Use javascript to add list of announcements pulled from http://mathmeetings.net/at-gt.json.
This is created by adding javascript code to the document header, and then an empty div to the html body.
This one uses a query string to show conferences where the description field of the announcement contains "graduate student" (case insensitive).
The first demo just uses a simple subject tag url.
https://mathmeetings.net/at-gt.json
The second demo uses a query string for the json interface. The query string format is the same as that of the search form (execpt for tags; see below).
https://mathmeetings.net/.json?description=graduate+student
The search query for tags uses a different syntax. Here is a more complex example that shows all conferences in the database after 01 January 2020 with subject tags any of ac, ag, or at, and description containing the word 'birthday'.
https://mathmeetings.net/.json?after=2020-01-01&tags[]=ac&tags[]=ag&tags[]=at&description=birthday
