meetup.com api login and search for upcoming events

We have a javascript that allows the user to load a file containing the “upcoming events” api output json from meetup.com api (attached) and it show the “upcoming events” and some properties of them, in a table, with an ajax search box.

We want to modify the page to allow the user to login to their meetup.com api account to perform searches for “upcoming events” filtering by city, radius and number of results. The results should be shown in the table as the example shows, so the user can sort the results by column. Double quotes in json should be scaped properly to avoid parsing errors.
