异步获取元素的脚本库 有问

```
async function selectPage() {

    const elmGetter = new ElementGetter();

    //let select = document.querySelectorAll("#root > div > div > div > div.weu-card.weu-card-bordered > div > div.page-ctn.fiex-footer > ul > div > div > div > div.weu-select-dropdown > ul.weu-select-dropdown-list");

    //let select50 = document.querySelector("#root > div > div > div > div.weu-card.weu-card-bordered > div > div.page-ctn.fiex-footer > ul > div > div > div > div.weu-select-dropdown > ul.weu-select-dropdown-list > li:nth-child(6)");

    //let isSelect = document.querySelector("#root > div > div > div > div.weu-card.weu-card-bordered > div > div.page-ctn.fiex-footer > ul > div > div > div > div.weu-select-selection > input");

    let = await elmGetter.get("#root > div > div > div > div.weu-card.weu-card-bordered > div > div.page-ctn.fiex-footer > ul > div > div > div > div.weu-select-dropdown > ul.weu-select-dropdown-list > li:nth-child(6)",
      "#root > div > div > div > div.weu-card.weu-card-bordered > div > div.page-ctn.fiex-footer > ul > div > div > div > div.weu-select-selection > input")

    if (isSelect.value != '50') {

      console.log(1);

      select50.click();

    }

}


```

报错：Uncaught (in promise) TypeError: parent.querySelector is not a function

是不是不接收这样的节点参数啊？

可以直接去库下面提问？

let = await elmGetter.get([
    "#root > div > div > div > div.weu-card.weu-card-bordered > div > div.page-ctn.fiex-footer > ul > div > div > div > div.weu-select-dropdown > ul.weu-select-dropdown-list > li:nth-child(6)",
    "#root > div > div > div > div.weu-card.weu-card-bordered > div > div.page-ctn.fiex-footer > ul > div > div > div > div.weu-select-selection > input"
]);
要得到元素数组，第一个参数必须是选择器数组，你漏了方括号。
