app.vue里添加如下代碼
<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>
