本文实例为大家分享了vue实现短信验证码输入框的具体代码，供大家参考，具体内容如下
先上最终效果 (此处代码显示的是短信验证码框的效果 其余部分并未放上去)
html
style="border-top-left-radius: 12px;
border-bottom-left-radius: 12px;"
type="text"/>
style="border-top-right-radius: 12px;
border-bottom-right-radius: 12px;
border-left:1px solid #c6c6c6;"
maxlength="1"
type="text"/>
js
data (){
return {
smsCode:'',
code:new Array(5),
codeId:['first','second','third','forth','fifth']
}
},
watch:{
code:function(newValue,oldValue){
console.log('newValue.length'+newValue.length)
let tempValue=''
for(let i=0;i
if(i==5){
console.log(i)
break
}
if(newValue[i]){
tempValue=tempValue+newValue[i]
}
}
this.smsCode=tempValue
console.log('smsCode '+this.smsCode)
let m=tempValue.split("")
let location=0
for(let i=0;i
if(m[i]&&i<5){
location++
newValue[i]=m[i]
}else{
newValue[i]=''
}
}
// console.log(this.codeId[i])
if(location<1){
location=1
}else if(location>5){
location=5
}
document.getElementById(this.codeId[location-1]).focus()
}
},
.inputStyle{
width:20%;
height:100%;
text-align:center;
border:none;
}
