Simulating keyboard input in PhantomJS

In this recipe, we will demonstrate how to perform keyboard input in a PhantomJS script.

Getting ready

To run this recipe, we will need a script that loads a web page, and that page will need some element where we can perform text input.

The script in this recipe is available in the downloadable code repository as recipe08.js under chapter03. If we run the provided example script, we must change to the root directory for the book's sample code.

Lastly, the script in this recipe runs against the demo site that is included with the cookbook's sample code repository. To run that demo site, we must have Node.js installed. In a separate terminal, change to the phantomjs-sandbox directory (in the sample code's directory), and start the app with the following command:

node app.js

How to do it…

Consider the following script:

var webpage = require('webpage').create();

webpage.viewportSize = { width: 1280, height: 800 };
function getStageValue() {
  return webpage...
