javascript - 复选框增减问题

问题描述

现在我面临一个问题，如果第一个复选框数量增加然后单击第二个复选框然后第一个复选框值将显示 1 它应该是我增加了 4 或 5 但它会自动显示 1 通过选中另一个复选框

我的 Js 代码在此代码中，我单击复选框，然后增加数字，但我还希望如果数字增加，则自动选中复选框。

function addRightAnswer(element, index) {
var getRadioInputNumber = document.querySelectorAll('.get-radio-input-number');
  if (element.checked) {
    getRadioInputNumber[index].value = 1;
  } else {
    getRadioInputNumber[index].value = 0;
  }         
}

function setCheckBox(element, index) {
var getRadioOptionsNumberCheck = document.querySelectorAll('.input-checkbox-correct');
  if (element.value > 0) {
    getRadioOptionsNumberCheck[index].checked = true;
  } else {
    getRadioOptionsNumberCheck[index].checked = false;
  }       
}
