How to get file extension

[AlexStenAlexSten]

hello,
I'm working with Forms Designer from few months and would need some help.
Is it possible in a document library, via Forms Designer, to get the file name with extension in the field "NAME"?
I can create a custom view in SharePoint displaying more NAME fields, with file extension, but I don't know how to get this info in Forms Designer.
My task is to have in FD the field "NAME" with link to the file and the file type. Or at least to have the "File Type" in another field in the form.

Hi,
Not sure that I got you. Where do you want to display an extension - in a Related Items control or as a separate field in a form?

hi Dmtry,
I'd need to display the extension or the full filename + extension in a separate field in the form.
I will have to get the file extension, because based on the extension, I will enable or disable by code some features (ie. save the form data).
Hope this is more clear. Thank you

Hi Alex,
You can get an extension from the FileLeafRef control via JavaScript:

Code: Select all

fd.field('FileLeafRef').control()._el().find('.ms-fileField-fileExt').text()

Thank you very much Dmitry. It works well!
Just for "contribute" to the forum in some way, below the solution I was working on. As you can see it works, but is much more complex than yours.
Thanks a lot
