今天想寫一個(gè)表單校驗(yàn)用戶有沒有填寫內(nèi)容

官方文檔是這樣寫的

<template>
    <i-form v-ref:form-validate :model="formValidate" :rules="ruleValidate" :label-width="80">

全部復(fù)制下來會(huì)發(fā)現(xiàn)根本沒有用

但是好在這個(gè)東西他開源

于是我去github上看了下源代碼

發(fā)現(xiàn)作者在源代碼中是這樣寫的

我也照葫蘆畫瓢 結(jié)果成功了

貼上代碼

<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'
                }]
            }
        }
    }
