根据条件动态添加校验的问题

动态切换prop值时不能默认为空，不然校验会失效，可以用'empty'代替空值

<el-form label-width="95px" :model="form" ref="form" :rules="rules">
   <el-form-item label="总计星钻："  :prop="form.auditType===1?'score':'empty'">
      <el-input
        class="input"
        placeholder="请输入星钻"
        v-model.number="form.score"
      >
        <template slot="append">个</template>
      </el-input>
    </el-form-item>
    <el-form-item label="审核状态：" prop="auditType">
      <el-radio-group v-model="form.auditType" @change="change">
        <el-radio :label="1">通过</el-radio>
        <el-radio :label="2">不通过</el-radio>
      </el-radio-group>
    </el-form-item>
 </el-form>

<script>
export default {

  data() {
    return {
      form: {
        score: ''
      }
      rules: {
         score: [{ required: true, message: "请输星钻", trigger: "blur" }],
      }
    }
  },
  methods: {
    change(v) {
      if(v===2){
         this.$refs.form.clearValidate()
      }
    },
  }
}

</script>
