使用 js 对象中的对象

  • 772

朋友们，我需要帮助来弄清楚如何使用多个对象，否则我会完全困惑，不明白做什么以及如何做。所以，我有一个对象：

let HERO = {
   name: '',
   age: 0,
   gender: 0,
}

还有另一个对象：

let PARTY = {
   qualyty: [],
   men: 0,
   woman: 0,
}

PARTY.qualyty[0] = HERO;

问题是，如何才能在将PARTY.qualyty对象添加到数组时，根据对象的属性自动计算HERO参数？我创建了一个执行计算的函数，但我不知道将它放在哪里，以便它在向数组添加新元素时自动工作并重新计算：PARTY.manPARTY.womangenderHERO

function Counter() {
      var result = 0;
      for (var i = 0; i < PARTY.qualyty.length; i++) {
        if (PARTY.qualyty[i].gender == 1) {
          result = result + 1;
        }
        return result;
      }

如何实施？这样您就不必在每次添加新对象时都调用该 HERO函数PARTY.qualyty？

考虑到您的提示和澄清，我提出了以下目标：

let PEOPLE = {
    gender: 0,
    fraction: 0,
    race: 0,
    age: 0,
    socialStats: 0,
    work: 0,
};

let CASTLE = {
  social: {
    peopleTotal: [],
    freeMen: 0,
    freeFemale: 0,
    slaveMen: 0,
    slaveFemale: 0,
    children: 0,
    happy: 100,
    addPeople(people) {
      console.log('people', people);
      if (CASTLE.social.peopleTotal.length > 0) {
        for (var i = 0; i < CASTLE.social.peopleTotal.length; i++) {
          if (people.gender == 0 && people.socialStats == 1) {
            CASTLE.social.freeMen += 1;
          } else if (people.gender == 0 && people.socialStats == 0) {
            CASTLE.social.slaveMen += 1;
          } else if (people.gender == 1 && people.socialStats == 1) {
            CASTLE.social.freeFemale += 1;
          } else if (people.gender == 1 && people.socialStats == 0) {
            CASTLE.social.slaveFemale += 1;
          }
        }
      }

    }
  },
  laws: {
    taxes: 0,
    slavery: 0,
    drinking: 0,
  }
};

但是，当我尝试将 PEOPLE 对象分配给 CASTLE.social.peopleTotal 数组的零元素时，相应的计数器不会更新，也就是说，该函数要么根本不起作用，要么起作用，但不正确：

function getRandom(min, max) {
  min = Math.ceil(min);
  max = Math.floor(max);
  return Math.floor(Math.random() * (max - min + 1)) + min; //Максимум и минимум включаются
}

CASTLE.social.peopleTotal[0] = Object.assign({}, PEOPLE, { gender: getRandom(0, 1), fraction: getRandom(0, 6), race: getRandom(0, 4), age: getRandom(5, 60), socialStats: getRandom(0, 1), work: 0})
console.log('human: ', CASTLE.social.peopleTotal[0]);
console.log('free male: ', CASTLE.social.freeMen);
console.log('free female: ', CASTLE.social.freeFemale);
console.log('slave man: ', CASTLE.social.slaveMen);
console.log('slave female: ', CASTLE.social.slaveFemale);

    在问题的示例中，对象仅存储数据。因此，您需要自己更新所有字段

    PARTY.qualyty[0] = HERO;
if (HERO.gender == 0){
    PARTY.men += 1;
}else{
    PARTY.woman += 1;
}

    为了不每次都写这个，把这段代码传给PARTY对象方法就够了

    let PARTY = {
   qualyty: [],
   men: 0,
   woman: 0,
   addQualyty(){
      PARTY.qualyty[0] = HERO;
      if (HERO.gender == 0){
          PARTY.men += 1;
      }else{
          PARTY.woman += 1;
      }       
   }
}

    为了使其更加通用，您需要将要添加的对象添加到参数中，并将对 PARTY 对象的引用替换为this：

    addQualyty(hero){
   this.qualyty.push(hero);
   if (hero.gender == 0){
       this.men += 1;
   }else{
       this.woman += 1;
   }       
}
