JSON 在 Typescript 应用程序中找不到
JSON not found in Typescript application
我有一个简单的购买 class:
export class Purchase {
customer!: Customer;
shippingAddress!: Address;
billingAddress!: Address;
order!: Order;
orderItems!: OrderItem[];
}
我有一个执行以下操作的结帐组件:
// populate purchase - customer
purchase.customer = this.checkoutFormGroup.controls['customer'].value;
// populate purchase - shipping address
purchase.shippingAddress = this.checkoutFormGroup.controls['shippingAddress'].value;
const shippingState: State = JSON.parse(JSON.stringify(purchase.shippingAddress.state));
const shippingCountry: Country = JSON.parse(JSON.stringify(purchase.shippingAddress.country));
purchase.shippingAddress.state = shippingState.name;
purchase.shippingAddress.country = shippingCountry.name;
下面几行给出了错误 Cannot find name 'JSON'.ts(2304)
:
const shippingState: State = JSON.parse(JSON.stringify(purchase.shippingAddress.state));
const shippingCountry: Country = JSON.parse(JSON.stringify(purchase.shippingAddress.country));
我怀疑问题是我在 tsconfig.json
中有以下配置:
"compilerOptions": {
...
"target": "es2017",
"module": "es2020",
"lib": [
"es2018",
"dom"
]
}
我尝试将 es2018
更改为 es5
但这并没有解决我的问题。无论哪种方式,肯定应该有一种方法可以用 es2018
做这种事情。谁能告诉我如何解决这个问题?
This 帮我解决了问题。版本是 4.5.something。现在是 4.2.2,现在找到 JSON。
