## Diálogo

Informar usuarios cuando preserva el estado de página corriente.

### Basic usage

Diálogo que se surge una caja de diálogo,y es bastante personalizable.

:::manifestación Establece el atributo con un `Boolean`, y Diálogo muestra cuando es `true`.El Diálogo tiene dos partes:`body` y `footer`, y el último exige un `slot`llamado `footer`.El atributo opcional `title` (vacío por defecto) es para definir un título.Finalmente,este ejemplo demostra cómo `before-close` es usado.


```html
<el-button type="text" @click="dialogVisible = true">click to open the Dialog</el-button>

<el-dialog
  title="Tips"
  :visible.sync="dialogVisible"
  width="30%"
  :before-close="handleClose">
  <span>This is a message</span>
  <span slot="footer" class="dialog-footer">
    <el-button @click="dialogVisible = false">Cancel</el-button>
    <el-button type="primary" @click="dialogVisible = false">Confirm</el-button>
  </span>
</el-dialog>

<script>
  export default {
    data() {
      return {
        dialogVisible: false
      };
    },
    methods: {
      handleClose(done) {
        this.$confirm('Are you sure to close this dialog?')
          .then(_ => {
            done();
          })
          .catch(_ => {});
      }
    }
  };
</script>
```
:::

:::propina

`before-close` solamente funciona cuando usuarios se hacen clic el icono de cerrar o el fondo.Si tienes botones que cercan el Diálogo en el `footer` que se llamado slot,puedes añadir que harías con `before-close` en controlador del evento click de los botones.
:::

### Personalizaciones


El contenido de Diálogo puede ser cualquier cosa,hasta una mesa o un formulario.Este ejemplo muestra cómo utilizar Mesa y Formulario de Element con Diálogo.

:::manifestación

```html
<!-- Table -->
<el-button type="text" @click="dialogTableVisible = true">open a Table nested Dialog</el-button>

<el-dialog title="Shipping address" :visible.sync="dialogTableVisible">
  <el-table :data="gridData">
    <el-table-column property="date" label="Date" width="150"></el-table-column>
    <el-table-column property="name" label="Name" width="200"></el-table-column>
    <el-table-column property="address" label="Address"></el-table-column>
  </el-table>
</el-dialog>

<!-- Form -->
<el-button type="text" @click="dialogFormVisible = true">open a Form nested Dialog</el-button>

<el-dialog title="Shipping address" :visible.sync="dialogFormVisible">
  <el-form :model="form">
    <el-form-item label="Promotion name" :label-width="formLabelWidth">
      <el-input v-model="form.name" auto-complete="off"></el-input>
    </el-form-item>

        <el-option label="Zone No.2" value="beijing"></el-option>

    <el-button @click="dialogFormVisible = false">Cancel</el-button>
    <el-button type="primary" @click="dialogFormVisible = false">Confirm</el-button>
  </span>
</el-dialog>

<script>
  export default {
    data() {
      return {
        gridData: [{
          date: '2016-05-02',
          name: 'John Smith',
          address: 'No.1518,  Jinshajiang Road, Putuo District'
        }, {
          date: '2016-05-04',
          name: 'John Smith',
          address: 'No.1518,  Jinshajiang Road, Putuo District'
        }, {
          date: '2016-05-01',
          name: 'John Smith',
          address: 'No.1518,  Jinshajiang Road, Putuo District'

    }
  };

### Diálogo anidado
Si un cuadro de diálogo está anidado en otro cuadro de diálogo,`append-to-body` es requerido.
:::manifestación Normalmente no recomendamos el uso de Diálogo anidado.Si necesitas varios cuadros de diálogo representados en la página,puedes aplastarlos simplemente así que serían hermanos el uno al otro.Si tienes que anidar un cuadro de diálogo dentro de otro cuadro de diálogo,establece `append-to-body` del diálogo anidado a verdadero,y se agregará al cuerpo en combio de su nodo padre,asi que ambos diálogos pueden ser renderizados correctamente.

```html
<template>
  <el-button type="text" @click="outerVisible = true">open the outer Dialog</el-button>
  
  <el-dialog title="Outter Dialog" :visible.sync="outerVisible">
    <el-dialog
        width="30%"
        title="Inner Dialog"
        :visible.sync="innerVisible"
        append-to-body>
    </el-dialog>
    <div slot="footer" class="dialog-footer">
      <el-button @click="outerVisible = false">Cancel</el-button>
      <el-button type="primary" @click="innerVisible = true">open the inner Dialog</el-button>
    </div>
  </el-dialog>
</template>

<script>
  export default {
    data() {
      return {
        outerVisible: false,
        innerVisible: false
      };
    }
  }
</script>
```

### Centered content
Dialog's content can be centered.

:::demo Setting `center` to `true` will center dialog's header and footer horizontally.

```html
<el-button type="text" @click="centerDialogVisible = true">Click to open the Dialog</el-button>

<el-dialog
  title="Warning"
  :visible.sync="centerDialogVisible"
  width="30%"
  center>
  <span>It should be noted that the content will not be aligned in center by default</span>
  <span slot="footer" class="dialog-footer">
    <el-button @click="centerDialogVisible = false">Cancel</el-button>
    <el-button type="primary" @click="centerDialogVisible = false">Confirm</el-button>
  </span>
</el-dialog>

<script>
  export default {
    data() {
      return {
        centerDialogVisible: false
      };
    }
  };
</script>
```
:::

:::propina
`center` afecta a cabezazos y pies de Diálogo.El cuerpo de Diálogo puede ser cualquier cosa,asi que a veces no puede verse bien cuando está centrado.Necesitas escribir algunos CSS si quieres centrar el cuerpo también.
:::

:::propina
If the variable bound to `visible` is managed in Vuex store, the `.sync` can not work properly. In this case, please remove the `.sync` modifier, listen to `open` and `close` events of Dialog, and commit Vuex mutations to update the value of that variable in the event handlers.
