我正在尝试查找用户输入的总价值。得到将数字与其相同值相乘的聚合

let Dem200 = document.querySelector(".input_200");
let output200 = document.querySelector(".result_200");
Dem200.addEventListener('blur', function() {
  let result200 = parseInt(Dem200.value) * 200;
  output200.innerHTML = result200;
})

let Dem100 = document.querySelector(".input_100");
let output100 = document.querySelector(".result_100");
Dem100.addEventListener('blur', function() {
  let result100 = parseInt(Dem100.value) * 100;
  output100.innerHTML = result100;
})

let Dem50 = document.querySelector(".input_50");
let Dem20 = document.querySelector(".input_20");
let Dem10 = document.querySelector(".input_10");
let Dem5 = document.querySelector(".input_5");
let Dem1 = document.querySelector(".input_1");

let output50 = document.querySelector(".result_50");
let output20 = document.querySelector(".result_20");
let output10 = document.querySelector(".result_10");
let output5 = document.querySelector(".result_5");
let output1 = document.querySelector(".result_1");

Dem50.addEventListener('blur', function() {
  let result50 = parseInt(Dem50.value) * 50;
  output50.innerHTML = result50;
})

Dem20.addEventListener('blur', function() {
  let result20 = parseInt(Dem20.value) * 20;
  output20.innerHTML = result20;
})

Dem10.addEventListener('blur', function() {
  let result10 = parseInt(Dem10.value) * 10;
  output10.innerHTML = result10;
})

Dem5.addEventListener('blur', function() {
  let result5 = parseInt(Dem5.value) * 5;
  output5.innerHTML = result5;
})

Dem1.addEventListener('blur', function() {
  let result1 = parseInt(Dem1.value) * 1;
  output1.innerHTML = result1;
})

window.onchange = function() {
  var inputs = document.getElementsByTagName('input'),
    resultinchancge = document.getElementById('total'),
    sum = 0;

  for (var i = 0; i < inputs.length; i++) {
    var ip = inputs[i];

    if (ip.name && ip.name.indexOf("total") < 0) {
      sum += parseInt(ip.value) || 0;
    }

  }

  resultinchancge.value = sum;
}
