TS2339：类型“窗口”上不存在属性“ *”。仅在WebStorm中

Question

Win 10 Pro 64位

WebStorm：2018.2.3

错误：

在我的interfaces.ts文件中：

declare global {
  interface Window {
    dataLayer?: Array<any>;
    gtag?: (...args) => void;
    ga?: (action: string, type: string, data: Object) => void;
  }
}

Answer 1

您可以执行以下操作：

const eventName = 'event';
const handlerName= doAction;
const target = ( <any>window ); // <===== THIS IS THE WORK AROUND

target.ga && target.ga(eventName, handlerName)
