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>
