vue2自定义组件阻止重复点击

1、插件一个自定义组件plugins.js

export default {
    install(Vue) {
        // 防重复点击(指令实现)
        Vue.directive('preventReClick', {
            inserted(el, binding) {
                el.addEventListener('click', () => {
                    if (!el.disabled) {
                        el.disabled = true
                        setTimeout(() => {
                            el.disabled = false
                        }, binding.value || 3000)
                    }
                })
            }
        })
    }
}

2、main.js中引入

import preventReClick from '@/assets/js/plugins.js'
Vue.use(preventReClick);

3、在vue项目中使用

<el-button @click="toSubmit('ruleForm')" v-preventReClick >提交</el-button>
