vue2按钮防止重复提交指令

vue3参考：点击这里跳转

1、新建 preventReClick.js

import Vue from 'vue'

// 防止重复提交指令
const preventReClick = Vue.directive('preventReClick', {
    inserted (el, binding) {
        el.addEventListener('click', () => {
            if (!el.disabled) {
                el.disabled = true
                setTimeout(() => {
                    el.disabled = false
                }, binding.value || 3000)
            }
        })
    }
})

export { preventReClick }

2、main.js中使用

import { preventReClick } from './assets/js/preventReClick'

3、按钮上添加 v-prevent-re-click

<el-button size="small" type="primary" @click="submit" v-prevent-re-click>确 定</el-button>
