我正在努力為登錄功能添加額外的檢查。如果傳遞給函數(shù)的對(duì)象包含屬性名稱(chēng)additionalSteps，它將調(diào)用additionalSteps 屬性。但是，每當(dāng)我到達(dá)調(diào)用步驟時(shí)，都會(huì)收到一條錯(cuò)誤消息，指出該屬性不是函數(shù)或未定義。options.additionalSteps（取決于我如何通過(guò)調(diào)用對(duì)象 property( ) 或?qū)⒕植孔兞糠峙浣o對(duì)象 property( )來(lái)調(diào)整代碼let additionalSteps。）我想知道是否可以傳遞一個(gè)具有定義函數(shù)/方法的屬性的對(duì)象，然后將該對(duì)象傳遞到導(dǎo)入類(lèi)（或使用）的函數(shù)中，該函數(shù)將檢查屬性名稱(chēng)是否存在，然后調(diào)用該對(duì)象的require函數(shù)如果條件為真。我可以讓其他文件定義并處理該函數(shù)，但我希望用戶(hù)按照他們的意愿定義屬性函數(shù)。根據(jù)我對(duì)該主題的研究，我對(duì)屬性的感覺(jué)是不可能通過(guò)對(duì)象內(nèi)的另一個(gè)文件傳遞函數(shù)/方法。（有關(guān)具有函數(shù)的對(duì)象屬性的所有信息和示例似乎暗示這不受支持。）測(cè)試代碼：async function fewMoreSteps({page, options} = {}) {  console.log('This is the addtional step...')  await page.waitForSelector('#header_notification_link', {visible: true})  await page.click('#header_notification_link')}describe('Test Login', () => {  // eslint-disable-next-line jest/no-focused-tests  it.only('Login with custom function', () => {    const username = Cypress.env('steamUserName')    const password = Cypress.env('steamUserNamePW')    const loginUrl = Cypress.env('loginUrl')    const loginSelector = Cypress.env('loginSelector')    const cookieName = Cypress.env('cookieName')    const socialLoginOptions = {      username,      password,      loginUrl,      // Add username/pw fields and buttons and addtional steps      usernameField: '#input_username',      passwordField: '#input_password',      passwordSubmitBtn: '#login_btn_signin',      // make this a global passed function      additionalSteps: async function({page, options} = {}) {        /*console.log('This is the addtional step...')        await page.waitForSelector('#header_notification_link', {visible: true})        await page.click('#header_notification_link') */         await fewMoreSteps({page, options})      },      isPopup: true,      popupDelay: 6000,      logs: true,      headless: false,      loginSelector: loginSelector,      postLoginClick: '#account_pulldown',      postLoginSelector: '#account_dropdown div.popup_menu a.popup_menu_item:first-of-type'    }
