HTML5 webstorage

Is it possible to give an offline HTML5 form to the end user like Excel file using storage mechanism?. So that he can fill the form and upload it to the J2ee based site.

In Excel this is possible. User can download the format of excel file, fills it and upload to the website. Later in servlet we read the contents and store them in DB.

Is same thing poss开发者_Python百科ible with HTML5?

Yes it is. You have to build the application as an offline application. While the user is updating is data, you serialize it to the webstorage. As soon as you have internet connectivity, just send the serialized that to the server to be parsed.
