我正在尝试使用JSON文件构建一个表。 我想要的是一个表中列出了一些神奇宝贝(Pokémons列在JSON文件中)。我是.js eheh
的新手这是JSON文件(我只添加了两个pokémons):
{
"n001": {
"nome": "Bulbasaur",
"altrinomi": ["Fushigidane", "フシギダネ", "Bulbizarre", "Bisasam", "이상해씨"],
"numero": [80, null, null],
"genere": [87.5, 12.5],
"tipo": ["Erba", "Veleno"],
"classificazione": "Seme",
"altezza": "0.7m",
"peso": "6.9kg",
"cattura": 45,
"passiuova": 5120,
"abilità": ["Erbaiuto"],
"abilitànascosta": "Clorofilla",
"esperienza": 1059860,
"felicitàbase": 70,
"PAguadagnati": [0, 0, 0, 1, 0, 0],
"lottaaerea": false,
"gruppouova": ["Mostro", "Erba"],
"statsbase": [45, 49, 49, 45, 65, 65]
},
"n002": {
"nome": "Ivysaur",
"altrinomi": ["Fushigisou", "フシギソウ", "Herbizarre", "Bisaknosp", "이상해풀"],
"numero": [81, null, null],
"genere": [87.5, 12.5],
"tipo": ["Erba", "Veleno"],
"classificazione": "Seme",
"altezza": "1.0m",
"peso": "13.0kg",
"cattura": 45,
"passiuova": 5120,
"abilità": ["Erbaiuto"],
"abilitànascosta": "Clorofilla",
"esperienza": 1059860,
"felicitàbase": 70,
"PAguadagnati": [0, 1, 0, 0, 1, 0],
"lottaaerea": false,
"gruppouova": ["Mostro", "Erba"],
"statsbase": [60, 62, 63, 80, 80, 60]
}
}
这是带有javascript的html页面,用于构建内部表:

我尝试使用这种功能:https://sites.google.com/site/conciseexamples/javascript-examples/json-examples/json-to-table
我认为我所做的是:
有人能告诉我哪些是我的错误吗? XD 对不起这个问题,我知道只需要很多时间来阅读XD
提前致谢:D
答案 0 :(得分:3)
如果我理解正确,你想过滤掉没有中央卡洛斯号的小精灵,在中央卡洛斯号上对它们进行排序并显示它们?
var rows = document.createDocumentFragment();
Object.keys(pokemons).map(function (k) {
return pokemons[k];
}).filter(function (pokemon) {
return pokemon.numero[0] !== null;
}).sort(function (a, b) {
return a.numero[0] - b.numero[0];
}).forEach(function (pokemon, i) {
var tr = document.createElement('tr'),
indexCell = document.createElement('td'),
kalosCell = document.createElement('td'),
nameCell = document.createElement('td');
indexCell.innerHTML = ++i;
kalosCell.innerHTML = pokemon.numero[0];
nameCell.innerHTML = pokemon.nome;
[indexCell, kalosCell, nameCell].forEach(tr.appendChild.bind(tr));
rows.appendChild(tr);
});
document.querySelector('table > tbody').appendChild(rows);
或者创建单元格的方法略有不同:
var createTd = document.createElement.bind(document, 'td');
//...
.forEach(function (pokemon, i) {
var tr = document.createElement('tr');
[
[createTd(), ++i],
[createTd(), pokemon.numero[0]],
[createTd(), pokemon.nome]
].forEach(function (items) {
var td = items[0];
td.innerHTML = items[1];
tr.appendChild(td);
});
rows.appendChild(tr);
});
