JavaScript string interpolation on strings assigned as property values in objects

Question

I have the following object:

var obj = {
   number: "123456789"
   tel: `The clients phone number is ${number}. Please call him!`

How can I insert the number value in the tel-string?

Answer 1

初始化时无法访问该对象。您可以在对象初始化之后分配属性，也可以定义getter属性：

const obj = {
  number: "123456789",
  get tel() {
    return `The clients phone number is ${this.number}. Please call him!`;
  }
};

console.log(obj.tel);
