Using internal puppeteer page._client methods we can make use of Chrome DevTools Protocol directly: (async() => { const browser = await puppeteer.launch({}); const page = await browser.newPage(); await page

Puppeteer: How to submit a form?

由 人盡茶涼 提交于 2020-01-01 01:58:10
问题 Using puppeteer, how could you programmatically submit a form? So far I've been able to do this using page.click('.input[type="submit"]') if the form actually includes a submit input. But for forms that don't include a submit input, focusing on the form text input element and using page.press('Enter') doesn't seem to actually cause the form to submit: const puppeteer = require('puppeteer'); (async() => { const browser = await puppeteer.launch(); const page = await browser.newPage(); await

问题 I'm trying to follow the instructions here to bundle puppeteer, with the intention of including it in a chrome extension as a hacky way of scripting operations in the browser window (specifically, printing a page to PDF, which is surprisingly impossible with just the Chrome Extension API as far as I can tell). As per the README in the link above, I've set up my Chrome extension as follows: background.html <script src="./puppeteer/utils/browser/puppeteer-web.js"></script> <script src=

问题 I'm trying to inject jquery into my puppeteer page because document.querySelector doesn't cut it for me: async function inject_jquery(page){ await page.evaluate(() => { var jq = document.createElement("script") jq.src = "https://code.jquery.com/jquery-3.2.1.min.js" document.querySelector("head").appendChild(jq) }) const watchDog = page.waitForFunction('window.jQuery !== undefined'); await watchDog; } The result is it mostly times out. Does anyone have a solution? 回答1: I have used page

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 核心优势 异构服务：支持多种运行环境 用于媒体文件转换的库或者二进制往往和业务的运行环境不同，对计算资源的需求也有较大的差异。 函数计算支持多种运行环境，支持为独立的转换函数定制算力单位，根据请求量自动伸缩，让核心业务和支持业务做到较好的分离。 灵活触发：支持多种触发方式 函数计算既可以通过集成事件源服务（OSS、API 网关、日志服务和表格存储）产生事件来触发函数执行，也可以通过 HTTP 触发器使用 HTTP 请求触发函数执行，还支持 API/SDK 直接调用函数。 弹性伸缩: 轻松应对负载的波峰波谷 函数计算提供跨可用区的容灾能力，根据请求量自动进行毫秒级弹性扩容，快速调度计算资源，轻松应对业务洪峰。 预留实例功能彻底消除实例冷启动带来的延时毛刺，为在线应用迁移至函数计算扫清障碍! 工程效率：搭建速度快，运维代价小 使用函数计算，开发者无需管理服务器等基础设施，只需编写并上传代码，函数计算准备好计算资源，弹性可靠地运行任务，并提供完备的日志与监控报警服务，帮助服务快速上线且免除繁琐的运维操作。 最佳实践 快速开发一个分布式 Puppeteer 网页截图服务 示例搭建了一个具备弹性的 Puppeteer 网页截图服务，实现的功能为：客户端将想要截图的网页地址发送给函数，函数负责渲染网页内容，并截图返回。

Page Object Model structure for a complex application

由 允我心安 提交于 2019-12-25 01:48:25
问题 I've in the past couple of months used Puppeteer to drive an automation for a couple of small level projects. Now I want to scale the framework for a medium/large complex application. I want to use the famed Page Object Model, where in I have separated the locators, page methods in separate files and I'm calling them in the corresponding page execution code. My directory structure is like this e2e_tests - locators - common-locators.js - page1locators.js - page2locators.js - constants - config
