Используя Puppeteer, как я могу открыть страницу, получить данные и перейти на предыдущую страницу с этими данными в цикле

Question

Используя Puppeteer, я хотел бы получить все элементы на странице с определенным именем класса, а затем l oop и щелкнуть по каждому из них и go вернуться на другую страницу, нажав на эти данные со страницы.

Я пробовал это:

await page.goto('https://myschool.ng/classroom/christian-religious-knowledge-crk?exam_type=jamb&exam_year=2019', {waitUntil: 'load', timeout: 100000})
  let  questions=  await page.$$('div.media-body') 
  let data = [] 
  await questions.forEach(async (element, i)=>{
         let question =  await  element.$eval(".question-desc.mt-0.mb-3 > p", el=>el.innerHTML)
         let options =   await element.$$eval("ul >li",el=>el.map(option=>option.innerHTML))
          await page.waitFor(2000)

          await element.$eval('a', el=>el.click())
          await page.waitForSelector("h5.text-success.mb-3")
          let correctOption = await page.$eval('h5.text-success.mb-3', el=>el.innerHTML)
          //data.push({question, options, correctOption})
          page.goBack()
          console.log({question, options, correctOption}, i)
    })

, но я всегда получаю это в своем журнале консоли:

Я пробовал все, но правильный вариант не данные, которые я перебираю в сети и показывающие первый вариант.

Answer 1

Основная причина была в том, что forEach работает асинхронно, и мне нужен l oop для синхронной работы. Окончательное решение -

await page.goto('https://myschool.ng/classroom/christian-religious-knowledge-crk?exam_type=jamb&exam_year=2019', {waitUntil: 'load', timeout: 100000})
  let  questions=  await page.$$('div.media-body') 
  let data = [] 
    for (let index = 0; index < questions.length; index++) {
        let question =  await questions[index].$eval(".question-desc.mt-0.mb-3 > p", el=>el.innerHTML)
        let options =   await questions[index].$$eval("ul >li",el=>el.map(option=>option.innerHTML))
        await questions[index].$eval('.btn', el=>el.click())
        await page.waitFor(2000)
        await page.waitForSelector("h5.text-success.mb-3")
         .then( async()=>{
            console.log(await  page.$eval(" .text-success.mb-3", el=>el.innerHTML))
            page.goBack()
            await page.waitFor(2000)
            questions=  await page.$$('div.media-body') 
         })
         .catch(async ()=>{
            console.log("jsjjs")
             page.goBack()
             await page.waitFor(2000)
           questions=  await page.$$('div.media-body') 
         })
    }

})
