error TS2339: Property ‘timeOrigin’ does not exist on type ‘Performance’

代码如下:

import { WebDriver } from "selenium-webdriver";

export class MyClass {
    public async getTimeOrigin(driver: WebDriver): Promise<number> {
        return await driver.executeScript(function () {
            // This should be the DOM's timeOrigin (same as if a person types "performance.timeOrigin"
            // into the Chrome DevTools console)
            return performance.timeOrigin;
        });
    }
}

报错:

error TS2339: Property ‘timeOrigin’ does not exist on type ‘Performance’

但是它确实存在，因为我可以在Performance对象上查找引用并查看timeOrigin。谁能建议如何解决此问题并正确访问timeOrigin  ?

解决

为避免编译问题，可以将要在浏览器上下文中执行的脚本提供为string（而不是function）：

public async getTimeOrigin(driver: WebDriver): Promise<number> {
    return await driver.executeScript("return performance.timeOrigin;");
}
