el-input单独校验,效果图如下

复制代码

          <el-col :span="24">
            <el-form-item label="修订次数:" prop="sPublish">
              <el-input-number
                v-model="addForm.sPublish"
                :min="0"
                :controls="false"
                :precision="0"
                placeholder="请输入"
                @change="changesPublish"
                style="width: 80px"
                size="small"
              />
              -
              <el-input-number
                v-model="addForm.ePublish"
                :min="0"
                :controls="false"
                :precision="0"
                placeholder="请输入"
                style="width: 80px"
                size="small"
                @change="changesPublish"
              />
            </el-form-item>
          </el-col>

data中定义校验规则

复制代码

    saerchFormRules: {
        sPublish: [{ validator: this.validatePass, trigger: "blur" }],
      },

methods中使用

复制代码

 // 查询修订次数
    changesPublish(val) {
      this.$refs.addForm.validateField("sPublish");
    },

    validatePass(rule, value, callback) {
      if (this.addForm.sPublish > this.addForm.ePublish) {
        return callback(new Error("前数不能小于后数"));
      }
    },
