Overview

This code snippet shows how to list calendar entries using the Calendar Platform Service for Symbian Web Runtime. The service was 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

<input type="radio" name="eventType" id="meeting" checked
onclick="showEntries();">
<label for="meeting">Meetings</label><br />
 
<input type="radio" name="eventType" id="anniversary"
onclick="showEntries();">
<label for="anniversary">Anniversaries</label><br />
 
<input type="radio" name="eventType" id="dayEvent"
onclick="showEntries();">
<label for="dayEvent">Day Events</label><br />
 
<input type="radio" name="eventType" id="reminder"
onclick="showEntries();">
<label for="reminder">Reminders</label><br />
 
<input type="radio" name="eventType" id="toDo"
onclick="showEntries();">
<label for="toDo">ToDos</label><br />
 
<label for="entriesList">Entries:</label><br />
<select size="2" id="entriesList"></select><br />

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;
}
}
 
function showEntries() {
var criteria = new Object();
var filter = new Object();
if (document.getElementById("meeting").checked) {
filter.Type = "Meeting";
} else if (document.getElementById("anniversary").checked) {
filter.Type = "Anniversary";
} else if (document.getElementById("dayEvent").checked) {
filter.Type = "DayEvent";
} else if (document.getElementById("reminder").checked) {
filter.Type = "Reminder";
} else if (document.getElementById("toDo").checked) {
filter.Type = "ToDo";
}
criteria.Filter = filter;
criteria.Type = "CalendarEntry";
 
// Get the list of entries
try {
var result = serviceObj.IDataSource.GetList(criteria);
if (result.ErrorCode == 0) {
displayEntries(result.ReturnValue);
} else {
alert("Error in getting calendar entries.");
}
} catch(exception) {
alert("Error in getting calendar entries: " + result.ErrorMessage);
}
}
 
function displayEntries(iterator) {
var entriesList = document.getElementById("entriesList");
 
// Empty the entries list
while (entriesList.length != 0) {
entriesList.remove(0);
}
 
// Set the pointer to the first element
iterator.reset();
 
var item;
while ((item = iterator.getNext()) != undefined) {
var msg = "";
msg = msg + "Type: " + item['Type'];
msg = msg + "Summary: " + item['Summary'];
// The commented code shows available fields that can be retrieved
//msg = msg + "StartTime: " + item['StartTime'];
//msg = msg + "EndTime: " + item['EndTime'];
//msg = msg + "Id: " + item['Id'];
//msg = msg + "LocalId: " + item['LocalId'];
var node = document.createElement("option");
node.value = item['LocalId'];
node.appendChild(document.createTextNode(msg));
entriesList.appendChild(node);
}
}
