JS正确插入对象

Question

我正在尝试制作迷你口袋宠物小精灵游戏。这是我存储口袋妖怪的方式。

let Charmander = {
        "name": "Charmander",
        "type": "fire",
        "hp": "70",
        "weaknesses": ["ground", "rock", "water"],
    };
let Bulbasaur = {
        "name": "Bulbasaur",
        "type": ["Grass", "Poison"],
        "hp": "70",
        "weaknesses": ["Fire", "Flying", "Ice", "Psychic"],
    };
let Squirtle = {
        "name": "Squirtle",
        "type": "Water",
        "hp": "60",
        "weaknesses": ["Electric", "Grass"],
};

然后它会要求你选择你想要的起始口袋妖怪。

let startingChoice = prompt("What is your starting Pokemon " + Charmander.name + ", " + Bulbasaur.name + ", " + Squirtle.name);

然后我为第一个可以挑选的口袋妖怪创建一个数组

let firstPokemon = [ Charmander.name, Bulbasaur.name, Squirtle.name];

然后我会检查你输入的结果，看看它是否在里面。

if(startingChoice == "Charmander"){

    pokeBox.push(Charmander);

} else if(startingChoice == "Bulbasaur"){
    pokeBox.push(Bulbasaur);
}else{
    pokeBox.push(Squirtle);
}



}else{
    console.log("Chupa");
}

正如您在上面看到的那样，效率很低。我怎样才能做到这一点，以便当它放入您的 pokeBox 时，它会添加所有对象信息，而无需所有信息语句。

这是 pokeBox 的结果 Object { name: "Charmander", type: "fire", hp: "70", … } 我怎样才能使它更有效率？

Answer 1

你是如何偶然宣布 pokeBox 的？

    let starterKantoPokemon = [{
        "name": "Charmander",
        "type": "fire",
        "hp": "70",
        "weaknesses": ["ground", "rock", "water"],
    },
    {
        "name": "Bulbasaur",
        "type": ["Grass", "Poison"],
        "hp": "70",
        "weaknesses": ["Fire", "Flying", "Ice", "Psychic"],
    },
    {
        "name": "Squirtle",
        "type": "Water",
        "hp": "60",
        "weaknesses": ["Electric", "Grass"],
  }];
    let pokeBox = []; 

    let hasPokemonBeenChosen = false;
    while(!hasPokemonBeenChosen)
    {
        let startingChoice = prompt("What is your starting Pokemon\n 1. " + starterKantoPokemon[0].name + ", 2." + starterKantoPokemon[1].name + ", 3." + starterKantoPokemon[2].name);
       if(startingChoice >= 1 && startingChoice <=3) {
         pokeBox.push(starterKantoPokemon[startingChoice - 1]);
         hasPokemonBeenChosen = true;
       } 
}
console.log('Professor Oak: Hmm...' + pokeBox[0].name + '. Good choice!');

希望这会有所帮助。

    let pokeList = [{
        "name": "Charmander",
        "type": "fire",
        "hp": "70",
        "weaknesses": ["ground", "rock", "water"],
    }, {
        "name": "Bulbasaur",
        "type": ["Grass", "Poison"],
        "hp": "70",
        "weaknesses": ["Fire", "Flying", "Ice", "Psychic"],
    }, {
        "name": "Squirtle",
        "type": "Water",
        "hp": "60",
        "weaknesses": ["Electric", "Grass"],
}]
var name = "";
var pokeName = pokeList.filter((p)=>{
    name += p.name+", ";
})
let startingChoice = prompt("What is your starting Pokemon " + name.slice(0, -2));

var pokeBox = [];

pokeList.forEach(function(item, index){
    if(startingChoice == item.name){
        pokeBox.push(item)
    }
})

console.log(pokeBox)

关键是将所有的口袋妖怪放在自己的对象中。然后你可以用这样一种方式编码它，所有重要的是对象中的口袋妖怪，没有重复的名字或任何东西。在下面的示例中，您可以添加或删除您喜欢的任何口袋妖怪，它的工作方式相同。

const
  pokemon = {
       charmander: {
          "name": "Charmander",
          "type": "fire",
          "hp": "70",
          "weaknesses": ["ground", "rock", "water"],
      },
      bulbasaur: {
          "name": "Bulbasaur",
          "type": ["Grass", "Poison"],
          "hp": "70",
          "weaknesses": ["Fire", "Flying", "Ice", "Psychic"],
      },
      squirtle: {
          "name": "Squirtle",
          "type": "Water",
          "hp": "60",
          "weaknesses": ["Electric", "Grass"],
      },
  },
  pokeBox = [],
  promptString = `What is your starting pokemon?\n` +
    Object.values(pokemon)
    .map(p => p.name)
    .join(`, `),
  choice = prompt(promptString);
    
const lowerCaseChoice = choice.toLowerCase();
if (lowerCaseChoice in pokemon)
    pokeBox.push(pokemon[lowerCaseChoice]);
else
    console.log(`that is not a valid option`);

console.log(pokeBox)

希望这对你有用，这是一种有效的方法。

let starterPokemons = {
       charmander: {
          "name": "Charmander",
          "type": "fire",
          "hp": "70",
          "weaknesses": ["ground", "rock", "water"],
      },
      bulbasaur: {
          "name": "Bulbasaur",
          "type": ["Grass", "Poison"],
          "hp": "70",
          "weaknesses": ["Fire", "Flying", "Ice", "Psychic"],
      },
      squirtle: {
          "name": "Squirtle",
          "type": "Water",
          "hp": "60",
          "weaknesses": ["Electric", "Grass"],
      },
  };
let pokeBox = [];
let promptQuestion = 'What is your starting Pokemon\n';
Object.keys(starterPokemons).forEach(function(pokemon){
    promptQuestion += pokemon + ', ';
});

while(pokeBox.length == 0)
{
    let startingChoice = prompt(promptQuestion.slice(0, -2));
    startingChoice = startingChoice.toLowerCase();

    if(starterPokemons[startingChoice] == undefined){
        alert("Invalid Starter Pokemon");
    }
    else{
        pokeBox.push(starterPokemons[startingChoice]);
        alert("Congratulations you have selected " + starterPokemons[startingChoice].name + " as your Starter Pokemon");
    }
}
