The 3-1 win ended the sequence of three games without a win or goal and the team did it in considerable style - certainly in the first 70 minutes - with two goals from Jermain Defoe and one from JJ himself before Charlton's solitary reply from Jerome Thomas.
"The lads were right at it and knew how important it was for us to get the win," explained JJ. "Especially in the first half, it was fast, furious and attacking football - I think that was what the fans were delighted with.
"We've got players here that want to play good football and, when we do, everyone is happy. I was obviously very happy with the way we were passing it around, we had Jermain running down the channels, Keano coming short and everything seemed to be clicking."
Given the goalless patch, JJ admitted there were a few nerves in the dressing room beforehand, but repeated his message over the need to stay calm as we approach the run-in.
"Everyone gets nerves before a game and we knew how big this one was for us.
"I think it helps, there is pressure all over the league at the moment and it just depends on how you handle it.
"You've got to just stay calm and continue to play football. We've got good footballers here who love to pass the ball around and we can pass teams off the park if we get going. It is important for us to maintain that.
"It is a very happy dressing room, we are all on a high, but we have got to maintain and continue it up at Sunderland next week."
Jermaine Jenas believes the gathering of three points against Charlton was vital to our ambitions of remaining in the top quarter of the Premiership table.
