您有 2 个选项 - 插槽和动态组件。
让我们首先探索插槽:
<template>
<v-data-table :items="dataItems" :headers="headerItems">
<template slot="item.phone_number" slot-scope="{item}">
<v-chip>{{ item.phone_number }}</v-chip>
</template>
<template slot="item.company_name" slot-scope="{item}">
<v-chip color="pink darken-4" text-color="white">{{ item.company_name }}</v-chip>
</template>
</v-data-table>
</template>
数据表为您提供了可以自定义内容的位置。如果您想让您的组件更可重用并希望从您的父组件填充这些插槽 - 那么您需要将这些插槽重新公开给父组件:
<template>
<v-data-table :items="dataItems" :headers="headerItems">
<template slot="item.phone_number" slot-scope="props">
<slot name="phone" :props="props" />
</template>
<template slot="item.company_name" slot-scope="props">
<slot name="company" :props="props" />
</template>
</v-data-table>
</template>
如果您不知道要自定义哪些槽 - 您可以重新公开所有数据表槽:
<template>
<v-data-table
:headers="headers"
:items="items"
:search="search"
hide-default-footer
:options.sync="pagination"
:expanded="expanded"
class="tbl_manage_students"
height="100%"
fixed-header
v-bind="$attrs"
@update:expanded="$emit('update:expanded', $event)"
>
<!-- https://devinduct.com/blogpost/59/vue-tricks-passing-slots-to-child-components -->
<template v-for="(index, name) in $slots" v-slot:[name]>
<slot :name="name" />
</template>
<template v-for="(index, name) in $scopedSlots" v-slot:[name]="data">
<slot :name="name" v-bind="data" />
</template>
<v-alert slot="no-results" color="error" icon="warning">
{{ $t("no_results", {term: search}) }}"
</v-alert>
<template #footer="data">
<!-- you can safely skip the "footer" slot override here - so it will be passed through to the parent component -->
<table-footer :info="data" @size="pagination.itemsPerPage = $event" @page="pagination.page = $event" />
</template>
</v-data-table>
</template>
<script>
import tableFooter from '@/components/ui/TableFooter'; // you can safely ignore this component in your own implementation
export default
{
name: 'TeacherTable',
components:
{
tableFooter,
},
props:
{
search:
{
type: String,
default: ''
},
items:
{
type: Array,
default: () => []
},
sort:
{
type: String,
default: ''
},
headers:
{
type: Array,
required: true
},
expanded:
{
type: Array,
default: () => []
}
},
data()
{
return {
pagination:
{
sortDesc: [false],
sortBy: [this.sort],
itemsPerPageOptions: [25, 50, 100],
itemsPerPage: 25,
page: 1,
},
};
},
watch:
{
items()
{
this.pagination.page = 1;
},
sort()
{
this.pagination.sortBy = [this.sort];
this.pagination.sortDesc = [false];
},
}
};
</script>
动态组件可以通过 props 提供:
<template>
<v-data-table :items="dataItems" :headers="headerItems">
<template slot="item.phone_number" slot-scope="{item}">
<component :is="compPhone" :phone="item.phone_number" />
</template>
<template slot="item.company_name" slot-scope="{item}">
<component :is="compCompany" :company="item.company_name" />
</template>
</v-data-table>
</template>
<script>
export default
{
name: 'MyTable',
props:
{
compPhone:
{
type: [Object, String], // keep in mind that String type allows you to specify only the HTML tag - but not its contents
default: 'span'
},
compCompany:
{
type: [Object, String],
default: 'span'
},
}
}
</script>
槽比动态组件更强大,因为它们(槽)使用依赖倒置原则。你可以在Markus Oberlehner's blog阅读更多内容
