javascript - 构造函数及其变量

Question

我试图通过一个名为 this.anh< 的变量将 age、name 和 height 一起调用 来自名为 person 的函数。我写列表的方式是错误的，但正确的表示法是什么？如果有多种方式，请写下来。 :)

<script type="text/javascript">

function person(age, name, height){
this.age = age;
this.name = name;
this.height = height;
this.anh = age, name, height;
}

var koolz = new person(20,"koolz",200);



document.write(koolz.anh)

</script>

您需要在需要的地方添加文字并连接动态值。

function person(age, name, height){
   this.age = age;
   this.name = name;
   this.height = height;

   // If you want a literal comma and space to separate the values
   // then you need to concatenate them to the variables.
   this.anh = age + ", " +  name + ", " + height;

   // Or, if the data were in an array, like this:
   var arry = [this.age, this.name, this.height ];
   
   // You could concatenate them like this:
   var result = arry.join(", ");
   console.log(result);
}

var koolz = new person(20,"koolz",200);
document.write(koolz.anh)
