vue中如何防止用户频繁点击按钮详解

<el-button @click="clickBtn" :disable="isLock">按钮</el-button>
export default{
	data(){
		return {
			isLock: false, // 控制按钮的disable属性
		}
	},
	methods: {
		clickBtn(){
		 	// 设置按钮不可点击（disable: false）
			this.isLock = true
			// 执行耗时间的代码或事件请求等....
			
			// 等待事件执行完或者相应的间隔时间后，恢复按钮为可点击状态
			setTimeout(() => {
				this.isLock = false
			}, 2000)
		}
	}
}

====== directive.js文件中 ====
import Vue from 'vue'
const preventReClick = Vue.directive('preventReClick',{
	inserted: function(el, binding, vNode, oldVnode){
		el.addEventListener('click', () => {
			if(!el.disabled){
			    el.disabled = true
			    el.style.backgroundColor = '#ccc'
			    el.style.border = 'none'
       			setTimeout(() => {
          			el.disabled = false
          			 el.style.backgroundColor = '#1890ff'	
          			 el.style.border = '1px solid #1890ff'
        		}, 2000)
			}
		})
	}
})

export default {
	preventReClick 
}

====== 在main.js文件中引入指令 =====
import {preventReClick } from './directive/directive.js'
Vue.use(preventReClick )

	// 添加新属性
	<el-button type="primary" @click="handleSave" v-preventReClick>保存</el-button>

：click.once = 'orderEvaluste()'

<a href="js" rel="external nofollow"  id="" onClick="buttonSubmit()">按钮</a>
<script>
	function buttonSumbit(){
		document.getElementById('buttonId').onclick = null//解绑onclick事件
		alert('接下来要执行的内容')
}
</script>
