Correct way of using JQuery
What is the correct way (to this date) to use JQuery Mobile and Phonegap together?
Both frameworks need to load before they can be used. How can I be sure that both are loaded before I can use them?
您可以使用JQuery的延期功能。
var deviceReadyDeferred = $.Deferred();
var jqmReadyDeferred = $.Deferred();
document.addEventListener("deviceReady", deviceReady, false);
function deviceReady() {
deviceReadyDeferred.resolve();
}
$(document).one("mobileinit", function () {
jqmReadyDeferred.resolve();
});
$.when(deviceReadyDeferred, jqmReadyDeferred).then(doWhenBothFrameworksLoaded);
function doWhenBothFrameworksLoaded() {
// TBD
}
基于上面的例子，以下是它的工作原理
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; 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/bootstrap.css" />
<title>InforMEA</title>
</head>
<body>
<script type="text/javascript" src="js/jquery-1.8.3.js"></script>
<script type="text/javascript">
var dd = $.Deferred();
var jqd = $.Deferred();
$.when(dd, jqd).done(doInit);
$(document).bind('mobileinit', function () {
jqd.resolve();
});
</script>
<script type="text/javascript" src="js/jquery.mobile-1.2.0.js"></script>
<script type="text/javascript" src="cordova-2.2.0.js"></script>
<script type="text/javascript">
document.addEventListener('deviceready', deviceReady, false);
function deviceReady() {
dd.resolve();
}
function doInit() {
alert('Ready');
}
</script>
</body>
</html>
为了使用jquery mobile的phonegap，你需要像这样使用它
<head>
<title>Index Page</title>
<!-- Adding viewport -->
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="viewport" content="width=device-width, user-scalable=no">
<!-- Adding jQuery scripts -->
<script type="text/javascript" src="jquery/jquery-1.7.1.min.js"></script>
<!-- Since jQuery Mobile relies on jQuery core's $.ajax() functionality,
$.support.cors & $.mobile.allowCrossDomainPages must be set to true to tell
$.ajax to load cross-domain pages. -->
<script type="text/javascript">
$(document).bind("mobileinit", function() {
$.support.cors = true;
$.mobile.allowCrossDomainPages = true;
});
</script>
<!-- Adding Phonegap scripts -->
<script type="text/javascript" charset="utf-8"
src="cordova/cordova-1.8.0.js"></script>
<!-- Adding jQuery mobile scripts & CSS -->
<link rel="stylesheet" href="jquerymobile/jquery.mobile-1.1.0.min.css" />
<script type="text/javascript"
src="jquerymobile/jquery.mobile-1.1.0.min.js"></script>
</head>
<script type="text/javascript">
// Listener that will invoke the onDeviceReady() function as soon as phonegap has loaded properly
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
navigator.splashscreen.hide();
document.addEventListener("backbutton", onBackClickEvent, false); // Adding the back button listener
}
</script>
<body>
<div data-role="page" id="something" data-ajax="false">
<script type="text/javascript">
$("#something").on("pageinit", function(e) {
});
$("#something").on("pageshow", function(e) {
});
$("#something").on("pagebeforeshow", function(e) {
});
</script>
<div data-role="header">
</div>
<div data-role="content">
</div>
</div>
</body>
