我想为每个 oninput 的元素添加特定数量

Question

我制作了一个范围滑块，但我在输入时遇到问题我想以另一个数量添加特定数量，它应该在滑块的每个输入上增加数量。 我想在 2000 美元和 45000 美元中将按钮上的金额增加 150 美元，每当滑块范围接受输入时？ 如果有人可以帮助我实现它，如果可以的话，那将是一个很大的帮助！

 var range = document.getElementById("range"); var val = document.getElementById("value"); var vvv = document.getElementById("vvv"); var saved = document.getElementById("saved"); val.innerHTML = "$" + range.value + "K"; range.oninput = function() { val.innerHTML = "$" + this.value + "K"; }

Answer 1

let vvvMultiplier = .03
let savedMultiplier = .013
let template = (value) => {
  return `$${value}K`
}
range.oninput = function () {
  let value = Number(this.value)
  let inputValue = value
  let vvvValue = Math.floor(value * vvvMultiplier)
  let savedValue = Math.floor(value * savedMultiplier)
  let inputText = template(inputValue)
  let vvvText = template(vvvValue)
  let savedText = template(savedValue)
  val.innerHTML = inputText
  vvv.innnerHTML = vvvText
  saved.innerHTML = savedText
}
