我有這個過濾器功能（屬于 List 組件），然后我需要將結果傳遞給另一個組件（它們是兄弟組件）來填充我的 DataTable（父組件）：
async filtroVariaveis () {
try {
this.loading = true;
this.variaveis = await this.variaveisService.listVariables();
let idGrupos = null;
if (!this.grupos[0] && this.maquinaSelecionada[0]) {
idGrupos = this.gruposOpcoes.map(m => m.id);
}
if (!this.grupos[0] && !this.maquinaSelecionada[0] && this.areaSelecionada[0]) {
const idMaquinas = this.maquinasOpcoes.map(m => m.id);
const grupo = this.gruposOpcoes.filter(a => idMaquinas.includes(a.id_maquina));
idGrupos = grupo.map(a => a.id);
}
if (this.grupos[0]) {
idGrupos = this.grupos.map(g => g.id);
}
const tipos = this.tipoVariavel.map(t => t === "Analógica" ? t = "ANALOGICA" : "DIGITAL");
const tag = this.tagInput || this.variaveis.map(t => t.tag);
const descricao = this.descricaoInput || this.variaveis.map(d => d.descricao);
this.filtroAplicado = ((await this.variaveisService.listVariables(idGrupos, tipos, tag, descricao)) || []);
} catch (err) {
console.log(err);
}
this.variaveisService 是我的 Axios 服務，它與我的 API 進行通信。

我的 GenericList 組件，我需要在其中放置這些資料：

我不知道如何填寫這個資料表，有人可以幫助我嗎？
uj5u.com熱心網友回復：
您可以使用$emit和$on在同級組件之間傳遞資料。請看這個例子
當您將資料傳遞到另一個組件時，您必須設定這一行：
this.$root.$emit('eventing', data);
之后，您可以像這個示例一樣將資料接收到目標組件中：
1)
mounted() {
this.$root.$on('eventing',this.functionName);
}
或者
2)
mounted() {
this.$root.$on('eventing', data => {
console.log(data);
});
}
請注意，最好設定$off成目標組件
1)
beforeDestroy() {
this.$root.$off("eventing", this.functionName);
}
或者
2)
beforeDestroy() {
this.$root.$off("eventing");
}
你可以在引數中找到你需要的資料 this.functionName
