Question

我不知道为什么'test'段落在达到0时没有改变。我该怎么做？我试图将“损坏”，“愈合”放入“如果陈述”中，但是没有用。条件很简单，所以我不知道出了什么问题。

而且，当健康状况小于0或大于100时，如何停止功能？

minus.onclick = damage;
plus.onclick = heal;


if(health > 80){
    test.innerHTML = "Alive";
}else if(health <= 0){
    test.innerHTML = "Dead";
}

将if语句放入heal和Damage函数中。在功能之外，它们仅在文档加载时被调用一次。因此状态永远不会改变

let healthS = document.getElementById('health');
let plus = document.getElementById('plus');
let minus = document.getElementById('minus');

var health = 100;

let damage = () => {

  health -= Math.floor(Math.random() * 15);
  if(health<=0)
  {
  health=0;

  }
  healthS.innerHTML = "Enemy's health: " + health;
  
  if (health > 80) {
    test.innerHTML = "Alive";
  } else {
    test.innerHTML = "Dead";
  }
  
}

let heal = () => {
  health += Math.floor(Math.random() * 10);
  healthS.innerHTML = "Enemy's health: " + health;
  if (health > 80) {
    test.innerHTML = "Alive";
  } else {
    test.innerHTML = "Dead";
  }
}

minus.onclick = damage;
plus.onclick = heal;
if (health > 80) {
  test.innerHTML = "Alive";
} else {
  test.innerHTML = "Dead";
}

当运行状况达到0时，该段落不变
