Update() code:

        if (Input.GetKeyDown(KeyCode.Space)  isJumping == false  isFalling == false)
        {
            isJumping = true;
            viewScript.lockY = true;
            Jump();
        }

        if (isJumping == true  isFalling == false)
        {
            Jump();
        }

        if (isFalling == true  isJumping == false)
        {
            Fall();
        }

functions

public void Jump()
    {

        if (currJump < allowedJump)
        {
            float temp = 0.0f;
            temp = Mathf.Sin(Time.deltaTime) * jumpSpeed;
            currJump += temp;
            controller.Move(Vector3.up * temp * Time.deltaTime * jumpSpeed);
        }
        else
        {
            isJumping = false;
            isFalling = true;
        }
    }

    public void Fall()
    {
        if (isGrounded == false)
        {
            float temp = 0.0f;
            temp = Mathf.Sin(Time.deltaTime) * jumpSpeed;
            currJump -= temp;
            controller.Move(Vector3.up * temp * Time.deltaTime * jumpSpeed * -1);
        }
        else
        {
            isFalling = false;
            viewScript.lockY = false;
            currJump = 0;
        }
    }

what is a groundcheck

Groundcheck would be the ground that you are jumping from. Eg. If using a terrain, use that transfom as the position, it will be checking the Y (up) position.
