由于您正在尝试装载的PhoneGap /科尔多瓦框架之前显示警报。
$（文件）。就绪（函数（）{的是不会帮助你在这里，你必须使用此事件来检查的PhoneGap加载成功：
document.addEventListener（deviceReady，deviceReady，FALSE）;功能deviceReady（）{
//现在可以安全地使用PhoneGap的API
}

的PhoneGap由两code碱基：本地和JavaScript。而
本土code加载时，会显示自定义的加载图片。然而，
JavaScript是只装载一次的DOM负荷。这意味着你的网站
应用程序可以潜在地调用PhoneGap的JavaScript函数
之前加载它。why phonegap doesn't show alert notification ? (running on iPhone 5.1.1 , phonegap phonegap-2.1.0-0-g26d211b, mountain lion 10.8.2, xcode 4.4.1)
<html> <head> <link rel="stylesheet" href="themes/css/apple.css" title="jQTouch"> <script src="src/lib/zepto.min.js" type="text/javascript" charset="utf-8"></script> <script src="cordova-2.1.0.js" type="text/javascript" charset="utf-8"></script> <script src="src/jqtouch.min.js" type="text/javascript" charset="utf-8"></script> <script type="text/javascript"> $(document).ready(function(){ try { navigator.notification.alert('Hello', ok, 'Title', 'Button!'); } catch(e) { alert("doesn't support!!"); } } function ok() {} </script> </head> </html>
解决方案Because you are trying to show an alert before phonegap/cordova framework is loaded.
$(document).ready(function(){ is not going to help you here, you must use this event to check if phonegap is successfully loaded:
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
PhoneGap consists of two code bases: native and JavaScript. While the native code is loading, a custom loading image is displayed. However, JavaScript is only loaded once the DOM loads. This means your web application could, potentially, call a PhoneGap JavaScript function before it is loaded.
