How to keep going forward while jumping ?

Hello, i’m trying so hard to make my character ( a cube ) keep going forward while jumping, but I just can’t find a solution. I tried to put my even out of the .isGround if condition, but still doesn’t work. Here is my code: ( sorry for the really bad organisation, i’m just trying to get part of codes from here and here, i’m learning from scratch )
using UnityEngine;
using System.Collections;

public class CubeMove : MonoBehaviour {

	public float speed = 7.0f;
	public float jumpSpeed = 6.0f;
	public float gravity = 5.0f;

	private Vector3 moveDirection = Vector3.zero;
	private CharacterController controller;


	// Use this for initialization
	void Start()
	{
		Cursor.visible = false;
		controller = GetComponent<CharacterController>();
	}

	// Update is called once per frame
	void Update()
	{

		if (controller.isGrounded) {

			if (Input.GetKey (KeyCode.Z)) {
				transform.Translate (Vector3.forward * 11 * Time.deltaTime);
			}

			if (Input.GetKey (KeyCode.S)) {
				transform.Translate (Vector3.back * 11 * Time.deltaTime);
			}

			if (Input.GetKey (KeyCode.Q)) {
				transform.Rotate (-Vector3.up * 160 * Time.deltaTime);
			}

			if (Input.GetKey (KeyCode.D)) {
				transform.Rotate (Vector3.up * 160 * Time.deltaTime);
			}
				
		} else {}

		if (Input.GetButton ("Jump")) {
			moveDirection = Vector3.up * jumpSpeed;	
		}

		moveDirection.y -= gravity * Time.deltaTime;
		controller.Move(moveDirection * Time.deltaTime);


	}
}

Instead of =, use +=

So, your jump line could look like: moveDirection += Vector3.up * jumpSpeed;
