Because you are trying to show an alert before phonegap/cordova framework is loaded. 因为您在加载phonegap / cordova框架之前尝试显示警报。

$(document).ready(function(){ is not going to help you here, you must use this event to check if phonegap is successfully loaded: $（document）.ready（function（）{在这里不会帮到你，你必须使用这个事件检查phonegap是否成功加载：

document.addEventListener("deviceReady", deviceReady, false);

function deviceReady() {
    // Now safe to use the PhoneGap API
}

More about this event: http://docs.phonegap.com/en/1.0.0/phonegap_events_events.md.html 有关此活动的更多信息： http ： //docs.phonegap.com/en/1.0.0/phonegap_events_events.md.html

PhoneGap consists of two code bases: native and JavaScript. PhoneGap包含两个代码库：本机和JavaScript。 While the native code is loading, a custom loading image is displayed. 在加载本机代码时，会显示自定义加载图像。 However, JavaScript is only loaded once the DOM loads. 但是，只有在DOM加载后才会加载JavaScript。 This means your web application could, potentially, call a PhoneGap JavaScript function before it is loaded. 这意味着您的Web应用程序可能会在加载之前调用PhoneGap JavaScript函数。
