How to Make Character Jump OnPress of Button

Hi guys please help me on this one. I am so noob in this actionscript programming
I am nowhere close to getting the codes right

I am making a runner, side scrolling game for a android phone. It is like World of Rabbit(WOR) or iRunner.
The character has a animation of running, What i want is the character will jump when i press the Jump Button. Then after that when it lands it will continue it's running animation. Also when it jumps it only goes up then land, it does not jump then land to other places, it only jump then land on it's exact position. Because the character is on the center of the screen.

Please help guys thanks in advance.
