。创建完属性后，将为每个对象分配一个方法，并根据需要使用该方法访问属性。
<html>
<body>
<p id = "prop"></p>
<script>
function Business(name, property, age, designation) {
this.Name = name;
this.prop = property;
this.age = age;
this.designation = designation;
}
var person1 = new Business("Trump", "$28.05billion", "73", "President");
var person2 = new Business("Jackma", "$35.6 billion", "54", "entrepeneur");
person1.det = function() {
return this.Name + " "+" 拥有净资产 "+ "" + this.prop;
};
person2.det = function() {
return this.Name + " "+" 拥有净资产 "+ "" + this.prop;
};
document.write(person2.det() +" and "+person1.det());
</script>
</body>
</html>Jackma 拥有净资产 $35.6 billion and Trump 拥有净资产 $28.05billion
