.replace(/(零)+/g, '零')
.replace(/零(万|亿|元)/g, '$1')
.replace(/(亿)万|(拾)/g, '$1$2')
.replace(/^元零?|零分/g, '')
.replace(/元$/g, '元') + '整'
}
this.form.taxNotIncludedCapital = ret
},@input事件：实时操作事件
过程：通过@input事件传入参数（123）到computeLen1方法中，通过一系列操作，最终拿到ref（壹佰贰拾叁元整），赋值到this.form.taxNotIncludedCapital
以上为个人经验，希望能给大家一个参考，也希望大家多多支持编程网。
