This is a wrapper the Pikaday library, for use with Ur/Web.
Pikaday, by David Bushell, is a simple JavaScript library providing a datepicker widget. It has no dependencies on any other JavaScript libraries, and it uses "modular" CSS:

Many thanks to:
-
Istvan Chung for his Pull Request getting this to work.
-
Ziv Scully for his explanation of the use of node id's in Ur/Web and his initial suggestion to use the tag:
<active code ={init nid; return <xml/>}>
The Pull Request from Istvan has now been merged, correcting the previous errors in my Ur/Web (and JavaScript) code. The code now compiles and runs correctly - currently using Ur/Web's file directive as also suggested by Istvan, to serve the "static" JavaScript and CSS files.
(Later, in production, a webserver such as nginx can be used to serve the static files.)
Note:
In my testing, I compiled this without using the Makefile provided by Istvan, since I was unsure how to use it.
To Do:
Currently, the handler merely echoes back the date as a string in a human-readable format (eg, "Sat Aug 08 2015").
Later, if it is desired to use the date in an SQL database, it will probably be necessary to convert the date to a format suitable for Postgres, eg:
