 最近在做一个Vue项目,前端通过手机号、验证码登录,获取验证码按钮需要设置60s倒计时(点击一次后,一分钟内不得再次点击)。先看一下效果图:

输入正确格式的手机号码后,“获取验证码”按钮方可点击;点击“获取验证码”后,按钮进入60s倒计时,效果图如下:

 效果图已经有了,接下来就上代码吧!

html <el-button @click="getCode()" :class="{'disabled-style':getCodeBtnDisable}" :disabled="getCodeBtnDisable">{{codeBtnWord}}</el-button> 数据data data() {      return {         loginForm: {             phoneNumber: '',             verificationCode: '',         },         codeBtnWord: '获取验证码', // 获取验证码按钮文字         waitTime:61, // 获取验证码按钮失效时间     } } 计算属性computed computed: {     // 用于校验手机号码格式是否正确     phoneNumberStyle(){         let reg = /^1[3456789]\d{9}$/         if(!reg.test(this.loginForm.phoneNumber)){             return false         }         return true     },     // 控制获取验证码按钮是否可点击     getCodeBtnDisable:{         get(){             if(this.waitTime == 61){                 if(this.loginForm.phoneNumber){                     return false                 }                 return true             }             return true         },         // 注意:因为计算属性本身没有set方法,不支持在方法中进行修改,而下面我要进行这个操作,所以需要手动添加         set(){}      } }

关于上面给计算属性添加set方法,可以参照//www.jb51.net/article/202496.htm

 css设置不可点击时置灰 .el-button.disabled-style {     background-color: #EEEEEE;     color: #CCCCCC; } mothods中添加获取验证码方法 getCode(){     if(this.phoneNumberStyle){         let params = {}         params.phone = this.loginForm.phoneNumber         // 调用获取短信验证码接口         axios.post('/sendMessage',params).then(res=>{             res = res.data             if(res.status==200) {                 this.$message({                     message: '验证码已发送,请稍候...',                     type: 'success',                     center:true                 })             }         })         // 因为下面用到了定时器,需要保存this指向         let that = this         that.waitTime--         that.getCodeBtnDisable = true         this.codeBtnWord = `${this.waitTime}s 后重新获取`         let timer = setInterval(function(){             if(that.waitTime>1){                 that.waitTime--                 that.codeBtnWord = `${that.waitTime}s 后重新获取`             }else{                 clearInterval(timer)                 that.codeBtnWord = '获取验证码'                 that.getCodeBtnDisable = false                 that.waitTime = 61             }         },1000)     } }

通过上面的代码,就可以实现了,如有错误,敬请指正!
