    <el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px">
        <el-form-item label="" prop="age">
            <el-input v-model.number="ruleForm.age"></el-input>

    export default {
        data () {
            return {
                ruleForm: {
                    age: ""
                },
                rules: {
                    age: [
                        { required: false, message: "", trigger: "blur" },
                        { type: "number", message: "", trigger: "blur" },
                        { min: 1, max: 3, message: " 1  3 ", trigger: "blur" }
                    ]
                }
            };
        },
        methods: {
            submitForm (formName) {
                this.$refs[formName].validate((valid) => {
                    if (valid) {
                        alert("submit!");
                    } else {
                        console.log("error submit!!");
                        return false;
                    }
                });
            },
            resetForm (formName) {
                this.$refs[formName].resetFields();
            }
        }
    };
</script>

the result of the actual operation is: 1, when you do not enter anything, you will be prompted that "age must be a numeric value"; 2, after entering a number, you will be prompted "length is 1 to 3 characters", and the expected result is: 1, when you do not enter anything, no verification will be done; 2, enter 1-3 direct numbers, and the verification will pass;
