## Checkbox
|
|
|
|
Un groupe d'options à choix multiples.
|
|
|
|
### Usage
|
|
|
|
Checkbox peut être utilisé seul pour switcher entre deux états.
|
|
|
|
:::demo Définissez `v-model` (variable liée) dans `el-checkbox`. La valeur par défaut est un `Boolean` pour une seule `checkbox` et devient `true` quand elle est sélectionnée. Le contenu à l'intérieur de la balise `el-checkbox` deviendra le label du bouton de la checkbox.
|
|
|
|
```html
|
|
<template>
|
|
<div>
|
|
<el-checkbox v-model="checked1" label="Option 1"></el-checkbox>
|
|
<el-checkbox v-model="checked2" label="Option 2"></el-checkbox>
|
|
</div>
|
|
<div>
|
|
<el-checkbox v-model="checked3" label="Option 1" size="medium"></el-checkbox>
|
|
<el-checkbox v-model="checked4" label="Option 2" size="medium"></el-checkbox>
|
|
</div>
|
|
<div>
|
|
<el-checkbox v-model="checked5" label="Option 1" size="small"></el-checkbox>
|
|
<el-checkbox v-model="checked6" label="Option 2" size="small"></el-checkbox>
|
|
</div>
|
|
<div>
|
|
<el-checkbox v-model="checked7" label="Option 1" size="mini"></el-checkbox>
|
|
<el-checkbox v-model="checked8" label="Option 2" size="mini"></el-checkbox>
|
|
</div>
|
|
</template>
|
|
<script>
|
|
export default {
|
|
data() {
|
|
return {
|
|
checked1: true,
|
|
checked2: false,
|
|
checked3: false,
|
|
checked4: false,
|
|
checked5: false,
|
|
checked6: false,
|
|
checked7: false,
|
|
checked8: false,
|
|
};
|
|
}
|
|
};
|
|
</script>
|
|
<!--

<setup>
|
|
|
|
import { defineComponent, ref } from 'vue';
|
|
|
|
export default defineComponent({
|
|
setup() {

checked1,

|
|
});
|
|
|
|
</setup>
|
|
-->
|
|
```
|
|

|
|
|
|
### Désactivation
|
|
|
|
La checkbox peut être désactivée.
|
|
|
|
:::demo Ajouter l'attribut `disabled`.
|
|
|
|
```html
|
|
<template>
|
|
<el-checkbox v-model="checked1" disabled>Option</el-checkbox>
|
|
<el-checkbox v-model="checked2" disabled>Option</el-checkbox>
|
|
</template>
|
|
<script>
|
|
export default {
|
|
data() {
|
|
return {
|
|
checked1: false,
|
|
checked2: true
|
|
};
|
|
}
|
|
};
|
|
</script>
|
|
<!--
|
|
<setup>
|
|
|
|
import { defineComponent, ref } from 'vue';
|
|
|
|
export default defineComponent({
|
|
setup() {
|
|
const checked1 = ref(false);
|
|
const checked2 = ref(true);
|
|
return {
|
|
checked1,
|
|
checked2,
|
|
};
|
|
},
|
|
});
|
|
</setup>
|
|
-->
|
|
```

### Checkbox groupées
|
|
|
|
Utile pour grouper des checkbox, indiquant si une option est sélectionnée en vérifiant la case en question.
|
|
|
|
:::demo L'élément `checkbox-group` peut gérer plusieurs checkbox d'un groupe en utilisant `v-model`, qui sera un `Array`. Dans l'élément `el-checkbox`, `label` est la valeur de la checkbox. S'il n'y a aucun contenu dans la balise, `label` sera également la description de la checkbox. `label` correspond aussi aux valeurs des éléments dans le tableau. Il est sélectionné si la valeur spécifiée existe dans le tableau, et vice-versa.
|
|
|
|
```html
|
|
<template>
|
|
<el-checkbox-group v-model="checkList">
|
|
<el-checkbox label="Option A"></el-checkbox>
|
|
<el-checkbox label="Option B"></el-checkbox>
|
|
<el-checkbox label="Option C"></el-checkbox>
|
|
<el-checkbox label="Désactivée" disabled></el-checkbox>
|
|
<el-checkbox label="Sélectionnée et désactivée" disabled></el-checkbox>
|
|
</el-checkbox-group>
|
|
</template>
|
|
|
|
<script>
|
|
export default {
|
|
data () {
|
|
return {
|
|
checkList: ['selected and disabled','Option A']
|
|
};
|
|
}
|
|
};
|
|
</script>
|
|
<!--
|
|
<setup>
|
|
|
|
import { defineComponent, ref } from 'vue';
|
|
|
|
export default defineComponent({
|
|
setup() {
|
|
const checkList = ref(['selected and disabled','Option A']);
|
|
return {
|
|
checkList,
|
|
};

|
<el-checkbox-group v-model="checkedCities" @change="handleCheckedCitiesChange">
|
|
<el-checkbox v-for="city in cities" :label="city" :key="city">{{city}}</el-checkbox>
|
|
</el-checkbox-group>

|
</template>

checkAll: false,
|
|
checkedCities: ['Shanghai', 'Beijing'],

cities: cityOptions,

|
isIndeterminate: true
|
|
};

|
methods: {
|
|
handleCheckAllChange(val) {
|
|
this.checkedCities = val ? cityOptions : [];
|
|
this.isIndeterminate = false;
|
|
},
|
|
handleCheckedCitiesChange(value) {
|
|
let checkedCount = value.length;
|
|
this.checkAll = checkedCount === this.cities.length;
