According to https://github.com/GoogleChrome/puppeteer/blob/master/docs/api.md#pagepresskey-options, you can simulate the pressing of a keyboard button with Puppeteer.
Here’s what I do:
// First, click the search button
await page.click('#outer-container > nav > span.right > span.search-notification-wrapper > span > form > input[type="text"]');
// Focus on the input field
await page.focus('#outer-container > nav > span.right > span.search-notification-wrapper > span > form > input[type="text"]');
// Enter some text into the input field
await page.type("Bla Bla");
// Press Enter to search -> this doesn't work!
await page.press("Enter");
The pressing of the button doesn't produce anything. It's basically ignored.
How can I simulate the Enter key to submit the form?
