Question

我使用Telerik Icenium创建移动应用程序，它只涉及Cordova和Jquery移动应用程序。

在首页上我有一个像这样的listView

<ul data-role="listview">
                <li><a href="#OpenProject?pid=1" data-transition="slide">Project 1</a></li>
                <li><a href="#OpenProject?pid=2" data-transition="slide">Project 2</a></li>
            </ul>

我想从本地存储加载，然后当用户选择时，我会将其与我的API同步。

使用localstorage并从那里获取项目是一种好方法吗？如果是这样，任何人都可以给我一个很好的方法来加载从本地json文件或从移动设备上的本地数据库到listView的项目。

我为你做了一个工作的例子：http://jsfiddle.net/Gajotres/W3YDd/

$(document).on('pagebeforeshow', '#index', function(){       
        if(typeof(Storage)!=="undefined") {
            localStorage.jsonExample='[{"score":null,"popularity":3,"translated":true,"adult":false,"language":"en","original_name":"The Goonies","name":"The Goonies","alternative_name":"Балбесы","movie_type":"movie","id":9340,"imdb_id":"tt0089218","url":"http://www.themoviedb.org/movie/9340","votes":43,"rating":8.5,"certification":"PG","overview":"A young teenager named Mikey Walsh finds an old treasure map in his fathers attic.

        }

    var jsonObject = jQuery.parseJSON(localStorage.jsonExample);

    $('#movie-data').append('<li>Movie name:<span> ' + jsonObject[0].original_name+ '</span></li>');
    $('#movie-data').append('<li>Popularity:<span> ' + jsonObject[0].popularity + '</span></li>');
    $('#movie-data').append('<li>Rating:<span> ' + jsonObject[0].rating+ '</span></li>');
    $('#movie-data').append('<li>Overview:<span> ' + jsonObject[0].overview+ '</span></li>');
    $('#movie-data').append('<li>Released:<span> ' + jsonObject[0].released+ '</span></li>');  
    $('#movie-data').listview('refresh'); 
});

为了更好地澄清，这个例子是从我的另一个例子中创建的：

在此示例中，json是从远程源获取的。但基本原则是一样的。
