本文实例为大家分享了基于vue、react实现倒计时效果的具体代码，供大家参考，具体内容如下

Vue

方案一：俩个元素

HTML：

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

JS：

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); } } })

方案二：一个元素，改变文字

HTML：

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

JS：

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); } })

React

引用块内容

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>
