推荐答案

您需要使用多种技术:

• JavaScript最好通过JSON格式通过AJAX数据从服务器加载.您应该考虑使用 jQuery 或Sencha ExtJS来简化AJAX和JSON处理.
• 取决于数据的复杂性，您可以使用webstorages或indexedDB在本地存储数据.越复杂，您对indexedDB的满意度就越高，因为它允许您拥有索引和某种加速的过滤.如果您使用jQuery，请使用 indexedDB插件来简化生活.
• 要显示，添加，编辑和总体上离线处理数据，请考虑构建表单，表格并使它们可排序. jQuery也可以帮助您构建它.尽管Sencha ExtJS具有非常好的表配置器.
• 将数据上传到服务器需要某种同步逻辑，最好是服务器端，以保持对数据验证的控制权.您还可以使用JSON，JSON易于在服务器端以任何服务器端语言生成和解析.

• Javascript loads via AJAX data from your server, best using JSON format. You should consider jQuery or Sencha ExtJS to ease AJAX and JSON handling.
• Than you can store the data localy using webstorages or indexedDB, depending on the complexity of your data. The more complex, the more happy you might be with indexedDB as it allows you to have indexes and some sort of accelerated filtering. If you use jQuery take a indexedDB plugin to ease your live.
• To show, add, edit and in general manipulate your data offline, consider to build your forms, tables, make them sortable. jQuery can help you to build this up too. Although Sencha ExtJS has a very nice table configurator.
• uploading data to your server needs some kind of synchronisation logics, best server side, to keep the control over the validation of data central. You can work with JSON as well, its easy to generate and to parse at server side, in any server-side language.

如果您没有喜欢的Javascript库并且对这一切不熟悉，请看一下jQuery.它还可能会教您基础技术. Sencha只会对您隐藏技术，这在某种程度上是不好的"，因为它会使您视而不见，并且很难甚至有时无法完成非常复杂的任务.

If you don't have a favorite Javascript lib and you are new to all this, have a look at jQuery. It also might teach you the underlaying technologies. Sencha will only hide the technology from you, which is somehow "bad", as it keeps you blind and it can be hard or sometimes impossible to accomplish very complex tasks.

实际上，您需要学习Javascript，因为它是人们认为html5的核心.

Actually what you need is to learn Javascript, as its the core of what people think is html5.
