防止按钮多次点击 preventReClick

1. 创建 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 || 800)
            }
        })
    }
});

export { preventReClick }

2. 在main中引入

import '@/utils/preventReClick'

 

3. html文件中使用

<el-button type="primary" @click="foo" v-preventReClick>按钮</el-button>
