After looking (Googling) on the web for a while, I can find nothing that takes an address like:
1200 Pennsylvania Ave SE, Washington, District of Columbia, 20003
and converts it into a clickable link:
jQuery or PHP preferred or just any useful information on this.
How about this?
https://maps.google.com/?q=1200 Pennsylvania Ave SE, Washington, District of Columbia, 20003
https://maps.google.com/?q=term
If you have lat-long then use below URL
https://maps.google.com/?ll=latitude,longitude
Example: maps.google.com/?ll=38.882147,-76.99017
UPDATE
As of year 2017, Google now has an official way to create cross-platform Google Maps URLs:
https://developers.google.com/maps/documentation/urls/guide
You can use links like
https://www.google.com/maps/search/?api=1&query=1200%20Pennsylvania%20Ave%20SE%2C%20Washington%2C%20District%20of%20Columbia%2C%2020003
