vue3按钮点击频率控制

现有一个按钮，如下图

点击时

再次点击

刷新窗口再次点击

刷新窗口依然可以实现点击频率控制。

代码实现：

<template><!--<el-config-provider :locale="locale"><router-view/></el-config-provider>--><el-button type="primary" @click="handleClick">click</el-button>
</template><script setup lang="ts">// @ts-ignoreimport zhCn from 'element-plus/dist/locale/zh-cn.mjs'import { reactive } from 'vue'import { ElMessage } from 'element-plus'// 国际化配置const locale = reactive(zhCn)const handleClick = () => {// 间隔为30sconst delay = 30000const key = 'ls_handle_click'let cache = getExpiredItem(key)if (cache <= 0) {setExpiredItem(key, Date.now(), delay)} else {const now = Date.now()const diff = delay / 1000 - (now - cache) / 1000ElMessage({showClose: true,message: `点击过于频繁,请${Math.floor(diff)}秒后尝试!`,type: 'warning',})return}// 执行按钮功能(处理业务逻辑)handleAlert()}// 封装可以设置过期时间的localStorageconst setExpiredItem = (key, value, expires) => {const data = {value: value,expires: Date.now() + expires}window.localStorage.setItem(key, JSON.stringify(data))}// 封装获取有过期时间的localStorage(我们规定如果key到期则返回-1，如果没有这个key就返回0)const getExpiredItem = (key) => {const value = window.localStorage.getItem(key)if (!value) {return 0}const data = JSON.parse(value)if (Date.now() > data.expires) {window.localStorage.removeItem(key)return -1}return data.value}// 按钮功能const handleAlert = () => {ElMessage({showClose: true,message: 'this is a success message.',type: 'success',})}
</script><style scoped lang="scss"></style>
