Question

我是一个初学者，试图想出这个编码的东西。我无法正确注销。你能发现问题吗？

在字符串中的console.log行中，从$ -sign开始，代码不会改变颜色，因此它不会识别它。谢谢。

const car2 = {
  brand: "Porsche", 
  getCarDescription: function(cost, year, color) {
    console.log("This car is a ${this.brand}.  The price is $${cost}.  The year is ${year}. The color is ${color}.\n");
  }
};

car2.getCarDescription(90000, 2013, "red");

这辆车是$ {this.brand}。价格是$$ {cost}。这一年是$ {year}。颜色是$ {color}。

Answer 1

const car2 = { brand: "Porsche", getCarDescription: function(cost, year, color) 
{ 
console.log(`This car is a ${this.brand}. The price is $${cost}. The year is ${year}. The color is ${color}.\n`); }
 }; 
car2.getCarDescription(90000, 2013, "red");

您需要使用``而不是＆＃34;＆＃34;使用$ {}
