For a JK flip-flop:
Q goes to 1 when J is 1 after the appropriate clock edge and stay there.
Q goes to 0 when K is 1 after the appropriate clock edge and stay there.
Q alternates its state when both J and K are 1 after the appropriate clock edge.
You need to know whether the FF changes state on the rising edge or the falling edge of the clock. Knowing that, you can then complete the table from what is stated above.
JK flip flop with J and K tied together is like a D type ff
If one of the inputs is tied to one of the outputs, i forget which, it behaves like a toggle flip flop.
Wiki is good on jk ff's

its jk flip flop with positive edge triggered flip flop
I know the function table of D flip flop when clock is raising the Q will be same as D input other wise no change
but what about JK flip flop
Look again at what I posted. It tells you want the JK FF does after the rising edge of the clock. By "stay there" I mean there's no change for further transitions of the clock.
