## Form
|
||
|
|
|
||
|
|
Form consiste en `input`, `radio`, `select`, `checkbox`, etcétera. Con el formulario, usted puede recopilar, verificar y enviar datos.
|
||
|
|
|
||
|
|
### Form básico
|
||
|
|
|
||
|
|
Incluye todo tipo de entradas, tales como `input`, `select`, `radio` y `checkbox`.
|
||
|
|
|
||
|
|
:::demo En cada componente `form`, necesita un campo `form-item` para que sea el contenedor del ítem.
|
||
|
|
|
||
|
|
```html
|
||
|
|
<el-form ref="form" :model="form" label-width="120px">

||
|
|

:::
|
||
|
|
|
||
|
|
:::tip
|
||
|
|
[W3C](https://www.w3.org/MarkUp/html-spec/html-spec_8.html#SEC8.2) reglamenta que
|
||
|
|
|
||
|
|
> <i>Cuando sólo hay un campo de entrada de texto de una sola línea en un formulario, el agente usuario debe aceptar <b>Enter</b> en ese campo como una solicitud para enviar el formulario.</i>
|
||
|
|
|
||
|
|
Para prevenir este comportamiento, puede agregar `@submit.native.prevent` on `<el-form>`.
|
||
|
|
:::
|
||
|
|
|
||
|
|
### Formulario inline
|
||
|
|
|
||
|
|
Cuando el espacio vertical es limitado y la forma es relativamente simple, puede ponerlo en una unica línea.
|
||
|
|
|
||
|
|
:::demo Establezca el atributo `inline` como `true` y el formulario sera inline.
|
||
|
|
|
||
|
|
```html
|
||
|
|
<el-form :inline="true" :model="formInline" class="demo-form-inline">
|
||
|
|
<el-form-item label="Approved by">
|
||
|
|
<el-input v-model="formInline.user" placeholder="Approved by"></el-input>
|
||
|
|
</el-form-item>
|
||
|
|
<el-form-item label="Activity zone">
|

|
|
<el-select v-model="formInline.region" placeholder="Activity zone">

### Alineamiento
|
||
|
|
|
||
|
|
Dependiendo de su diseño, hay varias maneras diferentes de alinear el elemento de la etiqueta.
|
||
|
|
|
||
|
|
:::demo El atributo `label-position` decide cómo se alinean las etiquetas, puede estar `top` o `left`. Cuando se establece en `top`, las etiquetas se colocarán en la parte superior del campo de formulario.
|
||
|
|
|
||
|
|
```html
|
||
|
|
<el-radio-group v-model="labelPosition" size="small">
|
||
|
|
<el-radio-button label="left">Left</el-radio-button>
|
||
|
|
<el-radio-button label="right">Right</el-radio-button>
|
||
|
|
<el-radio-button label="top">Top</el-radio-button>
|
||
|
|
</el-radio-group>
|
||
|
|
<div style="margin: 20px;"></div>

### Validación
|
||
|
|
|
||
|
|
El componente `form` le permite verificar sus datos, ayudándole a encontrar y corregir errores.
|
||
|
|
|
||
|
|
:::demo Sólo tiene que añadir el atributo `rules` en el componente `Form`, pasar las reglas de validación y establecer el atributo `prop` para `Form-Item` como una clave específica que necesita ser validada. Ver más información en [async-validator](https://github.com/yiminghe/async-validator).

### Validación numérica
|

### Tamaño del control
|

Todos los componentes de un formulario heredan su atributo `size`. De manera similar, FormItem también tiene un atributo `size`.

|
|
|
||
|
|
:::demo Aún así, puede ajustar el `size` de cada componente si no desea que herede su tamaño de From o FormItem.
