我正在尝试编写一个以“弱点”作为输入的函数,并给出具有该弱点的所有口袋妖怪的名字。
考虑以下JSON:
访问https://raw.githubusercontent.com/Biuni/PokemonGO-Pokedex/master/pokedex.json
var pokemonWeakness = function(weaknessOfPokemon,allPokemon){
for( x in allPokemon){
if(weaknessOfPokemon==allPokemon[x].weaknesses){
console.log('pokemon with this weaknesses are: '+allPokemon[x].name)
}else{
null
}
}
}
var weaknessOfPokemon = prompt('enter the weaknesses of pokemon')
pokemonWeakness(weaknessOfPokemon,pokemonData.pokemon)
此功能的问题是不返回任何数据。
答案 0 :(得分:1)
weaknesses
数组Filter weaknessOfPokemon
是否为 includes小精灵。使用Array.map()
将名称提取到数组:
function findByPokemonWeakness(weaknessOfPokemon, pokemons){
return pokemons.filter((o) => o.weaknesses.includes(weaknessOfPokemon))
.map((o) => o.name);
}
fetch('https://raw.githubusercontent.com/Biuni/PokemonGO-Pokedex/master/pokedex.json')
.then(r => r.json())
.then(d => console.log(findByPokemonWeakness('Fire', d.pokemon)));

答案 1 :(得分:1)
由于您正在检查某个项目是否存在,因此您应该使用数组的includes()
。所以你的if
应该是:
if(allPokemon[x].weaknesses.includes(weaknessOfPokemon)){
您还应该return null;
中有else
。
尝试以下方式:
var pokemonData = {
"pokemon": [{
"id": 1,
"num": "001",
"name": "Bulbasaur",
"img": "http://www.serebii.net/pokemongo/pokemon/001.png",

"Grass",
"Poison"

"next_evolution": [{
"num": "002",

}, {
"num": "003",
"name": "Venusaur"
}]
}]
}
var pokemonWeakness = function(weaknessOfPokemon,allPokemon){
for( x in allPokemon){
if(allPokemon[x].weaknesses.includes(weaknessOfPokemon)){
return 'pokemon with this weaknesses are: '+allPokemon[x].name;
}else{
return null
}
}
}
var weaknessOfPokemon = prompt('enter the weaknesses of pokemon')
console.log(pokemonWeakness(weaknessOfPokemon,pokemonData.pokemon))
答案 2 :(得分:0)
正如您所包含的json所示,weaknesses
不是单个值,而是一个数组。我认为输入的是一个弱点,所以你应该做的,而不是检查是否相等,就是检查当前pokemen的weaknesses
数组是否包含来自输入的弱点。
我认为这个提示足以帮助用户,无论如何,以下更新都应该这样做。
...
if(allPokemon[x].weaknesses.indexOf(weaknessOfPokemon) > -1){
...

这里是一个简单的过滤器,每个解决方案只需将其包装在一个函数
上obj.pokemon.filter(x=>x.weaknesses.includes("Fire")).forEach(x=>console.log(x.name))
注意:从对象中剪切一些记录(发布字符限制)
