Javascript 如何验证搜索中仅存在匹配的元素？

我知道标题不好，但很难用几句话来解释

我在夜视上实现了自动化，遇到了一些让我感到困惑的事情，因为我习惯于只为自动化而在JS上编码。通常，很容易验证元素是否存在。但是对于这一点，我有一个html元素来显示搜索结果，我需要验证结果是否只包含元素

因此，在本例中，我需要确保

实体结果

div上的所有

结果项

只有

提示值片段匹配

等于

-1000000.0

和

提示属性

等于

cpuLimit:

的结果

<div class="results" style="">
   <!----> 
   <div>
      <div class="results-set-title">Results</div>
      <!---->

下面我定义了isValid，它应用于传递给allValid的数组中的每个元素。此函数可在DOM更新后应用，您需要重新检查元素：

const isValid = elem => {
    const val = elem.getElementsByClassName('hint-val-fragment match')[0].innerHTML.trim()
    const hint = elem.getElementsByClassName('hint-prop')[0].innerHTML.trim()
    return (
        val === '-1000000.0'
        && hint === 'cpuLimit:'
    )
}
const allValid = arr => arr.every(isValid)


const parent = document.getElementsByClassName('entity-results')[0]
const children = Array.from(parent.children)


const allAreValid = allValid(children)

您想如何确保entity results div上的所有结果项都只有提示val fragment match等于-1000000.0且提示prop等于cpuLimit:。。。？代码测试？
