Get javascript rendered html source using phantomjs

Question

First of all, I am not looking for any help in development or testing environment. Also I am new to phantomjs and all I want is just the command line operation of phantomjs

Answer 1

Unfortunately, that is not possible using just the PhantomJS command line. You have to use a Javascript file to actually accomplish anything with PhantomJS.

Here is a very simple version of the script you can use

Code mostly copied from https://stackoverflow.com/a/12469284/4499924

printSource.js

var system = require('system');
var page   = require('webpage').create();
// system.args[0] is the filename, so system.args[1] is the first real argument
var url    = system.args[1];
// render the page, and run the callback function
page.open(url, function () {
  // page.content is the source
  console.log(page.content);
  // need to call phantom.exit() to prevent from hanging
  phantom.exit();
});

To print the page source to standard out.

To save the page source in a file

phantomjs printSource.js http://todomvc.com/examples/emberjs/ > ember.html
