vue: 防止按钮重复点击

一、新建plugins.js

import Vue from 'vue'
// 在vue上挂载一个指量 preventReClick
const preventReClick = Vue.directive('preventReClick', {
    inserted: function (el, binding) {
        console.log(el.disabled)
        el.addEventListener('click', () => {
            if (!el.disabled) {
                el.disabled = true
                setTimeout(() => {
                    el.disabled = false
                }, binding.value || 3000)
                //binding.value可以自行设置。如果设置了则跟着设置的时间走
                //例如：v-preventReClick='500'
            }
        })
    }
});
export { preventReClick }

二、在main.js中引入

import preventReClick from './utils/plugins.js'

三、设置button重复点击

<Button v-if="isVerificate" type="primary" @click="getCode" v-preventReClick>获取验证码</Button>
