phantomjs

问题 I am attempting to run my casperjs script by clicking a Run button in a website. My local set up is PHP 5.5.14 with Apache 2.4 on Windows7 [properly running; tested with php page]; and my question is: how do I properly install casperJS and phantomJS so that its PATH is recognized when I execute the script. I need to know what the path is in Windows to be able to use this: putenv("PHANTOMJS_EXECUTABLE=/usr/local/bin/phantomjs"); . I have gone over the following possible solutions but none of

问题 I have a NodeJS app using PhantomJS to generate PDF files. My app is deployed to Heroku and I'm using this phantom build pack. Unfortunately this build pack does not support the page-break-inside: avoid CSS property. I did a research and found 2 hacks on this GitHub issue page. I've tried both of them, but unfortunately I can't use the CSS one, due to my page structure and the JavaScript one isn't page-breaking properly. One of the guys in the GitHub link above mentioned that this problem is

问题 Am using PhantomJS and CasperJS for screenscraping and stuff. The issue which I am facing is that its taking too much CPU usage which makes me feel it might not be that scalable. Are there any ways to reduce CPU usage for the same. Some of which I can think of are: 1) Disable image loading 2) Disable js loading Also I want to know if python is more light(in terms of CPU usage) than phantom for the scraping purpose. 回答1: After 5 and a half years I don't think you are having this issue anymore,

问题 The error is: Select only works on <select> elements, not on <span>. Trying to accomplish this using PhantomJS & Selenium in Python.

问题 I am getting the following error: "Error in checkError(res) : Couldnt connect to host on http://localhost:4444/wd/hub. Please ensure a Selenium server is running."

问题 I am trying to run CasperJS on a javascript file that I have, and when I run > casperjs index.js it says 'CasperError: Cant find module fs'. The first line of index.js is var fs = require('fs'); I have node, casperjs, and phantomjs installed, why can't it find fs? If I am correct, fs is Node's file system? UPDATE: I added nodejs to my $PATH, but still no luck. 回答1: Did you install the PhantomJS/CasperJS modules as well as the node fs module in your project? They don't seem to mix very well. I

问题 I need to run Karma tests using PhantomJS on a continuous integration server with no internet access. Every build starts from running npm install --no-registry and then grunt Grunt Karma is configured for single run ( singleRun: true ) Everything works well except PhantomJS. Even though phantomjs package is in npm-cache it tries to download actual binary (.exe in my case) directly from bitbucket.org and obviously fails due to no inet access. I tried to pre-install PhantomJS package globally (

问题 Is there a programmatic (since i want to do it automatically at runtime) way to see how much memory a webpage uses when running it through PhantomJs? I am also using casperjs if that could be helpful. I have searched a lot but haven't found any way. PhantomJs uses QtWebKit so I don't have access to window.performance.memory. I want to have this information since I am setting up automated performance tests for a web application. Thanks in advance 回答1: No, at this time this feature is not
