forEach 循环遍历对象并使用 document.write() 打印；

Question

有一个数组，由我需要循环遍历的几个对象组成（最好使用 forEach 循环，这是练习的范围）。我需要在屏幕上打印它们的详细信息（不能只在控制台上看到它们，这会更直接），并且最好有工具用 CSS 格式化它们。

我可以通过实际的 forEach 循环（见下文，try-1）更接近地打印 [object Object] 对的完整序列，而无法更深入地检索数据。

我已经设法打印出每个对象的详细信息（try-2），但只能通过手动调用的每个属性的繁琐列表。

有没有一种方法可以循环遍历对象并以有序的方式检索其数据并将其打印在屏幕上？提前致谢

var bulbasaur = { name: "Bulbasaur", height: 0.7, weight: 6.9, hatchSteps: 5100, types: ["Grass", " Poison"], eggGroups: ["Monster", " Grass"], abilities: ["Chlorophyll", " Overgrow"]};

var ivysaur = { name: "Ivysaur", height: 1, weight: 13, hatchSteps: 5100, types: ["Grass", " Poison"], eggGroups: ["Monster", " Grass"], abilities: ["Chlorophyll", " Overgrow"]};

var venusaur = { name: "Venusaur", height: 2, weight: 100, hatchSteps: 5100, types: ["Grass", " Poison"], eggGroups: ["Monster", " Grass"], abilities: ["Chlorophyll", " Overgrow"]};

var charmander = { name: "Charmander", height: 0.6, weight: 8.5, hatchSteps: 5100, types: ["Fire"], eggGroups: ["Monster", " Dragon"], abilities: ["Blaze", " Solar-power"]};

var charmeleon = { name: "Charmeleon", height: 1.1, weight: 19, hatchSteps: 5100, types: ["Fire"], eggGroups: ["Monster", " Dragon"], abilities: ["Blaze", " Solar-power"]};

var charizard = { name: "Charizard", height: 1.7, weight: 90.5, hatchSteps: 5100, types: ["Fire", " Flying"], eggGroups: ["Monster", " Dragon"], abilities: ["Blaze", " Solar-power"]};

var squirtle = { name: "Squirtle", height: 0.5, weight: 9, hatchSteps: 5100, types: ["Water"], eggGroups: ["Monster", " Water 1"], abilities: ["Rain-dish", " Torrent"]};

var wartortle = { name: "Wartortle", height: 1, weight: 22.5, hatchSteps: 5100, types: ["Water"], eggGroups: ["Monster", " Water 1"], abilities: ["Rain-dish", " Torrent"]};

var repository = [
  bulbasaur,
  ivysaur,
  venusaur,
  charmander,
  charmeleon,
  charizard,
  squirtle,
  wartortle
];


(try-1)

const keys = Object.entries(repository)

keys.forEach(function(item, key) {
  document.write(repository[key] + '<br>');
  document.write(item);
});```

try-2
```repository.forEach(function(pokemon){
  document.write('<p class="pokeTitle">' + pokemon.name + '</p>' +
                 'Height: ' + pokemon.height + '<br>' +
                 'Weight: ' + pokemon.weight + '<br>' +
                 'Hatch Steps: ' + pokemon.hatchSteps + '<br>' +
                 'Types: ' + pokemon.types + '<br>' +
                 'Egg Groups: ' + pokemon.eggGroups + '<br>' +
                 'Abilities: ' + pokemon.abilities + '<br>');
});```

(results using try-1)
[object Object]
0,[object Object][object Object]
1,[object Object][object Object]
2,[object Object][object Object]
3,[object Object][object Object]
4,[object Object][object Object]
5,[object Object][object Object]
6,[object Object][object Object]
7,[object Object]

(results using try-2)

查看实际数据的一种快速方法是使用JSON.stringify 将数据转换为字符串。

var bulbasaur = { name: "Bulbasaur", height: 0.7, weight: 6.9, hatchSteps: 5100, types: ["Grass", " Poison"], eggGroups: ["Monster", " Grass"], abilities: ["Chlorophyll", " Overgrow"]};
var ivysaur = { name: "Ivysaur", height: 1, weight: 13, hatchSteps: 5100, types: ["Grass", " Poison"], eggGroups: ["Monster", " Grass"], abilities: ["Chlorophyll", " Overgrow"]};
var venusaur = { name: "Venusaur", height: 2, weight: 100, hatchSteps: 5100, types: ["Grass", " Poison"], eggGroups: ["Monster", " Grass"], abilities: ["Chlorophyll", " Overgrow"]};
var charmander = { name: "Charmander", height: 0.6, weight: 8.5, hatchSteps: 5100, types: ["Fire"], eggGroups: ["Monster", " Dragon"], abilities: ["Blaze", " Solar-power"]};
var charmeleon = { name: "Charmeleon", height: 1.1, weight: 19, hatchSteps: 5100, types: ["Fire"], eggGroups: ["Monster", " Dragon"], abilities: ["Blaze", " Solar-power"]};
var charizard = { name: "Charizard", height: 1.7, weight: 90.5, hatchSteps: 5100, types: ["Fire", " Flying"], eggGroups: ["Monster", " Dragon"], abilities: ["Blaze", " Solar-power"]};
var squirtle = { name: "Squirtle", height: 0.5, weight: 9, hatchSteps: 5100, types: ["Water"], eggGroups: ["Monster", " Water 1"], abilities: ["Rain-dish", " Torrent"]};
var wartortle = { name: "Wartortle", height: 1, weight: 22.5, hatchSteps: 5100, types: ["Water"], eggGroups: ["Monster", " Water 1"], abilities: ["Rain-dish", " Torrent"]};

var repository = [
  bulbasaur,
  ivysaur,
  venusaur,
  charmander,
  charmeleon,
  charizard,
  squirtle,
  wartortle
];

document.querySelector('#repository').textContent = JSON.stringify(repository,null,2);

<pre id="repository"></pre>

不过，如果您想生成 HTML，只使用像 Mustache/Handlebars 这样的模板引擎可能会更简单/更强大
