Player Can Only Attack When Not Grounded

I want to make it so the player can only attack while in mid-air and is not grounded. So when you first tap, he only jumps, but when you are in mid-air, he will attack. I tried and tried to figure out but could never solve it.

Player Script

 using UnityEngine;
 using System.Collections;
 
 public class Player : MonoBehaviour {
 
     public float jumpPower = 555f;
 
     public bool grounded = false;
 
     private Rigidbody2D rb2d;
 
     private playerAttack player;
 
     void Start () 
     {
         rb2d = gameObject.GetComponent<Rigidbody2D>();
         anim = gameObject.GetComponent<Animator>();
         player = GameObject.Find("Player").GetComponent<playerAttack>();
 
     }
 
     void Update() 
     {
     
         anim.SetBool("Grounded",grounded);
         anim.SetFloat("Speed", Mathf.Abs(rb2d.velocity.x));
 
         if (Input.GetMouseButtonDown(0) && grounded)
         {
             rb2d.AddForce(Vector2.up * jumpPower);
         }
         
     }
 }

playerAttack Script

 using UnityEngine;
 using System.Collections;
 
 public class playerAttack : MonoBehaviour {
     
     private bool attacking = false;
 
     private float attackTimer = 0;
     private float attackCd = 0.125f;
     public bool grounded = true;
     
     public Collider2D attackTrigger;
     private Animator anim;
     private Player player;
     
     void Start()
     {
         player = GameObject.Find("Player").GetComponent<Player>();
     }
     void Awake()
     {
         anim = gameObject.GetComponent<Animator>();
         attackTrigger.enabled = false;
     }
     void Update()
     {
 
         if (Input.GetMouseButtonDown(0) && !attacking &&  // possibly another bool)
         {
             
             attacking = true;
             attackTimer = attackCd;
 
             attackTrigger.enabled = true;
             
         }
         
         if (attacking)
         {
             if(attackTimer > 0)
             {
                 attackTimer -= Time.deltaTime;
             }
             else
             {
                 attacking = false;
                 attackTrigger.enabled = false;
             }
             
         }
 
         anim.SetBool("Attacking", attacking);
         
     }
     
 }

Ground Check Script

 using UnityEngine;
 using System.Collections;
 
 public class GroundCheck : MonoBehaviour {
 
     private Player player;
 
     void Start()
     {
         player = gameObject.GetComponentInParent<Player>();
 
     }
     
     void OnTriggerEnter2D(Collider2D col)
     {
         player.grounded = true;
     }
 
     void OnTriggerStay2D(Collider2D col)
     {
         player.grounded = true;
     }
 
     void OnTriggerExit2D(Collider2D col)
     {
         player.grounded = false;
     }
     
 }
