在JS中从API获取数据

Question

我最近一直在为我玩的一款游戏开发boxrater，我遇到了一个小问题。该函数从myTextarea获取用户输入值，然后将其拆分成一个数组。然后，该函数获取带有用户输入的api，如果成功，则将评级添加到小计类别(例如:黄金)。循环完成后，将为用户显示所有类别的值。

由于某些原因，合计和小计类别的输出总是具有不同的值。只有当用户输入很大时，才会发生这种情况。

Input that causes different outputs Output1 Output2

同样，这些输出完全是随机的，只是示例。有时它甚至输出正确的量，但很少见。

function boxRater() {
    var x = document.getElementById("myTextarea").value.split(/\n|-|Level|:| |,/);
    var helper = {
        total: "Total: ",
        shadow: 0,
        cursed: 0,
        rainbow: 0,
        glitter: 0,
        golden: 0,
        luminous: 0,
        amount: 0
    };
    var doNothing = {
        total: "Total: ",
        amount: 0
    };

    url = 'https://pokemoncreed.net/ajax/pokedex.php?pokemon='

    for (var i = 0; i <= x.length; i++) {
        fetch(url + x[i])
            .then((res) => res.json())
            .then((data) => {
                console.log(data.rating);
                if (data.success === false) {
                    console.log("error");
                    console.error(err);
                }
                if (data.name.includes("Golden")) {
                    if (data.rating.includes("m")) {
                        doNothing.amount = parseFloat(data.rating) * 1000000;
                        helper.golden = doNothing.amount + helper.golden;
                    }
                    if (data.rating.includes("k")) {
                        doNothing.amount = parseFloat(data.rating) * 1000;
                        helper.golden = doNothing.amount + helper.golden;
                    }
                }
                if (data.name.includes("Rainbow")) {
                    if (data.rating.includes("m")) {
                        doNothing.amount = parseFloat(data.rating) * 1000000;
                        helper.rainbow = doNothing.amount + helper.rainbow;
                    }
                    if (data.rating.includes("k")) {
                        doNothing.amount = parseFloat(data.rating) * 1000;
                        helper.rainbow = doNothing.amount + helper.rainbow;
                    }
                }
                if (data.name.includes("Shadow")) {
                    if (data.rating.includes("m")) {
                        doNothing.amount = parseFloat(data.rating) * 1000000;
                        helper.shadow = doNothing.amount + helper.shadow;
                    }
                    if (data.rating.includes("k")) {
                        doNothing.amount = parseFloat(data.rating) * 1000;
                        helper.shadow = doNothing.amount + helper.shadow;
                    }
                }
                if (data.name.includes("Luminous")) {
                    if (data.rating.includes("m")) {
                        doNothing.amount = parseFloat(data.rating) * 1000000;
                        helper.luminous = doNothing.amount + helper.luminous;
                    }
                    if (data.rating.includes("k")) {
                        doNothing.amount = parseFloat(data.rating) * 1000;
                        helper.luminous = doNothing.amount + helper.luminous;
                    }
                }
                if (data.name.includes("Cursed")) {
                    if (data.rating.includes("m")) {
                        doNothing.amount = parseFloat(data.rating) * 1000000;
                        helper.cursed = doNothing.amount + helper.cursed;
                    }
                    if (data.rating.includes("k")) {
                        doNothing.amount = parseFloat(data.rating) * 1000;
                        helper.cursed = doNothing.amount + helper.cursed;
                    }
                }
                if (data.name.includes("Glitter")) {
                    if (data.rating.includes("m")) {
                        doNothing.amount = parseFloat(data.rating) * 1000000;
                        helper.glitter = doNothing.amount + helper.glitter;
                    }
                    if (data.rating.includes("k")) {
                        doNothing.amount = parseFloat(data.rating) * 1000;
                        helper.glitter = doNothing.amount + helper.glitter;
                    }
                }

                helper.amount = helper.cursed + helper.rainbow + helper.golden + helper.luminous + helper.shadow + helper.glitter;
                document.getElementById("testing").innerHTML = x;

                document.getElementById("golden").innerHTML = helper.golden;
                document.getElementById("rainbow").innerHTML = helper.rainbow;
                document.getElementById("shadow").innerHTML = helper.shadow;
                document.getElementById("cursed").innerHTML = helper.cursed;
                document.getElementById("glitter").innerHTML = helper.glitter;
                document.getElementById("luminous").innerHTML = helper.luminous;
                document.getElementById("total").innerHTML = helper.amount;
            })
    }
}

下面的代码是我一直在测试它的html页面。同样，myTextarea中给出的这些示例也是有效的，但给出了一个更长的列表，如屏幕截图中所示。

如果有人知道如何解决这个问题，请给我解释一下。该评分器适用于个别情况，但我需要它的工作，为大型用户输入。~节日快乐！

多亏了Jaromanda X注释，我能够修复我的代码。问题是因为它不是异步函数，所以我调整了代码，使其与异步函数一起工作。

function boxRater(){
var x = document.getElementById("myTextarea").value.split(/\n|-|Level|:| |5|,/);
return x;
}
url = 'https://pokemoncreed.net/ajax/pokedex.php?pokemon='
async function totalC () {
const x = boxRater();
console.log(x);
let helper = {total: "Total: ", shadow:0, cursed:0, rainbow:0, glitter:0,
golden:0,luminous:0, amount:0};
let doNothing = {total: "Total: ", amount:0};

for(let i =0; i <= x.length; i++){
let response = await fetch (url+x[i])
        let data = response.json()
        .then((data) => {
            console.log(data.rating);
        if(data.success === false){
    throw new SyntaxError("Error");
 }
if(data.success === true){

  if(data.name.includes("Golden")){
    if (data.rating.includes("m")){
      doNothing.amount = parseFloat(data.rating) * 1000000;
      helper.golden = doNothing.amount + helper.golden;
    }
    if (data.rating.includes("k")){
      doNothing.amount = parseFloat(data.rating) * 1000;
      helper.golden = doNothing.amount + helper.golden;
    }
}
if(data.name.includes("Rainbow")){
  if (data.rating.includes("m")){
      doNothing.amount = parseFloat(data.rating) * 1000000;
      helper.rainbow = doNothing.amount + helper.rainbow;
  }
  if (data.rating.includes("k")){
      doNothing.amount = parseFloat(data.rating) * 1000;
      helper.rainbow = doNothing.amount + helper.rainbow;
  }
}
if(data.name.includes("Shadow")){
  if (data.rating.includes("m")){
      doNothing.amount = parseFloat(data.rating) * 1000000;
      helper.shadow = doNothing.amount + helper.shadow;
  }
  if (data.rating.includes("k")){
     doNothing.amount = parseFloat(data.rating) * 1000;
      helper.shadow = doNothing.amount + helper.shadow;
  }
}
if(data.name.includes("Luminous")){
  if (data.rating.includes("m")){
      doNothing.amount = parseFloat(data.rating) * 1000000;
      helper.luminous = doNothing.amount + helper.luminous;
  }
  if (data.rating.includes("k")){
      doNothing.amount = parseFloat(data.rating) * 1000;
      helper.luminous = doNothing.amount + helper.luminous;
  }
}
if(data.name.includes("Cursed")){
    if (data.rating.includes("m")){
      doNothing.amount = parseFloat(data.rating) * 1000000;
      helper.cursed = doNothing.amount + helper.cursed;
    }
    if (data.rating.includes("k")){
      doNothing.amount = parseFloat(data.rating)*1000;
      helper.cursed = doNothing.amount + helper.cursed;
    }
}
if(data.name.includes("Glitter")){
  if (data.rating.includes("m")){
   doNothing.amount = parseFloat(data.rating) * 1000000;
      helper.glitter = doNothing.amount + helper.glitter;
  }
  if (data.rating.includes("k")){
      doNothing.amount = parseFloat(data.rating) * 1000;
      helper.glitter = doNothing.amount + helper.glitter;
  }
}
if (data.rating.includes("Not rated")){
    console.log("Not rated");
}
} 
helper.amount = helper.cursed+helper.rainbow+helper.golden+helper.luminous+helper.shadow+helper.glitter;
document.getElementById("golden").innerHTML = helper.golden;
document.getElementById("rainbow").innerHTML = helper.rainbow;
document.getElementById("shadow").innerHTML = helper.shadow;
document.getElementById("cursed").innerHTML = helper.cursed;
document.getElementById("glitter").innerHTML = helper.glitter;
document.getElementById("luminous").innerHTML = helper.luminous;
document.getElementById("cost").innerHTML = helper.amount ;
        })

}

}
