    <p>I am trying to get the device ready event to work on the phonegap 3 helloworld default app.</p> <p>html</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;meta charset="utf-8" /&gt; &lt;meta name="format-detection" content="telephone=no" /&gt; &lt;meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi" /&gt; &lt;link rel="stylesheet" type="text/css" href="css/index.css" /&gt; &lt;title&gt;Hello World&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;div class="app"&gt; &lt;h1&gt;PhoneGap&lt;/h1&gt; &lt;div id="deviceready" class="blink"&gt; &lt;p class="event listening"&gt;Connecting to Device&lt;/p&gt; &lt;p class="event received"&gt;Device is Ready&lt;/p&gt; &lt;/div&gt; &lt;/div&gt; &lt;script type="text/javascript" src="phonegap.js"&gt;&lt;/script&gt; &lt;script type="text/javascript" src="js/index.js"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; app.initialize(); &lt;/script&gt; &lt;/body&gt; </code></pre> <p></p> <p>javascript</p> <pre><code>var app = { // Application Constructor initialize: function() { this.bindEvents(); }, // Bind Event Listeners // // Bind any events that are required on startup. Common events are: // 'load', 'deviceready', 'offline', and 'online'. bindEvents: function() { document.addEventListener('deviceready', this.onDeviceReady, false); }, // deviceready Event Handler // // The scope of 'this' is the event. In order to call the 'receivedEvent' // function, we must explicity call 'app.receivedEvent(...);' onDeviceReady: function() { app.receivedEvent('deviceready'); alert('welcome!'); }, // Update DOM on a Received Event receivedEvent: function(id) { var parentElement = document.getElementById(id); var listeningElement = parentElement.querySelector('.listening'); var receivedElement = parentElement.querySelector('.received'); listeningElement.setAttribute('style', 'display:none;'); receivedElement.setAttribute('style', 'display:block;'); console.log('Received Event: ' + id); } }; </code></pre> <p>This code works ok and will fire my welcome alert when I open the app. However if I comment out either of the lines:</p> <pre><code>&lt;p class="event listening"&gt;Connecting to Device&lt;/p&gt; &lt;p class="event received"&gt;Device is Ready&lt;/p&gt; </code></pre> <p>The welcome alert will no longer fire. What is going on here I have no idea what mechanism phonegap is using to create this kind of behavior?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
