This will call showAlertimmediately, instead of delaying to when the event fires:

这将showAlert立即调用，而不是延迟到事件触发时：

document.addEventListener("deviceready", showAlert('You are the winner!'), false)

Instead do this

而是这样做

document.addEventListener("deviceready", function() {
    showAlert('You are the winner!')
}, false)
