Overview
This code example shows how to add a checkbox on a web page using Guarana UI components. The checkbox component looks like this:
You can download the component library from Guarana UI: a jQuery-Based UI Library for Nokia WRT.

<link rel="stylesheet"

<div id="bodyContent" class="bodyContent">
<input type="checkbox" id="cb0" name="cb0" value="Checkbox 1" />
<input type="checkbox" id="cb1" name="cb1" value="Checkbox 2" />
<input type="checkbox" id="cb2" name="cb2" value="Checkbox 3" />
</div>
</body>
Source: JavaScript
var CHECKBOXES = 3;
var checkboxes = [];
Nokia.use("optiongroup", "checkbox", init);
// 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 if 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);
}
