动态改变校验项

html

:validate-on-rule-change="false"是否在 rules 属性改变后立即触发一次验证 默认是true，这里改为false即可 以下根据 is_ruku字段进行判断

 <el-form :model="drawer_data"  :rules="drawer_datarule"  :validate-on-rule-change="false"></el-form>

如果想针对其中一条进行正则特殊校验，则需要将校验代码作为函数写在methods内

js

methods:{
// 校验规则：正整数和0
valiaNumber(rule, value, callback) {
      if (this.drawer_data.is_ruku == "0") {
        if (validataNumber(value)) {
          callback();
        } else {
          callback(new Error("请输入纯数字格式"));
        }
      }
    }, 
},


  computed: {
    drawer_datarule() {
      return {
