Question

我希望获得有关此范围滑块以提供多个输出的帮助。我尝试了几种不同的方法，但似乎无法弄清楚。

如果数字达到千，我希望“ 590”文本为滑块值的5.9倍，带逗号。我希望“ 30,000”文本也应为滑块值的300倍，并且还要加上逗号

var elem = document.querySelector('input[type="range"]');

var rangeValue = function(){
  var newValue = elem.value;
  var target = document.querySelector('.value');
  target.innerHTML = newValue;
}

elem.addEventListener("input", rangeValue);

我在JavaScript中添加了几行。

当范围值更改时，您可以计算5.9 * newValue。基于this answer插入逗号I。使用parseInt()进行四舍五入，以避免出现诸如1003.0000000000001之类的怪异数字。

var elem = document.querySelector('input[type="range"]');

var rangeValue = function(){
  var newValue = elem.value;
  document.querySelector('.value').innerHTML = newValue;
  var perYear = insertCommas(5.9 * newValue);
  document.querySelector("#perYear").innerHTML = perYear;
  var perTwentyFive = insertCommas(300 * newValue);
  document.querySelector("#perTwentyFive").innerHTML = perTwentyFive;
}

elem.addEventListener("input", rangeValue);

function insertCommas(x) {
  return parseInt(x).toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
}
