Cascader
Si les options ont une structure hiérarchique claire, Le composant Cascader peut être utilisé pour les afficher et les sélectionner.
Basic usage
Il y a deux manières d'étendres les options enfants.
:::demo Assigner l'attribut options à un tableau d'options fournit un composant Cascader. L'attribut props.expandTrigger définit comment les options enfants sont étendues.
<div class="block">
<span class="demonstration"
>Les options enfants se développent lorsque vous cliquez dessus (par
défaut)</span
>
<el-cascader
v-model="value"
:options="options"
@change="handleChange"
></el-cascader>
</div>
<div class="block">
<span class="demonstration"
>Les options enfants se développent lorsqu'elles sont survolées</span
>
<el-cascader
v-model="value"
:options="options"
:props="{ expandTrigger: 'hover' }"
@change="handleChange"
></el-cascader>

Disabled option
Désactivez une option en définissant un champ disabled dans l'objet d'option.
:::demo Dans cet exemple, le premier élément du tableau options a un champ disabled: true, il est donc désactivé. Par défaut, Cascader vérifie le champ disabled dans chaque objet option. Si vous utilisez un autre nom de champ pour indiquer si une option est désactivée, vous pouvez l'affecter dans l'attribut props.disabled (voir le tableau des API ci-dessous pour plus de détails). Et bien sûr, les noms de champs value, label et children peuvent également être personnalisés de la même manière.

:::
Dynamic loading
Charge dynamiquement ses noeuds enfants lorsque un noeud est sélectionné.
:::demo Définissez lazy = true pour utiliser le chargement dynamique. Vous devez Spécifier comment charger la source de données avec lazyload. Il existe deux paramètres de lazyload, le premier paramètre node est le noeud sur lequel l'utilisateur a cliqué, et resolution est un callback indiquant que le chargement est terminé et qu'il doit être appelé. Pour afficher le statut du noeud plus précisément, vous pouvez ajouter un champ leaf (modifiable par props.leaf) pour indiquer s'il s'agit d'un noeud feuille. Sinon, il sera déduit par ses noeuds enfants.
<el-cascader :props="props"></el-cascader>
<script>
let id = 0
export default {
data() {
return {
props: {
lazy: true,
lazyLoad(node, resolve) {
const { level } = node
setTimeout(() => {
const nodes = Array.from({ length: level + 1 }).map((item) => ({
value: ++id,
label: `Option - ${id}`,
leaf: level >= 2,
}))
// Appelez le callback `resolve` pour renvoyer les données des noeuds enfants et indiquer que le chargement est terminé.
resolve(nodes)
}, 1000)
},
},
}
},
}
</script>
:::
Filterable
Rechercher et sélectionner des options avec un mot clé.
:::demo Ajouter filterable à el-cascader permet le filtrage. Cascader recherchera les noeuds dont l'étiquette ou l'étiquette du parent (selon show-all-levels) inclut le mot-clé input. Bien sûr, vous pouvez personnaliser la logique de recherche en utilisant filter-method qui accepte une fonction, le premier paramètre est node, le second est keyword et doit renvoyer une valeur booléenne indiquant si le résultat est positif.
