问题 I scrapped the page https://www.wikifolio.com/de/de/home for a while now with casperjs. Recently it takes a login to see the information on the page and I just can't get it to work. I can't seem to find which item I have to click to get rid of the disclaimer and later to log into the site. 回答1: It's possible with 2 different ways, this will work: var casper = require('casper').create({ verbose: true, logLevel: 'debug', waitTimeout: 5000, userAgent: 'Mozilla/5.0 (X11; Linux x86_64; rv:49.0)

问题 I use phantomjs to capture a https webpage, but the resulting image is a whole black image. How do I fix it or does it mean phantomjs can't capture an https webpage? code like this: var webpage = require('webpage'); var page = webpage.create(); page.open('https://twitter.com/JavaScriptDaily',function(status){ page.render('twitter.jpeg', {format: 'jpeg', quality: '100'}); phantom.exit(); }); 回答1: Render your image in png, it will solve your problem. var webpage = require('webpage'); var page =

问题 So I have a web page with some photos of people. When you click on a photo of the person the JavaScript is executed and produces a popup with some more detailed information such as a description etc. The link for each photo is as follows: <a href="javascript:void(0)" data="10019" class="seeMore"></a> First I want to start with the basics, of just extracting the description etc. from one single person. So I want to execute the JavaScript above to write the popup window, and when I'm on the

问题 Can anyone suggest me good documentations or steps to start or configure phantomJs driver in java so that i can run my test cases in remote server. 回答1: I run the selenium server in grid mode then connect the phantomjs to it after it is up as it doesn't try to reconnect if it disconnects or isn't fully up ./phantomjs --webdriver=5558 --webdriver-selenium-grid-hub=http://localhost:4444 which will have it listen on port 5558 (for example) but you connect through selenium an it appears as

问题 I've created a jQuery UI Widget that resizes a DIV/thing to fill up the browser screen. It all works fine but now I want to create unit tests for testing that it's resizing and keeping to boundaries etc. I'm using Grunt with grunt-contrib-qunit , which uses PhantomJS to do tests but am now unsure how I can test browser resizing at this point as it's not possible via JS to resize a browser. Perhaps PhantomJS provides something that allows me to alter it at runtime? 回答1: Check CasperJS library.
