Time for action – handling device orientation with JavaScript


Execute the following steps:

  1. Open the command-line tool and create a new PhoneGap project named orientationevents, and add the platforms you want to target for this example.

  2. Install the plugin to your project:

    $ phonegap plugin add cordova-plugin-device-motion
    
  3. Go to the www folder, open the index.html file, and add div with the #orientation ID inside the main div of the app beneath #deviceready:

    <div class="app">
        <h1>Apache Cordova</h1>
        <div id="deviceready">
            ......
        </div>
        <div id="orientation">
        </div>
    </div>
  4. Go to the css folder and define two new rules inside the index.css file to give a border and a bigger font size to div and its content. You can even add the CSS styles directly to the head section of your HTML page:

    #orientation{
    
        width: 230px;
        border: 1px solid rgb(10, 1, 1);
    
    }
    
    #orientation p{
        font-size: 36px;
        font-weight: bold;
       ...
