phantomjs

问题 It seems that every time I update my OS, R, or any browsers Rselenium stops working. I can no longer use it with any browser -Firefox, Chrome, or PhantomJS. I've posted my code below.

问题 I'm using the RSelenium library with the argument browserName = "phantomjs" in the remoteDriver command, however I was looking to run a test where I specify the type of the proxy server. I've seen that proxy authentication is possible in, e.g. Java, with the code used shown here: ArrayList<String> cliArgsCap = new ArrayList<String>(); cliArgsCap.add("--proxy=address:port"); cliArgsCap.add("--proxy-auth=username:password"); cliArgsCap.add("--proxy-type=http"); DesiredCapabilities capabilities

I added the PhantomJS driver dependency as follows with other dependencies in pom.xml: <dependency> <groupId>com.github.detro</groupId> <artifactId>phantomjsdriver</artifactId> <version>1.2.0</version> </dependency> But it is getting error: java.lang.NoClassDefFoundError: org/openqa/selenium/io/CircularOutputStream at org.openqa.selenium.firefox.FirefoxBinary.<init>

问题 I'm learning PhantomJS and wondered if it's possible to use jQuery DOM selectors in the JS files PhantomJS runs? I've seen a short example on github that appears to indicate this: Sample of PhantomJS with Qunit (and jQuery?) If you look at the run-qunit.js file at the top it seems state you can use jQuery DOM selectors as parameters. But I'm getting errors when I do that-- not sure whether it's my syntax or because Phantom doesn't know about jQuery, so I thought I'd ask first about the

问题 I'm trying to get a full sized browser screenshot with phantomjs driven by python webdriver . right now my screenshot is measured at 927 x 870, I'd like to reset it. I have tried: driver.manage().window().setSize(new Dimension(1400,1000)) based on this source, but this is giving syntax errors. How can I do this? 回答1: Because that's Java. Python's documentation is here. There's a method called set_window_size , which is defined here: driver.set_window_size(1400,1000) Further reading: How to

问题 I have a casperjs script which gives the desired result when I run on a linux server, but when I run the same from my laptop, it doesn't work. How should I debug? Logs of the working one: [info] [phantom] Starting...

问题 I am loosing my mind over trying to do something inherently seemingly banal, but it seems almost hopeless. For a thesis project I need to collect flight prices. This code should just fill in "zurich" to the departure box. But it doesn't. This code works normally with any text imput box, but on this simple page its hopeless. I really would appreciate someones wisdom here: // variables var casper = require("casper").create(); var x = require('casper').selectXPath; var url = 'http://www

问题 I am running Phantom on a Node server, in order to generate pages from data and then render it as pdf. However, while the pages work and are correctly rendered as pdf and everything, I cannot get them to take into account an external CSS file. Here is a simplified version of what I am trying to do: var phantom = require ('phantom'); phantom.create(function (ph) { ph.createPage(function (page) { var content = ""; content += '<html><head>'; content += '<link rel="stylesheet" href="/temp.css">';
