You will use basically the same format for jumping as for firing a bullet, tracking the state of the jumping key. You will also need to retain the horizontal direction that the jump is initiated at: 
/** add the field */
private int jumpX; // to retain horizontal direction jumped

/** in jumping code (initiating a jump) */
// get horizontal direction of jump
jumpX = 0;
if (Greenfoot.isKeyDown("right")) jumpX++;
if (Greenfoot.isKeyDown("left")) jumpX--;
// set initial vertical speed
ySpeed = -15;
// initiate jump (leave ground)
setLocation(getX()+4*jumpX, ySpeed++);

/** in off ground code */
setLocation(getX()+4*jumpX, ySpeed++);
You can adjust the horizontal distance jumped by altering the 4's in the setLocation calls.
