Javascript 如果值位于数组中，则使用包含不起作用

我有两个阵列：

ids = [a,b,c,d,e,f....];

savedRepods = [e,f];

  function getPoints(){
      for (var i = 0; i < savedRepods.length; i++) {
        if(ids.includes(savedRepods[i]) ) {
          console.log(savedRepods[i]);
        }
      }
  }

---

可能是因为数组条目是

对象

类型<代码>数组.prototype.contains不适用于对象类型。因为在js中：

var a={
道具：“价值”
}
变量b={
道具：“价值”
}
如果（a！=b）{
log（'a不等于b'）；
}

检查重叠元素的代码工作正常。@但奇怪的是，我得到了

Uncaught（in promise）TypeError:无法读取未定义的

的属性'idValue'，但是当数组同时包含

e

和

f

时，它不包含

[e，f]

@PM77-1是的，这只是一个example@PM77-1代码在ids中检查数组savePods的元素。谢谢，但我认为比较很好，我必须有一些承诺。如果我有5个ID就可以了，但是如果我加上第6个ID就不行了。我删除了单身者ID只是为了检查他们是否有问题，但没有。所以，因为我没有任何类型的限制器，比如5或6，那么在承诺的情况下，5之后就会出现问题。我只是猜测，这让我快疯了。也许这

for（var I=0；I

给出了+1的承诺，这就是为什么跳过索引并产生问题的原因？@rob.m你能分享
