Vue 学习笔记 错误ResizeObserver loop completed with undelivered notifications

环境Vue3 Ts
使用了el-table 后，容易出现如下错误
ERROR
ResizeObserver loop completed with undelivered notifications.
at handleError (webpack-internal:///./node_modules/webpack-dev-server/client/overlay.js:299:58)
at eval (webpack-internal:///./node_modules/webpack-dev-server/client/overlay.js:318:7)

解决办法
在App.vue 下面加代码

const debounce = (callback: (...args: any[]) => void, delay: number) => {
      let tid: any;
      return function (...args: any[]) {
        const ctx = self;
        tid && clearTimeout(tid);
        tid = setTimeout(() => {
          callback.apply(ctx, args);
        }, delay);
      };
    };
 
    const _ = (window as any).ResizeObserver;
    (window as any).ResizeObserver = class ResizeObserver extends _ {
      constructor(callback: (...args: any[]) => void) {
        callback = debounce(callback, 20);
        super(callback);
      }
    };
  },复制

App.vue 完整代码如下：

<template>
  <div id="app">
    <router-view />
  </div>
</template>
<script lang="ts">
import { defineComponent } from "vue";
 
export default defineComponent({
  setup() {
    const debounce = (callback: (...args: any[]) => void, delay: number) => {
      let tid: any;
      return function (...args: any[]) {
        const ctx = self;
        tid && clearTimeout(tid);
        tid = setTimeout(() => {
          callback.apply(ctx, args);
        }, delay);
      };
    };
 
    const _ = (window as any).ResizeObserver;
    (window as any).ResizeObserver = class ResizeObserver extends _ {
      constructor(callback: (...args: any[]) => void) {
        callback = debounce(callback, 20);
        super(callback);
      }
    };
  },
});
</script>
<style lang="scss"></style>
 复制

为什么？？？ 我也不清楚原理
