HTML5的Web Storage API提供了两种客户端存储数据的方法

localStorage和sessionStorage。 localStorage没有时间限制，程序升级也不会消失，可以满足持久化需求。

设置localStorage的方法

window.localStorage.setItem("likecolor","red");

获得localStorage的方法

window.localStorage.getItem("likecolor");

完整的Code如下：

<!DOCTYPE html>

<html>

<head>

    <meta charset="utf-8" />

    <meta name="format-detection" content="telephone=no" />

    <meta name="msapplication-tap-highlight" content="no" />

    <meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width" />

    <meta http-equiv="Content-Security-Policy" content="default-src * 'unsafe-inline'; style-src 'self' 'unsafe-inline'; media-src *" />

    <link rel="stylesheet" href="css/jquery.mobile-1.4.5.min.css">

    <script type="text/javascript" src="js/jquery.js"></script>

    <script  type="text/javascript" src="js/jquery.mobile-1.4.5.min.js"></script>

    <script type="text/javascript" charset="utf-8" src="cordova.js" ></script>

    <title>Hello World</title>
 
    <script type="text/javascript" charset="utf-8">

        document.addEventListener('deviceready', onDeviceReady, false);

        function onDeviceReady(){

             $(".localStorageBtn").bind("click",function(event,ui){

                  setLocalStorage();

             });
 
             $(".showLocalStorageBtn").bind("click", function(event, ui ) {

                  getLocalStorage();

             });

        }
 
         function setLocalStorage(){

            window.localStorage.setItem("likecolor","red");

         }
 
         function getLocalStorage(){

             var item = window.localStorage.getItem("likecolor");

             var info = document.getElementById("info");

             info.innerHTML = item;

         }

    </script>

</head>
 
<body>

<div id="page1" data-role="page" data-add-back-btn="true">

    <header data-role="header"><h1>Head</h1></header>

    <div data-role="content">

        <a data-role="button" class="localStorageBtn">set Local Storage</a>

        <a data-role="button" class="showLocalStorageBtn">get Local Storage</a>

        <p id="info"/>

    </div>

    <footer data-role="footer"><h1>Footer</h1></footer>

</div>
 
</body>
 
</html>
