How to click on specific part of element puppeteer

问题 Say I have an element that's 500 pixels wide, called 'selector'. How would I go about, for example, clicking on pixel 400? According to the puppeteer docs, .hover() will hover over the middle of the element. And when I tested it using code like const selector = await page.$('selector'); await selector.hover(); await selector.click(); sure enough, it clicked right on pixel 250. So clearly, the code exists to make this happen. I looked through the puppeteer docs, but couldn't find the source

But i get a "schmooze process fail" and the system hangs when it does grover.to_pdf. It works well on terminal but not in my rails project. 回答1: It sounds like your system is hanging because when you run Rails in

Using Puppeteer, how to get Chrome DevTools' “Network” tab's timing information?

由 耗尽温柔 提交于 2020-03-25 04:06:49
问题 Below is a screenshot of me accessing https://www.ted.com and inspecting the Google Chrome DevTools' "Network" tab, and viewing the Timing data for the root & child requests. How can I get all of the above timing data programatically using Puppeteer? Ideally, it would look like this JSON structure: { name: "www.ted.com", queueTime: 0, startedTime: 1.93, stalledTime: 4.59, dnsLookupTime: 10.67, initialConnectionTime: <the number of milliseconds>, ... }, { name: <the next child request>, ... }

Puppeteer Button Press

问题 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"

How to disable core file dumps in docker container

由 ε祈祈猫儿з 提交于 2020-03-18 10:47:09
问题 My PHP container runs puppeteer to generate PDF. By generating a PDF document, it also creates two core dump files inside my container. I am not sure where they actually come from. The host/server is CentOS 7. I've checked following: No application error log, Browsershot/puppeteer is running without errors. No error log (e.g. segfault) found in /var/log/messages I've tried to disable core dumps By following Disable core dumps section of https://linux-audit.com/understand-and-configure-core

Why is puppeteer reporting “UnhandledPromiseRejectionWarning: Error: Navigation failed because browser has disconnected!”?

问题 I've got a simple node.js script to capture screenshots of a few web pages. It appears I'm getting tripped up somewhere along the line with my use of async/await, but I can't figure out where. I'm currently using puppeteer v1.11.0. const puppeteer = require('puppeteer'); //a list of sites to screenshot const papers = { nytimes: "https://www.nytimes.com/", wapo: "https://www.washingtonpost.com/" }; //launch puppeteer, do everything in .then() handler puppeteer.launch({devtools:false}).then
