## Radio
|
|
Selección única entre múltiples opciones.
|
|
|
|
### Uso básico
|
|
El elemento Radio no debe tener muchas opciones. De otra manera, utilice el componente Select.
|
|
|
|
:::demo Crear un elemento Radio es fácil, solo necesita enlazar(`bind`) una variable a la directiva `v-model` del Radio. Va a ser igual al valor `label` del Radio seleccionado. El tipo de dato de `label` es `String`, `Number` o `Boolean`.
|
|
```html
|
|
<template>
|
|
<el-radio v-model="radio" label="1">Option A</el-radio>
|
|
<el-radio v-model="radio" label="2">Option B</el-radio>
|
|
</template>
|
|
|
|
<script>
|
|
export default {
|
|
data () {
|
|
return {
|
|
radio: '1'
|
|
};
|
|
}
|
|
}
|
|
</script>
|
|
<!--
|
|
<setup>
|
|
import { defineComponent, ref } from 'vue'
|
|
|
|
export default defineComponent({
|
|
setup() {
|
|
return {
|
|
radio: ref('1'),
|
|
}
|
|
}
|
|
})
|
|
</setup>
|
|
-->
|
|
```
|
|
:::
|
|
|
|
### Deshabilitado
|
|
|
|
El atributo `disabled` es utilizado para deshabilitar un Radio.
|
|
|
|
:::demo Solo necesita agregar el atributo `disabled`.
|
|
```html
|
|
<template>
|
|
<el-radio disabled v-model="radio" label="disabled">Option A</el-radio>
|
|
<el-radio disabled v-model="radio" label="selected and disabled">Option B</el-radio>
|
|
</template>
|
|
|
|
<script>
|
|
export default {
|
|
data () {
|
|
return {
|
|
radio: 'selected and disabled'
|
|
};
|
|
}
|
|
}
|
|
</script>
|
|
<!--
|
|
<setup>
|
|
import { defineComponent, ref } from 'vue'
|
|
|
|
export default defineComponent({
|
|
setup() {
|
|
return {
|
|
radio: ref('selected and disabled'),
|
|
}
|
|
}
|
|
})
|
|
</setup>
|
|
-->
|
|
```
|
|

|
|
|
|
### Grupo de elementos Radio
|
|
|
|
Recomendado para seleccionar opciones que se excluyen mutuamente.
|
|
|
|
:::demo Combine `el-radio-group` con `el-radio` para mostrar un grupo de Radios. Enlace la variable con `v-model` del elemento `el-radio-group` y asigne el valor del `label` en `el-radio`. Se provee el evento `change` con el valor actual como parámetro.
|
|
|
|
```html
|
|
<el-radio-group v-model="radio">
|
|
<el-radio :label="3">Option A</el-radio>
|
|
<el-radio :label="6">Option B</el-radio>
|
|
<el-radio :label="9">Option C</el-radio>
|
|
</el-radio-group>
|
|
|
|
<script>
|
|
export default {
|
|
data () {
|
|
return {
|
|
radio: 3
|
|
};
|
|
}
|
|
}
|
|
</script>
|
|
<!--
|
|
<setup>
|
|
import { defineComponent, ref } from 'vue'
|
|
|
|
export default defineComponent({
|
|
setup() {
|
|
return {
|
|
radio: ref(3),
|
|
}
|
|
}
|
|
})
|
|
</setup>
|
|
-->
|
|
```
|
|

### Estilo Button
|
|
|
|
Radio con estilo de botón.
|
|
|
|
