我正在尝试使用 phonegap,但由于某种原因我的 javascript 没有运行。到目前为止我尝试过的是:

<html>
<head>
<meta charset="utf-8" />
<meta name="format-detection" content="telephone=no" />
<meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi" />
<link rel="stylesheet" type="text/css" href="css/index.css" />
<title>Hello World</title>

<script type="text/javascript" src="phonegap.js"></script>
<script type="text/javascript" charset="utf-8">
document.addEventListner("deviceready", onDeviceReady, false);

function onDeviceReady() {
alert('hey');
document.addEventListener("online", onOnline, false);
document.addEventListener("offline", onOffline, false);
}

function onOnline() {
alert('device is online');
}

function onOffline() {
alert('device is offline');
}
</script>
</head>
<body>
<div class="app">
<h1>PhoneGap</h1>
<div id="deviceready" class="blink">
<p class="event listening">Connecting to Device</p>
<p class="event received">Device is Ready</p>
</div>
</div>
</body>

但出于某种原因我没有收到警报。我在 IOS 7 上使用 phonegap 2.9.0

我也试过的是:

<html>
<head>
<meta charset="utf-8" />
<meta name="format-detection" content="telephone=no" />
<meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi" />
<link rel="stylesheet" type="text/css" href="css/index.css" />
<title>Hello World</title>

<script type="text/javascript" src="phonegap.js"></script>
<script type="text/javascript" charset="utf-8">
document.addEventListener("deviceready", onDeviceReady, false);

// PhoneGap is ready
//
function onDeviceReady() {
// Empty
}

// alert dialog dismissed
function alertDismissed() {
// do something
}

// Show a custom alert
//
function showAlert() {
navigator.notification.alert(
'You are the winner!', // message
alertDismissed, // callback
'Game Over', // title
'Done' // buttonName
);
}
</script>
</head>
<body>
<div class="app">
<h1>PhoneGap</h1>
<div id="deviceready" class="blink">
<p class="event listening">Connecting to Device</p>
<p class="event received">Device is Ready</p>
<p><a href="#" onclick="showAlert(); return false;">Show Alert</a></p>
</div>
</div>
</body>

最佳答案

        document.addEventListener("online", onOnline, false);
document.addEventListener("offline", onOffline, false);

这些函数将仅用于建立新的互联网连接和禁用网络连接

当您打开应用程序时,它不会工作。这些“在线”和“离线”事件监听器主要用于跟踪互联网连接是否可用。

此外,您不应使用 ios 7 可能不支持的警报功能。使用 phonegap 中的通知类进行警报
