我有一个带有 3 个选项卡的反应组件，每个选项卡都包含一个数据表，该数据表将根据活动选项卡填充 API 调用结果。所以每次都会有一个参数，我通过 API 调用传递并相应地显示数据。
这很好用，当我切换选项卡时，我正在获取数据，但是当我尝试从数据表中搜索然后单击另一个选项卡时，我收到错误为-
无法对未安装的组件执行 React 状态更新。这是一个空操作，但它表明您的应用程序中存在内存泄漏。要修复，请取消 componentWillUnmount 方法中的所有订阅和异步任务。
下面是我的示例代码：
组件.jsx
import React, { Component } from "react";
import axios from "axios";
class Details extends Component {
constructor() {
super();
this.state = {
data: [],
flag: 0
};
}
componentDidMount() {
const params = new FormData();
params.append("status", "upcoming");
axios.post("details/", params).then(res => {
if (res.data.result === 1) {
this.setState({ data: res.data.data, flag: 1 });
}
});
}
handleClick = event => {
const params = new FormData();
params.append("status", event.target.getAttribute("data-value"));
axios.post("details/", params).then(res => {
if (res.data.result === 1) {
this.setState({ data: res.data.data, flag: 1 });
}
});
};
render() {

我尝试使用 componentWillUnmount 进行更新，但没有解决。
我在 index.html 中初始化数据表。
那么可能的解决方案是什么。
