Answer 1

The reason is because there is no built-in support for alert in Windows Phone 7 and 8. Use PhoneGap's Notification API instead, and have something like this: 原因是因为Windows Phone 7和8中没有内置的alert支持。请改用PhoneGap的Notification API ，并进行如下操作：

document.addEventListener('deviceready', onDeviceReady, false);

function onDeviceReady() {
    window.alert = window.alert || navigator.notification.alert;
    alert('button working fine!');
}
