基于vue、react实现倒计时效果

<div id="example">
 <button @click="send">
 <span v-if="sendMsgDisabled">{{time+'秒后获取'}}</span>
 <span v-if="!sendMsgDisabled">send</span>
 </button>
</div>

var vm = new Vue({
 el: '#example',
 data() {
 return {
 time: 60, // 发送验证码倒计时
 sendMsgDisabled: false
 }
 },
 methods: {
 send() {
 let me = this;
 me.sendMsgDisabled = true;
 let interval = window.setInterval(function() {
 if ((me.time--) <= 0) {
 me.time = 60;
 me.sendMsgDisabled = false;
 window.clearInterval(interval); //停止
 }
 }, 1000);
 }
 }
 }) 

<button type="button" @click='delusercache()' :disabled="sendMsgDisabled" v-text="btnText"></button>
//倒计时按钮禁用:disabled="sendMsgDisabled

var vm = new Vue({
 el: '#example',
 data() {
 return {
 time: 60, // 发送验证码倒计时
 sendMsgDisabled: false //按钮可用
 }
 },
 methods: {
 time(){
 this.sendMsgDisabled= true; //按钮不可用
 let interval = window.setInterval(()=> {
 this.btnText = this.time + 's重新发送'
 if ((this.time--) <= 0) {
 this.time = 120;
 this.btnText ='发送验证码'
 this.sendMsgDisabled= false; //按钮可用
 window.clearInterval(interval);
 }
 }, 1000);
 }
 }) 

time = () => {
 this.setState({ 
 times: this.state.times-1,
 btnText: '' + this.state.times + 's重新发送)',
 // discodeBtn: false,
 clearInterval:true
 })
 var siv = setInterval(() => {
 this.setState({ 
 times: this.state.times-1,
 btnText: '' + this.state.times + 's重新发送)',
 // discodeBtn: false,
 clearInterval:true
 }, () => {
 if (this.state.times === 0) {
 clearInterval(siv);
 this.setState({ 
 times: 60,
 btnText: '发送验证码', 
 // discodeBtn: true,
 clearInterval:false,
 phone:false,
 isDisabled:false
 })
 }
 });
 }, 1000);
 };
<button 
className={(this.state.clearInterval ? 'send-btn-disabled-m' : 'send-btn-default')} 
disabled={this.state.isDisabled} 
onClick={this.getPhone} >
{this.state.btnText}
</button>
