问题 I am able to open Chrome via Selenium, but am unable to simulate a key press (specifically F12, since I want to open Inspect and eventually use the mobile browser Like so) While I'm able to do it manually i.e, open Chrome and press F12, I want to be able to automate this part using Selenium. My current code looks like this - from selenium import webdriver import time from selenium.webdriver.common.action_chains import ActionChains from selenium.webdriver.common.keys import Keys options =

问题 I'm trying to test a feature on my website that produces a random integer. I was wondering if it was possible to use the chrome developer console to trigger a button event with code, without physically pressing the button on the page. Also is it possible to send a different value than what the user put into my textbox. Let's say the user puts his name in "Tom", is there a way to trigger the button event via code in the console as well as change that user input for testing purposes. 回答1: You

问题 I've set up my ASP.NET MVC app with a favicon in the Content folder (instead of the root) along these lines. This works well, the favicon shows in all browsers. However when I installed ELMAH I started seeing 404 errors because apparently the favicon is still being requested at the root of my site! I would love to know why this is happening and who is doing this. Under the assumption my browser was causing this I opened up the developer toolbars, here's what I find: Google Chrome: Internet

问题 I'm currently using Chrome's Developer Tools to create an array which contains every word in the Scrabble dictionary, which I can then use in my Scrabble predictor program. The dictionary can be found here: http://scrabblehelper.googlecode.com/svn-history/r20/trunk/ScrabbleHelper/src/dictionaries/sowpods.txt So far, I've built a jQuery scraper which produces an array of 267,752 words. The code is simply: var allWords = $('pre').innerText; allWords = allWords.split('\n'); I hoped this might

问题 I'm building a front-end in angular that is accessing a flask/python RESTful API. I'm using AngularJS v1.2.16. For some reason, it takes an insane amount of time before the REST resource is loaded, with most of the time just waiting. It's my understanding that 'waiting' is measuring the time to first byte - all my services run locally (the frontend, API and database). Given that the services all run locally, I am at a loss how to debug this. Does anybody have any tips on where to look? I

问题 I am following along with this Udemy course on "Advanced JavaScript", currently reviewing Scopes and watching the video " 9. What is an IIFE and why might you use it?". The instructor is using Chrome DevTools to show JS examples, and created the following three snippets - main.js, other.js, index.html The instructor is trying to show that running main.js will print out: main: Object{hello: "main"} other: Object{hello: "other"} For some reason my index.html file that I'm creating in Chrome

问题 According to PWA Web Bluetooth documentation, it supports "either a BR/EDR or LE connection". I am trying to test using the following code at the console of the Chrome devtools: navigator.bluetooth.requestDevice({ acceptAllDevices: true, }) .then(device => { // Human-readable name of the device. console.log(device.name); console.log(device.id); // Attempts to connect to remote GATT Server. return device.gatt.connect(); }) .then(server => { /* ... */ }) .catch(error => { console.error(error);

问题 Is there a way to give chrome a default width for the devtools window. As it is now, when I start chrome and open DevTools it takes about half the window width. Ideally I would do something like $> /Applications/Google Chrome.app/Contents/MacOS/"Google Chrome" --devtools-width=300 and tell it what the width is. To give a bit of context, I'm running Puppeteer which, in my case, opens DevTools when it starts the browser. But its too wide for me, I need to resize it everytime. Here is my

问题 I'm trying to perform right-click with Puppeteer. I've tried to add the option: await component.click({ button: "right" }) But all I get is a regular click on the component. I followed Puppeteer's API. What am I doing wrong? 回答1: It is correct that you can use elementHandle.click() with the button option set to 'right' to right-click an element: const example = await page.$( '#example' ); await example.click( { button : 'right' }); According to the Official Documentation for elementHandle
