Javascript 反应错误：NotFoundError:未能执行'；removeChild'；在'；节点'；：要删除的节点不是此节点的子节点

我是新来的。当我使用search react应用程序时，我得到了如上所示的错误

用户列表 行动 从“./dispatcher/dispatcher”导入调度程序

我在这里使用的是通量反应程序。还包括通过jquery数据表显示的数据。

---

错误发生在我第一次搜索时，假设给username='something'，它在我的表中完美地显示出来。当我单击datatable列名或其附带的搜索时，问题就会出现，因为它会更改为我已经给出的伪数据。有时也会抛出上述错误。如果有人能提供帮助，那将是非常值得注意的。

当您：

使用

React

然后，使用外部脚本操作

React

呈现的DOM

现在，在下一个渲染周期（重新渲染）中，

React

找不到先前渲染的DOM节点，因为它已经被外部脚本修改/删除

我认为这段代码是罪魁祸首：

    $(document).ready(function() {
      $("#example").DataTable({
        ordering: true
      });
    });

有一篇很好的文章可以与

React

一起使用

jquerydatatable

。您可以参考它并尝试解决您的问题，也可以尝试用

React

版本的

DataTable

（例如：）替换它

---

注意：避免同时使用

React

和

JQuery

。从长远来看，这可能会产生问题。

有什么办法可以修改dom吗？您能详细说明一下吗？使用什么修改DOM？反应还是外部脚本？我收到了这个错误。我把代码移到了一个入口，全部修复了。谢天谢地，现在是2021年，请不要使用jQuery使用jQuery没有什么错，只要它能达到目的。
