[值在计算中仅返回零

问题描述 投票：0回答：2

编辑：由于某种原因它现在正在工作，因为浏览器未使用.js文件进行更新，因此我必须使用atom-live服务器才能工作。

我正在尝试对网站进行多元智能测试。该测试将具有8种智力类型和每种智力类型上的5条陈述。我正在尝试获取每个选中按钮的值，以将其添加到它们的特定类型，但它只显示零。

这里是html的代码段（其他类型由于无法容纳而被删除）：

        var verbalScore = 0;
        var intrapersonalScore = 0;

        function calculateScores() {
          var button = document.getElementsByClassName("radiobutton");
          var buttonLength = button.length;
          musicalScore = 0;

          for (var i = 0; i < buttonLength; i++) {
            if (button[i].type === 'radio' && button[i].checked) {
              var value = Number(button[i].value);
              var type = button[i].getAttribute("personalityType");
              switch (type) {

                case "musical":
                  musicalScore += value;

它像魅力一样运作。您可以使用div或其他元素来打印结果。可以参考这个。刚刚将循环长度更新为buttonLength

var bodilyScore = 0;
   var mathematicalScore = 0;
   var naturalistScore = 0;
   var interpersonalScore = 0;
   var visualScore = 0;
   var verbalScore = 0;
   var intrapersonalScore = 0;

   function calculateScores() {
     var button = document.getElementsByClassName("radiobutton");
     var buttonLength = button.length;
     musicalScore = 0;
     bodilyScore = 0;
     mathematicalScore = 0;
     naturalistScore = 0;
     interpersonalScore = 0;
     visualScore = 0;
     verbalScore = 0;
     intrapersonalScore = 0;

     for (var i = 0; i < buttonLength; i++) {
       if (button[i].type === 'radio' && button[i].checked) {
         var value = Number(button[i].value);
         var type = button[i].getAttribute("personalityType");
         switch (type) {

           case "musical":
             musicalScore += value;
             break;

           case "bodily":
             bodilyScore += value;
             break;

           case "mathematical":
             mathematicalScore += value;
             break;

           case "naturalist":
             naturalistScore += value;
             break;

           case "interpersonal":
             interpersonalScore += value;
             break;

           case "visual":
             visualScore += value;
             break;

           case "verbal":
             verbalScore += value;
             break;

           case "intrapersonal":
             intrapersonalScore += value;
             break;
         }
       }
     }
     showResults();
   }
   
    function showResults() {
          console.log(musicalScore);
          console.log(bodilyScore);
          console.log(mathematicalScore);

          console.log(interpersonalScore); 
          console.log(visualScore); 
          console.log(verbalScore); 
          
          document.getElementById('musicalResult').innerText = musicalScore;
          document.getElementById('bodilyResult').innerText = bodilyScore;

我在您的JS中看到的唯一问题是radioButton.length。您将单选按钮的长度存储在buttonLength中，因此可以用radioButton.length代替buttonLength，它将起作用。

尝试运行此代码段

var bodilyScore = 0;
var mathematicalScore = 0;
var naturalistScore = 0;
var interpersonalScore = 0;
var visualScore = 0;
var verbalScore = 0;
var intrapersonalScore = 0;

function calculateScores() {
  debugger
  var button = document.getElementsByClassName("radiobutton");
  var buttonLength = button.length;
  musicalScore = 0;
  bodilyScore = 0;
  mathematicalScore = 0;
  naturalistScore = 0;
  interpersonalScore = 0;
  visualScore = 0;
  verbalScore = 0;
  intrapersonalScore = 0;

  for (var i = 0; i < buttonLength; i++) {
    if (button[i].type === 'radio' && button[i].checked) {
      var value = Number(button[i].value);
      var type = button[i].getAttribute("personalityType");
      debugger
      switch (type) {

        case "musical":
          musicalScore += value;
          break;

        case "bodily":
          bodilyScore += value;
          break;

        case "mathematical":
          mathematicalScore += value;
          break;

        case "naturalist":
          naturalistScore += value;
          break;

        case "interpersonal":
          interpersonalScore += value;
          break;

        case "visual":
          visualScore += value;
          break;

        case "verbal":
          verbalScore += value;
          break;

        case "intrapersonal":
          intrapersonalScore += value;
          break;
      }
    }
  }
  console.log('musicalScore', musicalScore)
  console.log('bodilyScore', bodilyScore)
  console.log('mathematicalScore', mathematicalScore)
  console.log('naturalistScore', naturalistScore)
  console.log('interpersonalScore', interpersonalScore)
  console.log('visualScore', visualScore)
  console.log('verbalScore', verbalScore)
  console.log('intrapersonalScore', intrapersonalScore)
}

function showResults() {
  document.getElementById('musicalResult').innerText = musicalScore;
  document.getElementById('bodilyResult').innerText = bodilyScore;
  document.getElementById('mathematicalResult').innerText = mathematicalScore;
  document.getElementById('naturalistResult').innerText = naturalistScore;
  document.getElementById('interpersonalResult').innerText = interpersonalScore;
  document.getElementById('visualResult').innerText = visualScore;
  document.getElementById('verbalResult').innerText = verbalScore;
  document.getElementById('intrapersonalResult').innerText = intrapersonalScore;
