2D - Change jump direction

Greetings everyone.

I’m trying to create a 2D platformer, and I wish to change the jump direction, when the player has rotated.
The rotation is working fine, but I cant make the player jump the x direction instead of the y direction.

Here is the code:

//Jump button
        if (Input.GetKeyDown(KeyCode.Space) && grounded) {
          GetComponent<Rigidbody2D>().velocity = new Vector2(GetComponent<Rigidbody2D>().velocity.x, jumpHeight);

   }

Thanks for taking your time reading this.

Jump the x direction? So like a dash?

Just switch the x and y values:

GetComponent<Rigidbody2D>().velocity = new Vector2(jumpHeight, GetComponent<Rigidbody2D>().velocity.y);
