chrome 桌面通知 Notifications 用法

<script>
function notify(title,content,icon) {
if (window.webkitNotifications) {
if (window.webkitNotifications.checkPermission() == 0) {
var notification_test = window.webkitNotifications.createNotification(icon, title, content);
notification_test.display = function() {}
notification_test.onerror = function() {}
notification_test.onclose = function() {}
notification_test.onclick = function() {this.cancel();}

notification_test.replaceId = 'Meteoric';

notification_test.show();

} else {
window.webkitNotifications.requestPermission(notify);
}
