如何删除嵌入在另一个 JSON 数组 (f7Contacts) 中的特定 JSON 数组 (consultas)，两者都保存在单个 localSorage 键中？

Question

我有一个存储为 JSON 数组的 localStorage 键 (f7Contacts)，它应该是。我知道如何使用localStorage.removeItem("myKey");.

正如您所看到的，我的数组由一组嵌入其中的 JSON 数组组成。有更广泛的一个名为f7Contacts和它里面有一些子阵列（以某种方式为它们命名）命名visitings和consultas。现在，我要删除的不是任何 JSON 数组中的单个项目，也不是整个f7Contacts数组，而是名为Consultas的 JSON 子数组。

我尝试了很多方法，但我无法获得有效的代码。

这是我到目前为止所得到的：

我的字符串化数组如下所示：

（现在我已经更新了字符串以使其更像我的真实案例，因为建议的答案设法删除了consultas其中一个联系人中的 ，并且在一种情况下它会consultas从第一个联系人中删除 并删除其余的联系人。我为您命名了 ELISA 和 FRANK 以区分它们。还更新了我的 Javascript 和 html 作为我自己的代码和 ????? 的答案之一的混合物。我这样做是为了保持我的环境一致。这段代码设法删除第一个联系人的咨询，但也删除其余的联系人。）：

HTML

<main>
<div class="results">
<h4>Consultas<span id="consultas"></span></h4>
</div>
<div class="control-buttons">
<div id="confirm" style="display: none">
<button id="delete">Delete</button>
<button id="dntdelete">Cancel</button>
</div>
<a onclick="clearConsults()">Delete Consultas</a><h3>SURE YOU WANT TO DELETE?</h3>
</div>
</main>
    

我必须明确指出，这个localStorage 键（f7Contacts）实际上是由应用程序中的另一个 js 存储的，如果我已经包含了localStorage.setItem("f7Contacts", JSON.stringify(contacts)); 在我上面代码的开头只是为了让你清楚。还要明确字符串中有几个联系人，任务是将consultas它们全部删除。
