selenium

问题 What I need is to add a script tag to the head of html document. I am using the code below but when I view page source, the script is not there. Thank you in advance, driver = webdriver.Chrome() driver.get("http://www.x.org") execu = ''' var scr = document.createElement('script'); scr.type = 'text/javascript'; scr.text = `let calls = (function(){ let calls = 0; let fun = document.createElement; document.createElement = function(){ calls++; return fun.apply(document, arguments); } return ()=

问题 From within Java unit tests, I want to use Selenium to test my web page with Firefox. My tests require that I set an environment variable for Firefox. (Specifically, I want to set the DISPLAY variable.) The FirefoxBinary class has a method setEnvironmentProperty, which sounds like it should set environment variables for the environment the Firefox process runs in, but in practice it does not have that effect. (I have confirmed that with cat /proc/<firefox_pid>/environ .) Back with selenium

问题 I have been trying to scrape all the reviews available at a single url by repeatedly clicking on the button 'Show 6 more reviews' . I believe this problem would apply to anyone scrapping many dynamic elements at a single url with Selenium. Problem: when the number of reviews is more than a few hundreds, the loop becomes very slow. I am using Selenium since the website involves Javascript. HTML of button I am clicking (towards bottom of page) <button type="button" class="css-1e0935c" data-comp

问题 I'm trying to scrape some urls with Scrapy and Selenium. Some of the urls are processed by Scrapy directly and the others are handled with Selenium first. The problem is: while Selenium is handling a url, Scrapy is not processing the others in parallel. It waits for the webdriver to finish its work. I have tried to run multiple spiders with different init parameters in separate processes (using multiprocessing pool), but I got twisted.internet.error.ReactorNotRestartable . I also tried to
