如何编写将嵌套对象分配给父对象属性的函数？

Question

I want to write an equipWeapon function runs, when an HTML image is clicked, which reassigns the weapon property of the object to the first element of the inventory array.

HTML:

<img src="bag.png" id="bag" onclick="equipWeapon()">

JS:

const player1= { 
  name: "Bob",
  inventory: [ { type: 'mace', damage: 5 } ],
  health: 10,
  weapon: { 
      type: 'baseball bat',
      damage: 2
       }
};

function equipWeapon2(h) {
    if (h.inventory.length > 0) {
        h.weapon= h.inventory[0]
    } else {

    }
}

function equipWeapon() {
    equipWeapon2(player1);
}

Answer 1

This function will switch the current player's weapon property with the weapon in position 0 at the inventory array.

function equipWeapon2(h) {
    if (h.inventory.length > 0) {
        let oldWeapon = h.weapon;
        h.weapon= h.inventory[0]
        h.inventory[0] = oldWeapon;
    } else {

    }
}
