Javascript - 将对象的值转换为大写

Question

我的 Angular.io 或 IONIC 中有一个对象

{name:"food panda", city:"selangor", phone:"0123456789"}

并使用以下代码，但它不起作用:

this.restaurant.name.toUpperCase();

我需要将 food panda 转换为 FOOD PANDA。

我该怎么做？

Answer 1

toUpperCase returns a new String, it doesn't modify the original

var restaurant = { name: "food panda", city: "selangor", phone: "0123456789" };

restaurant.name.toUpperCase();

console.log(restaurant.name);           // output: food panda

var restaurantName = restaurant.name.toUpperCase();

console.log(restaurantName);            // output: FOOD PANDA
