vue3实现防抖、单页面引入、全局引入、全局挂载

---

代码实现

const debounce = (fn: any, delay: number) => {
    let timer: any = undefined;

    return (item: any) => {
        if (timer) clearTimeout(timer);

        timer = setTimeout(() => fn(item), delay);
    }
};

export default debounce;

---

单页面引入

// 防抖(单页面引用)
import debounce from '../../../utils/debounce';

---

全局引入

main.ts

import App from './App.vue';
import debounce from './utils/debounce';

const app = createApp(App);
app.config.globalProperties.$debounce = debounce;

---

使用

html

<el-slider v-model="sliderValue" size="small" show-input @input="handleScheduleInput" />

---

单页面使用

let handleScheduleInput = debounce((val: number) => {
    console.log('滑块: ', val);
}, 1000 * 1);

---

全局使用

// 防抖(全局挂载)
let self = getCurrentInstance()?.appContext.config.globalProperties;

let handleScheduleInput = self?.$debounce((val: number) => {
    console.log('滑块: ', val);
}, 2000 * 1);
