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();

我需要转换food panda为FOOD PANDA.

我怎样才能做到这一点？

Answer 1

toUpperCase返回一个新的String,它不会修改原始的

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
