等用户输入的组件。 使用表单,您可以收集、验证和提交数据。
典型表单
最基础的表单包括各种输入表单项,比如input、select、radio、checkbox等。
在每一个 form 组件中,你需要一个 form-item 字段作为输入项的容器,用于获取值与验证值。
form value:
{ "email": "", "password": "", "confirmPwd": "", "agreement": false, "zone": "" }
<script setup>

import {reactive, ref} from 'vue'
import Form from '@/components/Form/Form.vue'
import FormItem from '@/components/Form/FormItem.vue'
import Input from '@/components/Input/Input.vue'
import Button from '@/components/Button/Button.vue'
import Switch from '@/components/Switch/Switch.vue'
import Select from '@/components/Select/Select.vue'
const model = reactive({
email: '',
password: '',
confirmPwd: '',
agreement: false,
zone: ''
})
const options = [
{label: 'zone 1', value: 'one'},
{label: 'zone 2', value: 'two'},
{label: 'zone 3', value: 'three'}
]
const formRef = ref()
const submit = async () => {
alert('submitted!')
}
const reset = () => {
formRef.value.resetFields()
}
</script>
<template>
<div>
<Form :model="model" ref="formRef">
<!-- <FormItem prop="name" label="enter your name" #default="{ validate }">
<input v-model="model.name" @blur="validate('blur')" @input="validate('input')"/>
</FormItem> -->
<FormItem prop="email" label="the email">
<Input v-model="model.email"/>
</FormItem>
<FormItem prop="password" label="the password">
<Input v-model="model.password" type="password"/>
</FormItem>
<FormItem prop="agreement" label="agreement">
<Switch v-model="model.agreement"/>
</FormItem>
<FormItem prop="zone" label="zone">
<Select v-model="model.zone" :options="options"/>
</FormItem>
<FormItem>
<Button @click.prevent="submit" type="primary">Submit</Button>
<Button @click.prevent="reset">Reset</Button>
</FormItem>
</Form>
<p>
form value:
<pre>{{ model }}</pre>
</p>
</div>
</template>

表单校验
Form 组件允许你验证用户的输入是否符合规范,来帮助你找到和纠正错误。
Form 组件提供了表单验证的功能,只需为 rules 属性传入约定的验证规则,并将 form-Item 的 prop 属性设置为需要验证的特殊键值即可。 更多高级用法可参考 async-validator。
