我创建了一个 LocalStorage 示例。当我使用 Chrome 网络浏览器时，它工作正常。但是当我在 iPhone 模拟器上测试时，它没有。请帮忙。 这是我设置本地存储值的代码:
function onclick(){
window.localStorage.setItem("data","Nguyen Minh Binh");
}

<a data-role="button" href="DemoWOrklightJQM/index.html" data-prefetch onclick="onclick()">Click me</a>

这是我试图获取保存数据的代码:

<script>
$(document).ready(function(){

$("#mysavedData").html(window.localStorage.getItem("data"));
});
</script>

<a href="#" onclick="getData(); return false;" data-role="button" id="button" data-theme="a" data-icon="home" data-iconpos="left" data-corners="true">Button</a>
</div>
</div>
</body>
</html>
编辑: 在 Whizkid747 的建议下，我按如下方式更改了脚本源，但它仍然不起作用。
<!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="shortcut icon" href="images/favicon.png">
<link rel="apple-touch-icon" href="images/apple-touch-icon.png">
<link href="jqueryMobile/jquery.mobile-1.3.0.css" rel="stylesheet">
<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">
function onLoad(){
document.addEventListener("deviceready", deviceready, false);
}
function deviceready(){
$("#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>
<a href="#" onclick="getData(); return false;" data-role="button" id="button" data-theme="a" data-icon="home" data-iconpos="left" data-corners="true">Button</a>
</div>
</div>
</body>
</html>
EDIT2:尝试在 OnDeviceReady 中设置 localStorage，然后在下一行获取它，但仍然不起作用。
<!DOCTYPE html>
<html>
<head>
<title>Contact Example</title>
<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 src="https://raw.github.com/phonegap/phonegap/2.5.0rc1/lib/android/cordova-2.5.0rc1.js"></script>
<script type="text/javascript" charset="utf-8">
// Wait for PhoneGap to load
//
document.addEventListener("deviceready", onDeviceReady, false);
// PhoneGap is ready
//
function onDeviceReady() {
window.localStorage.setItem("key", "minhbinh");
var keyname = window.localStorage.key(i);
// keyname is now equal to "key"
var value = window.localStorage.getItem("key");
// value is now equal to "value"
window.localStorage.removeItem("key");
window.localStorage.clear();
// localStorage is now empty
$("p#p1").text(value);
}
</script>
</head>
<body>
<h1>Example</h1>
<p id="p1">localStorage</p>
</body>
</html>
最佳答案
将 document.ready 中的代码移至 onDeviceReady event of PhoneGap . onDeviceReady 是您需要开始执行自定义代码的时间。
编辑: *尝试使用本地添加的 cordova.js 而不是来自 github 的以下代码*
<!DOCTYPE html>
<html>
<head>
<title>Contact Example</title>
<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 src="cordova-2.5.0rc1.js"></script>
</head>
<body>
<h1>Example</h1>
<p id="p1">localStorage</p>
<script type="text/javascript">
// Wait for PhoneGap to load
document.addEventListener("deviceready", onDeviceReady, false);
// PhoneGap is ready
function onDeviceReady() {
window.localStorage.setItem("key", "minhbinh");
var keyname = window.localStorage.key(i);
// keyname is now equal to "key"
var value = window.localStorage.getItem("key");
// value is now equal to "value"
//window.localStorage.removeItem("key");
//window.localStorage.clear();
// localStorage is now empty
$("p#p1").text(value);
}
</script>
</body>

关于html - LocalStorage 不适用于 PhoneGap，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/15600432/
