How to get file creation date on server for jQuery/uploadify?

开发者 https://www.devze.com 2023-01-31 18:41 出处：网络

I am using the jQuery Uploadify plugin on a web page to transfer files from the local computer to an ASP.NET MVC2 control action method. Is there a way to transfer the creation d开发者_开发技巧ate/tim

I can get at the data in an Uploadify event on the client, but can not figure out how to "package" that data so it is moved to the server w/ the file.

Any thoughts appreciated.

Try using onSelect event to add values to the scriptData object.

UPDATE: The following is an ad-hoc view to pass the data to the action. It appears that modificationDate returns a Unix timestamp in it's time field and you'll have to convert it on the server side. I wasn't able to find any documentation on modificationDate property.

In your action method, you can grab timestamp through the Request.Form["modifiedTimestamp"]. Check here on how to convert timestamp to the DateTime object.
