我有一个项目,这个项目是为购买汽车和许多其他操作的车主购买,但我有一个表中的几个列,在这些列中有一列我听取行动,这列包含一个按钮称为编辑,我想当我点击编辑按钮被用来修改此文件内的组件,我怎么做呢?它是编辑表单所在的编辑文件。Edit.vue:
<template>
<v-row justify="center">

onSaveChanges() {

UpdatedCar.name = this.editedName;
UpdatedCar.price = this.editedPrice;
UpdatedCar.seatsNumber = this.editedNumberOfSeats;
this.editCarInformations(UpdatedCar);
},
},
};
</script>这个文件中有一个表,其中有几列,最后一列是Action,它包含Modify按钮,Modify按钮,当我按下它时,修改的范围被调用。viewAllCars:

首先,您不需要在Edit.vue中使用"v-row“。去掉它。
因为你有按钮作为激活器,你应该像Avraham提到的那样添加组件。但是您需要知道这种方法有一些注意事项。
,
更好的解决方案是只添加Edit.vue的一个实例,并使用v-if在DOM中添加/删除组件。
这将使您的表使用一个Edit.vue实例,添加和删除组件将处理数据重置。
像这样的东西
在包含v-data-table的文件中,按如下方式更新模板
<template>
......
<v-data-table ...>
...
<template #[`item.actions`]="{ item }">
<v-btn icon @click="edit(item.id)">
<v-icon>mdi-pencil</v-icon>
</v-btn>
<v-btn icon @click="delete(item.id)">
<v-icon>mdi-delete</v-icon>
</v-btn>
</template>
...
</v-data-table>
<edit :car="item" v-if="showEditDialog = true" @closed="showEditDialog = false" />
......
</template>
<script>
import Edit from 'Edit.vue'
export default {
components: { Edit },
data: () =({
item: {},
showEditDialog: false,
}),
methods: {
edit(item) {
this.item = item
this.showEditDialog = true
}
}
}
</script>在您的Edit.vue中,为"editDialog“属性添加一个监视器,以发出一个事件以从DOM中删除编辑对话框。
watch: {
editDialog(val){
if(!val)
this.$emit('closed')
}
}并从Edit.Vue中删除此部件
<template v-slot:activator="{ on, attrs }">
<v-btn
fab
accent
class="grey lighten-1 margin pa-4"
dark
v-bind="attrs"
v-on="on"
>
<v-icon>
mdi-pencil
</v-icon>
</v-btn>
</template>祝好运。

您应该在汽车查看器组件中导入Edit.vue组件,并使用它而不是编辑按钮:
...
<template #[`item.actions`]="{ item }">
<!-- Pass the item to the `car` prop -->
<edit :car="item" />
<v-btn icon @click="delete (item.id)">
<v-icon>mdi-delete</v-icon>
</v-btn>
</template>
...
<script>
import Edit from 'Edit.vue' // make sure the path to the component is correct
export default {
components: { Edit },
...
};
