Overview
This code snippet demonstrates how to add a busy indicator on a web page using Guarana UI components. The busy indicator looks like this:
You can download the component library from Guarana UI: a jQuery-Based UI Library for Nokia WRT.
Source: Relevant HTML components
<head>
<!-- Guarana UI style sheets -->
<link rel="stylesheet"
href="style/themes/themeroller/default-theme/ui.all.css"
type="text/css" media="screen">
<!-- Guarana UI scripts -->
<script type="text/javascript" src="lib/jquery/jquery.js"
charset="utf-8"></script>
<script type="text/javascript" src="lib/guarana/defaults.js"
charset="utf-8"></script>
<script type="text/javascript" src="lib/guarana/core.js"
charset="utf-8"></script>
</head>
<body>
<div id="bodyContent" class="bodyContent">
<div id="busyIndicatorContainer"></div>
</div>
</body>
Source: Relevant CSS declarations
#busyIndicatorContainer {
position: absolute;
top: 50%;
left: 50%;
width: 0;
height: 0;
}
Source: JavaScript
// Initializes the widget
function init() {
createMenu();
window.busyIndicator = new Nokia.Busy({
element: "#busyIndicatorContainer",
autoOpen: false
});
}
// Executes the snippet.
// Shows the busy indicator and hides it after 2 seconds.
function executeSnippet() {
window.busyIndicator.show();
setTimeout(function() {
window.busyIndicator.hide();
}, 2000);
}
The executeSnippet() function above shows the busy indicator (the show() method) and hides it after 2 seconds (the hide() method).
Note: The busy indicator component requires the following files from the library:
