javascript - 我可以使用对象属性值作为 css 属性值吗？

Question

我有一个对象，其属性的值会反复变化。 除此之外，我还需要一个 css 属性的值来反射(reflect)对象的属性值。 下面是我的 javascript 函数，它将与其他东西一起执行......

const initStats = () => {
stats();



let uD = document.querySelector("#defense")
  let uSp= document.querySelector("#speed")
  let uSt = document.querySelector("#strength")
  let uHth = document.querySelector("#health")

  uD.textContent = "Defense: " + fighterUser.defense
  let width = fighterUser.defense
  const content = document.createElement('div');
  content.classList.add('content');
  content.style.width = fighterUser.defense
  uD.appendChild(content);


  uSp.textContent = "speed: " + fighterUser.speed
  uSt.textContent = "Strength: " + fighterUser.strength
  uHth.textContent = "health: " + fighterUser.health


  let cD = document.querySelector("#defense-cpu")
  let cSp= document.querySelector("#speed-cpu")
  let cSt = document.querySelector("#strength-cpu")
  let cHth = document.querySelector("#health-cpu")

  cD.textContent = "Defense: " + fighterCpu.defense
  cSp.textContent = "Speed: " + fighterCpu.speed
  cSt.textContent = "Strength: " + fighterCpu.strength
  cHth.textContent = "health: " + fighterCpu.health
}

这是我需要帮助的部分，我正在尝试做这样的事情，但我知道 css 不会将“fighterUser.defense”作为值...

uD.textContent = "Defense: " + fighterUser.defense
  let width = fighterUser.defense
  const content = document.createElement('div');
  content.classList.add('content');
  content.style.width = fighterUser.defense
  uD.appendChild(content);

谢谢大家!

可以在父节点上加一个'px'或者'%'，表示可以测量该值:

content.style.width = fighterUser.defense + 'px'
