打字稿，"NodeListOf< Element>"不是数组类型或字符串类型 [英] Typescript,'NodeListOf<Element>' is not an array type or a string type

问题描述

将我的JS转换为TS严格模式.

Converting my JS to TS strict mode.

以下语法对我来说似乎不错，但TS在allSubMenus的for循环中抱怨:

The following syntax looks fine to me but TS is complaining in the for loop on allSubMenus with:

[ts] Type 'NodeListOf<Element>' is not an array type or a string type.

我想念什么?

function subAct(target:Node){

  const allSubMenus : NodeListOf<Element> = document.querySelectorAll('.subMenuItems') 

  for (const sub of allSubMenus){
    sub.classList.remove('active')
  }  
}

推荐答案

您需要将target编译器选项设置为es6或更高，以使NodeListOf<T>可以迭代.

You need to set the target compiler option to es6 or higher for NodeListOf<T> to be iterable.
