Javascript 木偶刮削台

我有下面的脚本与木偶正确地工作，这段代码提取所有有关表的信息

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  const tableRows = await page.$$('table > tbody tr');

    await page.goto("https://www.mismarcadores.com/baloncesto/espana/liga-endesa/partidos/");

    const time = await page.evaluate(() => {

        const tables = Array.from(document.querySelectorAll('table tr .time'));
        return tables.map(table => table.textContent)
     });

    const teamHome = await page.evaluate(() => {
        const tables = Array.from(document.querySelectorAll('table tr .team-home'));
        return tables.map(table => table.textContent)
     });

     const teamAway = await page.evaluate(() => {
        const tables = Array.from(document.querySelectorAll('table tr .team-away'));
        return tables.map(table => table.textContent)
     });


     for (let i = 0; i < time.length; i++) {
        console.log(time[i]);
        console.log(teamHome[i]);
        console.log(teamAway[i]);
     }  

  await browser.close();
})();

当我尝试执行第二个脚本时，我收到了未定义的脚本

结果将是将第一个脚本传递给第二个脚本

有人能帮我吗？

您需要指定更多的

tr

元素（比如添加

.stage scheduled

类），并返回

.textContent

属性，而不是元素本身。试试这个：

var data=wait page.evaluate（（）=>{
返回数组.from(
document.querySelectorAll（'table tr.stage-scheduled'）
).map（行=>{
返回{
时间：row.querySelector（“.time”）.textContent，
teamHome:row.querySelector（“.teamHome”）.textContent，
teamAway:row.querySelector（“.teamAway”）.textContent，
};
});
});

您在

数组前面缺少了
return
。从
中。Thank正在工作，但现在我无法提取信息
(async () => {
  const browser = await puppeteer.launch({ headless: false });
  const page = await browser.newPage();
    await page.goto("https://www.mismarcadores.com/baloncesto/espana/liga-endesa/partidos/");
    console.log("started evalating");
    var data = await page.evaluate(() => {
      Array.from(
        document.querySelectorAll('table tr')
      ).map(row => {
        return {
          time: row.querySelector(".time"),
          teamHome: row.querySelector(".team-home"),
          teamAway: row.querySelector(".team-away")
        };
      });
    });
  console.log(data);
})();
