vue防止多次点击，重复请求

1.添加自定义文件 preventReClick.js

import Vue from 'vue'

const preventReClick = Vue.directive('preventReClick', {
    inserted: function (el, binding) {
        el.addEventListener('click', () => {
            if (!el.disabled) {
                el.disabled = true
                setTimeout(() => {
                    el.disabled = false
                }, binding.value || 3000)
            }
        })
    }
});

export { preventReClick }

 

2.在main.js中引用

import preventReClick from './store/preventReClick' //防多次点击，重复提交

 

3.实现方式。在按钮上添加v-preventReClick

<el-button class="common-button" size="small" type="primary" @click="handleSave('form')" v-preventReClick>保 存</el-button>
