请查看并帮我解决此问题。我花了2天头痛。永远不会调用onDeviceReady函数。 这是我的代码:
<!DOCTYPE HTML>
<html>
<head>
<meta charset="UTF-8">
<title>DemoSimpleControls</title>
<meta name="viewport"
content="width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=0">

<link rel="stylesheet" href="css/DemoSimpleControls.css">
<script src="jqueryMobile/jquery.mobile-1.3.0.js"></script>
<script src="../js/jquery-1.9.1.min.js"></script>
< script type="text/javascript" charset="utf-8" src="../cordova-2.5.0.js"></script>
<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
// Handler for .ready() called.
document.addEventListener("deviceready", onDeviceReady, true);
});
$(function() {
document.addEventListener("deviceready", onDeviceReady, true);
});
function onDeviceReady(){
alert("ready");
$("#mysavedData").html("XYZ");
$("#mysavedData").html(window.localStorage.getItem("data"));
}
</script>
</head>
<body id="content" onLoad="onLoad();" >
<div data-role="page" id="page">
<div data-role="header" >
<a data-rel="back" href="#" >Back</a>
<h1>My page</h1>
</div>
<div data-role="content" style="padding: 15px" data-theme="e">
<div id="mysavedData">My data</div>
</div>
</div>
</body>
</html>

那个事件太可怕了,有很多问题,不值得使用它。相反,只需通过检查window.device
即可轮询,直到PhoneGap准备就绪。
function initializePhoneGap( success, failure ) {
var timer = window.setInterval( function () {
if ( window.device ) {
window.clearInterval( timer );
success();
};
}, 100 );
window.setTimeout( function () { //failsafe
if ( !window.device ) { //phonegap failed
window.clearInterval( timer );
failure();
};
}, 5000 ); //5 seconds
};
window.onload = function () {
initializePhoneGap( function success() {
//start app
document.getElementById( 'result' ).textContent = 'phonegap: success';
}, function failure() {
//phonegap failed
document.getElementById( 'result' ).textContent = 'phonegap: failure';
} );
};
should fail on desktop after 5 seconds
<div id="result">phonegap:</div>

请看PhoneGap网站上的以下示例。将事件侦听器放在onLoad()中并从jQuery ready函数中删除它。
<script type="text/javascript" charset="utf-8" src="cordova-2.5.0.js"></script>
<script type="text/javascript" charset="utf-8">
// Call onDeviceReady when Cordova is loaded.
//
// At this point, the document has loaded but cordova-2.5.0.js has not.
// When Cordova is loaded and talking with the native device,
// it will call the event `deviceready`.
//
function onLoad() {
document.addEventListener("deviceready", onDeviceReady, false);
}
// Cordova is loaded and it is now safe to make calls Cordova methods
//
function onDeviceReady() {
// Now safe to use the Cordova API
}
</script>
说明: Cordova包含两个代码库:本机代码和JavaScript代码。在加载本机代码时,会显示自定义加载图像。但是,只有在DOM加载后才会加载JavaScript。这意味着您的Web应用程序可能会在加载之前调用Cordova JavaScript函数。
当Cordova满载时,Cordova deviceready事件将会激活。设备触发后,您可以安全地调用Cordova功能。
通常,一旦HTML文档的DOM加载,您将需要使用document.addEventListener附加事件侦听器。

此代码适用于我
<body onload="init()"></body>
function init() {
document.addEventListener("deviceready", onDeviceReady, false);
}
function onDeviceReady() {
// Now safe to use the Cordova API
}
快乐的编码.......

您似乎不知道要触发此活动,您还需要包含 phonegap.js
文件,
并且还像我一样使用它,以便首先加载视图然后应用程序处理phonegap,否则用户将不得不等待更多。
