## Field 输入框
|
|
|
|
表单中`input`或`textarea`的输入框。
|
|
|
|
### 使用指南
|
|
``` javascript
|
|
import { Field } from 'vant';
|
|
|
|
Vue.component(Field.name, Field);
|
|
```
|
|
|
|
### 代码演示
|
|
|
|
#### 基础用法
|
|
通过 v-model 绑定输入框的值
|
|
|
|
:::demo 基础用法
|
|
```html
|
|
<van-cell-group>
|
|
<van-field v-model="value" placeholder="请输入用户名"></van-field>
|
|
</van-cell-group>
|
|
```
|
|
:::
|
|
|
|
#### 自定义类型
|
|
根据`type`属性定义不同类型的输入框
|
|
|
|
:::demo 自定义类型
|
|
```html
|
|
<van-cell-group>
|
|
<van-field
|
|
v-model="username"
|
|
label="用户名"
|
|
icon="clear"
|
|
placeholder="请输入用户名"
|
|
required
|
|
@click-icon="username = ''"
|
|
>
|
|
</van-field>
|
|
|
|
<van-field
|
|
v-model="password"
|
|
type="password"
|
|
label="密码"
|
|
placeholder="请输入密码"
|
|
required>
|
|
</van-field>
|
|
</van-cell-group>
|
|
```
|
|
:::
|
|
|
|
#### 禁用输入框
|
|
|
|
:::demo 禁用输入框
|
|
```html
|
|
<van-cell-group>
|
|
<van-field value="输入框已禁用" label="用户名" disabled></van-field>
|
|
</van-cell-group>
|
|
```
|
|
:::
|
|
|
|
#### 错误提示
|
|
|
|
:::demo 错误提示
|
|
```html
|
|
<van-cell-group>
|
|
<van-field label="用户名" placeholder="请输入用户名" error></van-field>
|
|
</van-cell-group>
|
|
```
|
|
:::
|
|
|
|
#### 高度自适应
|
|
对于 textarea，可以通过`autosize`属性设置高度自适应
|
|
|
|
:::demo 高度自适应
|
|
```html
|
|
<van-cell-group>
|
|
<van-field
|
|
v-model="message"
|
|
label="留言"
|
|
type="textarea"
|
|
placeholder="请输入留言"
|
|
rows="1"
|
|
autosize
|
|
>
|
|
</van-field>
|
|
</van-cell-group>
|
|
```
|
