我希望你能帮到我，我正在尝试建立一个具有不同加权答案分数的问卷。这个想法是，当按下提交按钮时，将返回一个百分比分数。
我找到了一个在线教程，它给了我需要做什么的模板，在教程版本中检查了数组的每个值并将预定值添加到分数中，在我的场景中，我希望将数组中的相应值添加到分数中如果发现为真。
每个单选问答值都存储在一个数组中，
const auditCorrectAnswers = ['1', '20', '20', '20', '20', '20', '20', '20', '20', '20', '5', '5', '5', '10', '5', '5', '20', '20'];
当 if 语句为 true 时，我正在尝试从数组中提取值，该值位于forEach()循环正在检查的相同位置。
我以为已经设法使用以下语句来做到这一点
userAuditAnswers.forEach((auditAnswer, index) => {
if(auditAnswer === auditCorrectAnswers[index]){
auditScore += (auditCorrectAnswers, index);
}
});
console.log(auditScore);
但一起返回总索引位置值，因为它应该给出 256 的答案，但它是我得到的最接近解决方案的答案。
我已经尝试了valueOf()，values()和map()但这些都给出了数组中所有值的重复字符串。
我相信这很简单，但已经坚持了几天并且已经没有想法了，所以任何帮助将不胜感激。
这是我的代码：
const auditCorrectAnswers = ['1', '20', '20', '20', '20', '20', '20', '20', '20', '20', '5', '5', '5', '10', '5', '5', '20', '20'];
const form = document.querySelector('.venueAudit-form');
form.addEventListener('submit', e => {
e.preventDefault();
let auditScore = 0;
//takes the value from each radio button
const userAuditAnswers = [form.a1.value, form.a2.value, form.a3.value, form.a4.value, form.a5.value, form.a6.value, form.a7.value, form.a8.value, form.a9.value, form.a10.value, form.a11.value, form.a12.value, form.a13.value, form.a14.value, form.a15.value, form.a16.value, form.a17.value, form.a18.value];
// checks management audit scores
userAuditAnswers.forEach((auditAnswer, index) => {
if(auditAnswer === auditCorrectAnswers[index]){
auditScore += (auditCorrectAnswers, index);
}
});
console.log(auditScore);
});

如何制作一个对象数组？
item={correctAnswer:"some answer", points:someNumber}
然后：
var auditScore=0;
for(var answerIndex=0; answerIndex<userAuditAnswers.length; answerIndex++)
if(userAuditAnswers[answerIndex]==auditCorrectAnswers[index].correctAnswer)
auditScore+=auditCorrectAnswers[index].points;```
鉴于这些要求，在我看来，您想检查一个数组的总和与另一个数组的总和相比如何。
function arraySum(input) {
return input.reduce((sum, current) => sum + parseInt(current, 10), 0);
}
const auditCorrectAnswers = ['1', '20', '20', '20', '20', '20', '20', '20', '20', '20', '5', '5', '5', '10', '5', '5', '20', '20'];
const sumCorrectAnswers = arraySum(auditCorrectAnswers);
const userAuditAnswers = ['1', '20', '20', '20', '20', '20', '20', '20', '20', '20', '5', '5', '5', '10', '5', '5', '20', '20'];
const sumUserAnswers = arraySum(userAuditAnswers);
console.log(sumCorrectAnswers);
console.log(sumUserAnswers);
console.log(sumUserAnswers === sumCorrectAnswers);您声明的数组auditCorrectAnswers是一个">字符串"数组，因此您可以将其更改为数组 od 整数，然后更改此行
auditScore += (auditCorrectAnswers, index);
自
auditScore += auditCorrectAnswers[index];
我认为这行得通
