vee-validate，正则校验规则怎么写？

Question

在vue项目中使用vee-validate的正则校验规则，后台返回tailZeroCount，然后动态生成正则表达式，如下：

 regexRule() {
    let tailZeroCount = this.warePublishData.warePublishVO.tailZeroCount ? this.warePublishData.warePublishVO.tailZeroCount : 3
    return /^[0-9]*[0]{`tailZeroCount`}$/
}

<input type="text" v-validate="{
       required: true,
       regex: regexRule
}"/>

但是打印出来的regexRule还是/^[0-9]*[0]{tailZeroCount}$/

Answer 1

let tailZeroCount = this.warePublishData.warePublishVO.tailZeroCount ? this.warePublishData.warePublishVO.tailZeroCount : 3
let regex = new RegExp("^[0-9]*[0]{" + tailZeroCount + "}$");
return regex
