vue3 自定义防抖指令（全局）自定义指令增加

//代码路径 src\utils\throttle.js
// 点击防抖
const throttle = {bind: (el, binding) => {let throttleTime = binding.value // 防抖时间if (!throttleTime) { // 用户若不设置防抖时间，则默认1sthrottleTime = 1000}let timerlet disable = falseel.addEventListener('click', event => {if (timer) {clearTimeout(timer)}if (!disable) { // 第一次执行(一点击触发当前事件)disable = true} else {event && event.stopImmediatePropagation()}timer = setTimeout(() => {timer = nulldisable = false}, throttleTime)}, true)}}// 将函数作为默认导出
export default throttle

//代码位置 src\main.ts// 导入防抖逻辑js代码
import throttle from  '@/utils/throttle'const setupAll = async () => {const app = createApp(App)
// 全局注册指令
app.directive('throttle',throttle.bind)}//具体使用，效果是1.5秒内的连续点击都无效，不点了，等1.5秒后才生效
<el-button  type="danger" @click="getdocListF" v-throttle="1500">查询</el-button>
