今天想写一个表单校验用户有没有填写内容

官方文档是这样写的

<template>
    <i-form v-ref:form-validate :model="formValidate" :rules="ruleValidate" :label-width="80">
        <Form-item label="姓名" prop="name">
            <i-input :value.sync="formValidate.name" placeholder="请输入姓名"></i-input>
        </Form-item>
        <Form-item label="邮箱" prop="mail">
            <i-input :value.sync="formValidate.mail" placeholder="请输入邮箱"></i-input>
        </Form-item>
        <Form-item label="城市" prop="city">
            <i-select :model.sync="formValidate.city" placeholder="请选择所在地">
                <i-option value="beijing">北京市</i-option>
                <i-option value="shanghai">上海市</i-option>
                <i-option value="shenzhen">深圳市</i-option>
            </i-select>
        </Form-item>
        <Form-item label="选择日期">
            <Row>
                <i-col span="11">
                    <Form-item prop="date">
                        <Date-picker type="date" placeholder="选择日期" :value.sync="formValidate.date"></Date-picker>
                    </Form-item>
                </i-col>
                <i-col span="2" style="text-align: center">-</i-col>
                <i-col span="11">
                    <Form-item prop="time">

                    </Form-item>
                </i-col>
            </Row>
        </Form-item>
        <Form-item label="性别" prop="gender">

                    ],
                    gender: [

                    } else {                        this.$Message.error('表单验证失败!');
                    }
                })
            },
            handleReset (name) {                this.$refs[name].resetFields();
            }
        }
    }</script>

全部复制下来会发现根本没有用

但是好在这个东西他开源

于是我去github上看了下源代码

发现作者在源代码中是这样写的

我也照葫芦画瓢 结果成功了

贴上代码

<template>
    <div>
        <Row>
            <Form ref="formValidate1" :model="formValidate" :rules="ruleValidate" :label-width="80">
                <FormItem label="Name" prop="name">
                    <i-input v-model="formValidate.name" placeholder="Enter your name"></i-input>
                </FormItem>
            </Form>
        
        </Row>
    </div>
</template>
<script>
export default {
    data() {
        return {
            formValidate: {
            name: ''
            },
            ruleValidate: {
                name: [{
                required: true,
                message: 'The name cannot be empty',
                trigger: 'blur'
                }]
            }
        }
    }

}
</script>
<style scoped>

</style>
