Question

我有一个类似的代码库

    //Cart.ts
    import getDataForRequest from '../getData'
    class Cart{
        private user;
        private pwd;
        private env;  // THIS IS THE MEMBER I WANT TO MAKE AVAILABLE TO OTHER PARTS OF THE APP

    constructor(user: string, pwd: string, env: string) {
        this.user = user
        this.pwd = pwd
        this.env = env
    }

    doSomething() {
        getDataForRequest()
    }

   }

// getData.ts
export getDataForRequest() {
    doSomething(env)  // <==  this has to come from that member in Cart
}

我想让该课程的env成员可用于应用程序中的其他模块。因此，当我将类实例化为const foo = new Cart('user123', '12345', 'www.google.com')时，也可以从getData文件访问最后一个参数，而无需在doSomething()中传递参数。

Answer 1

将其作为参数传递。

更改：

doSomething() {
    getDataForRequest()
}

收件人：

doSomething() {
    getDataForRequest(this.env)
}

在Typescript中共享实例化类中的变量
