Spent forever looking for this, and of course I found the answer minutes after posting the question. I can use the new frame switching commands added to phantomjs in this commit. Specifically, the this.page.switchToChildFrame(0) and this.page.switchToParentFrame() functions. It appears undocumented, and it also seems that the methods have been changed for upcoming releases, but it … Read more
It makes sense, because elmnt.options in the last snippet is an array full with undefined values. So you know the number of elements, but not their values. The reason is that DOM nodes cannot be passed from page context. The docs say: Note: The arguments and the return value to the evaluate function must be … Read more
Probably has to do with the lack of ES6 support in PhantomJS. To check I added page.onError() callback to your script (always handy!) and opened some React example site to get this error: ReferenceError: Can’t find variable: Symbol To polyfill Symbol one can inject a core.js script from this excellent package into the page before … Read more
PhantomJS and SlimerJS (the engines that are used for CasperJS) are not Node.js modules. They can be installed through npm for convenience. They have a different base infrastructure of modules which is distinct from Node.js. You will not be able to use imap or any module that depends on the net module. As Fanch points … Read more
download the PhantomJS binary, upload it somewhere and make it executable (chmod +x) if you are going to make screenshots, setup fontconfig (this is pretty specific to my config but the goal is to make sure to have at least some fonts on your system) run the following in PHP: $response = exec(‘/path/to/phantomjs myscript.js’);
phantomjs-node isn’t an official supported npm package for phantomjs. Instead, it implements a “nauseously clever bridge” between node and phantom by creating a web server that uses websockets to serve as an IPC channel between node and phantom. I’m not making this up: So we communicate with PhantomJS by spinning up an instance of ExpressJS, … Read more
If anyone need in future for the same problem. Using puppeteer-extra I have tested the code on a server. On 2nd run there is google Captcha. You can solve it your self and restart the bot or use a Captcha solving service. I did run the code more than 10 times there is no ip … Read more
As of July 2016, driver.close() and driver.quit() weren’t sufficient for me. That killed the node process but not the phantomjs child process it spawned. Following the discussion on this GitHub issue, the single solution that worked for me was to run: import signal driver.service.process.send_signal(signal.SIGTERM) # kill the specific phantomjs child proc driver.quit() # quit the … Read more
PhantomJS is asynchronous. By calling page.open() multiple times using a loop, you essentially rush the execution of the callback. You’re overwriting the current request before it is finished with a new request which is then again overwritten. You need to execute them one after the other, for example like this: page.open(url, function () { waitFor(function() … Read more
To only render part of a page you need to set the clipRect attribute for the page and then render it. var clipRect = document.querySelector(selector).getBoundingClientRect(); page.clipRect = { top: clipRect.top, left: clipRect.left, width: clipRect.width, height: clipRect.height }; page.render(‘capture.png’); I don’t understand the second part of your question. Phantom.js is headless meaning that there is no … Read more
