js获取inpu焦点，输入完1位数字后自动跳到第二个光标

html代码块

<div class="mui-row" id="inputs">    <input class="mui-numbox-input" type="number" onKeyUp="if(this.value.length>1){this.value=this.value.substr(0,1)};this.value=this.value.replace(/[^\d]/g,'');"/>            <input class="mui-numbox-input" type="number" onKeyUp="if(this.value.length>1){this.value=this.value.substr(0,1)};this.value=this.value.replace(/[^\d]/g,'');"/>    <input class="mui-numbox-input" type="number" onKeyUp="if(this.value.length>1){this.value=this.value.substr(0,1)};this.value=this.value.replace(/[^\d]/g,'');"/>    <input class="mui-numbox-input" type="number" onKeyUp="if(this.value.length>1){this.value=this.value.substr(0,1)};this.value=this.value.replace(/[^\d]/g,'');"/>    <input class="mui-numbox-input" type="number" onKeyUp="if(this.value.length>1){this.value=this.value.substr(0,1)};this.value=this.value.replace(/[^\d]/g,'');"/>    <input class="mui-numbox-input" type="number" onKeyUp="if(this.value.length>1){this.value=this.value.substr(0,1)};this.value=this.value.replace(/[^\d]/g,'');"/></div>

css

#inputs{    overflow:hidden;}#inputs input{    width:14%;    float:left;    padding:10px 13px;    text-align: center;    border: 1px solid #fe8c10;    color: #fe8c10;    margin:0 1%;}

js代码

光标自动跳到下一个input        onload = function(){            var inputs=document.getElementById('inputs');            var txts = inputs.getElementsByTagName("input");            for(var i = 0; i<txts.length;i++){                var t = txts[i];                t.index = i;                t.setAttribute("readonly", true);                t.onkeyup=function(){                    this.value=this.value.replace(/^(.).*$/,'$1');                    var next = this.index + 1;                    if(next > txts.length - 1) return;                    txts[next].removeAttribute("readonly");                    txts[next].focus();                }            }            txts[0].removeAttribute("readonly");        }
