The display of togetherness came barely two months after Donovan criticized Beckham's leadership and commitment in a book about Beckham's stint with the Galaxy.
Donovan scored in the 21st minute, when Alan Gordon's shot ricocheted off Revolution defender Darius Barnes. Donovan volleyed the rebound from about 20 yards on the right that curled just inside the far post and past goalkeeper Matt Reis.
Jovan Kirovski's goal made it 2-0 in the 52nd minute, and Steve Ralston scored for the Revolution on a penalty kick in the 83rd.
The Galaxy, which had never won a regular-season game at Gillette Stadium before Saturday, improved to 5-0-1 in its last six games. In 2002, the Galaxy beat the Revolution, 1-0, at Gillette Stadium to win the MLS Cup.
On Donovan's goal -- his ninth of the season -- he kicked the ball out of the air with his left foot and, as it approached the net, Beckham, standing behind him, raised his arm as if anticipating a goal.
Then Donovan made his leap into Beckham's welcoming arms.
Immediately after Saturday's game, Beckham was scheduled to fly to England to train with the national team for an exhibition Wednesday night against the Netherlands in Amsterdam.
