VUE+elementUI实现表单发送验证码倒计时方法
1.HTML代码部分
<el-form-item label="输入验证码" prop="verificationCode">
<el-input v-model="accountSettingsForm.verificationCode" placeholder="请输入验证码" style="width: 84%"></el-input>
<el-button icon="el-icon-mobile-phone" @click="send" style="width: 15%" type="success" :disabled="disabled=!show" >
<span v-show="show">获取验证码</span>
<span v-show="!show" class="count">{{count}} s</span>
</el-button>
</el-form-item>
2.js代码部分
const TIME_COUNT = 60; //更改倒计时时间
data(){
return {
show: true, // 初始启用按钮
count: '', // 初始化次数
timer: null,
}
},
methods:{
send(){
if (!this.timer) {
this.count = TIME_COUNT;
this.show = false;
this.timer = setInterval(() => {
if (this.count > 0 && this.count <= TIME_COUNT) {
this.count--;
} else {
this.show = true;
clearInterval(this.timer); // 清除定时器
this.timer = null;
}
}, 1000)
}
}
}
