There were tributes ahead of the match and Cardiff supporters passed a Thai flag with crests of both clubs into the away end.
Standing in black tracksuits the entire squad and backroom staff stood in a semi circle around the center circle, facing the matchday squad in its famous all-blue kit. It was always going to be an emotional day but I'm glad we got three points for him'.
In Thailand, Kiattisak Senamuang, a former Thai national soccer team coach and player, said: "It's a very hard time for his family and I'm here to show support. We wanted to do it for him and his family". Fans, mourners and players have all laid flowers at the site.
In the pre-match warmup the players wore white T-shirts bearing an image of Srivaddhanaprabha, below the words "the boss".

A Premier League referee has come under criticism for his decision to book Leicester City's Demari Gray for removing his jersey after scoring a goal for his side in today's clash against Cardiff City.
He said: 'You come across very few people in your life that hit you there and impact you.
Vichai, 60, founder of Thai duty-free giant King Power International, was killed last Saturday along with four others.
After the win, Leicester are set to fly to Bangkok to attend Srivaddhanaprabha's funeral following the match.
But the mood changed when referee Probert followed the letter of the law and booked Gray under a mandatory Federation Internationale de Football Association rule that says players must not remove their shirt over their head. The club's home ground has become a sprawling tribute of flowers, scarves and Leicester replica kits since last week's accident. In 2016, the club achieved the once-unthinkable feat of winning the premiership.
The club's extraordinary run of success played out under Srivaddhanaprabha's ownership. Srivaddhanaprabha's company sponsors the team's stadium.
Thousands of Leicester City fans have travelled to Wales for their match against Cardiff City - a game that is being seen as a tribute to their chairman, Vichai Srivaddhanaprabha who died in a hel.
