Overview

This code snippet shows how to list calendars by using the Calendar Platform Service for S60 Web Runtime introduced in S60 5th Edition.

The device.getServiceObject("Service.Calendar", "IDataSource") method is used to obtain access to the service object for the Calendar Service API.

Source: Relevant HTML components

<label for="calendarList">Calendars:</label><br />
<select size="2" id="calendarList" onclick="showEvents();"></select>

Source: JavaScript file

var serviceObj = null;
 
window.onload = init;
 
// Initializes the widget
function init() {
    // Obtain the service object
    try {
        serviceObj = device.getServiceObject("Service.Calendar",
            "IDataSource");
    } catch (ex) {
        alert("Service object cannot be found.");
        return;
    }
 
    listCalendars(); 
}
 
function listCalendars() {
    try {
        var filter = new Object();
        // Not using the default calendar
        filter.DefaultCalendar = false;
 
        // Criteria for fetching calendars
        var criteria = new Object();
        criteria.Type = "Calendar";
        criteria.Filter = filter;
 
        // Get the list of calendars
        result = serviceObj.IDataSource.GetList(criteria);
        if (result.ErrorCode == 0) {
            showCalendars(result.ReturnValue);
        } else {
            alert("Error in getting calendars");
        }
    } catch( exception ) {
        alert("initialize error: " + exception);
    }
}
 
function showCalendars(iterator) {
    var calendarList = document.getElementById("calendarList");
 
    // Empty the calendar list
    while (calendarList.length != 0) {
        calendarList.remove(0);
    }
 
    // Set the pointer to the first element
    iterator.reset();
 
    var item;
    while ((item = iterator.getNext()) != undefined) {
        var node = document.createElement("option");
        node.value = item;
        node.appendChild(document.createTextNode(item));
        calendarList.appendChild(node);
    }
}
