<input type="checkbox" id="cb1" name="cb1" value="Checkbox 2" />
<input type="checkbox" id="cb2" name="cb2" value="Checkbox 3" />
</div>
</body>

Source: JavaScript

// Initializes the widget
function init() {
for (var i = 0; i < CHECKBOXES; i++) {
checkboxes[i] = new Nokia.CheckBox({
element: "#cb" + i,
label: "Checkbox " + (i + 1),
wrapper: "div"
});
}
}

To find out whether the checkbox has been checked, use the isChecked() method:

// Shows the checked boxes.
function executeSnippet() {
var checkboxesChecked = 0;
for (var i = 0; i < checkboxes.length; i++) {
if (checkboxes[i].isChecked()) {
checkboxesChecked++;
}
}
displayNote("Checked checkboxes: " + checkboxesChecked);
}

Postconditions

A Guarana UI checkbox is added on the web page. When Options > Execute snippet is selected, the number of checked checkboxes is displayed.
