表单提交后 Puppeteer 等待页面加载 [英] Puppeteer wait page load after form submit

问题描述

我使用以下代码提交表单，我希望 Puppeteer 在表单提交后等待页面加载.

I submit a form using the following code and i want Puppeteer to wait page load after form submit.

await page.click("button[type=submit]");

//how to wait until the new page loads before taking screenshot?
// i don't want this:
// await page.waitFor(1*1000);  //← unwanted workaround
await page.screenshot({path: 'example.png'});

推荐答案

您可以异步等待导航以避免在重定向时获得 null，

You can wait for navigation asynchronously to avoid getting null on redirection,

await Promise.all([
      page.click("button[type=submit]"),
      page.waitForNavigation({ waitUntil: 'networkidle0' }),
]);

如果 page.click 已触发导航，这将对您有所帮助.

This will help you if the page.click already triggers a navigation.
