** 例如，在这里，当我单击按钮时，我将多一个组件，这意味着它将有新数据，所以我想在按下“保存数据”按钮时将所有信息收集到一个数组中，我希望，很容易理解
<Child v-for="count in btnNumber" :key="count" @showData="getElements" />
<v-btn
color="primary"
elevation="10"
class="space"
large
@click="duplicateEl"
>Add Categ & Key</v-btn
>
v-btn
color="secondary"
elevation="13"
class="btnEl"
dark
large
@click="getResult"
>Save Data</v-btn
** 它使用 Emit 从我的子组件获取数据
methods:{
getElements(emitPayload) {
this.selectedChildCategory = emitPayload.selectedCateg;
this.selectedChildKey = emitPayload.selectedKey;
this.selectedChildLanguage = emitPayload.selectedLang;
this.selectedChildContent = emitPayload.selectedCon;
}
}
duplicateEl() {
this.btnNumber++;
} 
尝试将发出事件的数据（从获取元素）保存到新的数据变量数组，并使用该数组
您可以在父组件上保存数据，请查看以下代码片段：
Vue.component('Child', { template: `
`,
props: ['conte'],
data() {
return {
content: this.conte,
categories: ['first', 'second', 'third'],
keys: [1,2,3],
langs: ['g', 'h', 'j'],
contents: ['aaa', 'bbb', 'ccc']
}
},
methods: {
setD() {
this.$emit('show', this.content);
},
},
})
new Vue({
vuetify: new Vuetify(),
el: "#app",
data() {
return {
contentFields: [{id: 0, cat: '', key: '', lang: '', cont: ''}],
showData: false
}
},
methods: {
addInput() {
let newI = this.contentFields.length
this.contentFields.push({id: newI, cat: '', key: '', lang: '', cont: ''})
},
getElements(e){
const newData = this.contentFields.map(obj => {
if(obj.id === e.id)
return { ...obj }
return obj
});
},
getResult() {
this.showData = !this.showData
}
}
})
