Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We can launch the PhantomJS REPL from the command line using the phantomjs command."

A block of code is set as follows:

var system = require('system');
system.args.forEach(function(arg, i) {
  console.log(i + ' = ' + arg);
});
phantom.exit();

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

phantom.onError = function onErrorFn(msg, trace) {
  console.error('[PHANTOMJS ERROR] ' + msg);
  phantom.exit(1);
};

Any command-line input or output is written as follows:

phantomjs --cookies-file=cookie-jar access-secure-site.js

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Lastly, click on Save to persist the changes to this job."

Note

Warnings or important notes appear in a box like this.
