app.initialize();
</script>

}
document.addEventListener("deviceready", showAlert('You are the winner!'), false);
app.initialize();
</script>

我确定我错过了什么……只是我无法断定是什么。请帮帮我。

Answer 1

这将立即调用 showAlert，而不是延迟到事件触发时:

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

改为这样做

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