我正在尝试实现一个表,该表允许用户通过使用编辑按钮切换来编辑行。
我能够实现切换功能,但遇到了一个问题,它切换所有行而不是单行。
我相信我必须按索引选择行,并且通过我的实现我可以这样做,但似乎我无法找到它的任何用途。
Vue.component('employee-data', {
template:
/*html*/
`
<b-container>
<h3>Employee Data</h3>
<b-pagination v-model="currentPage" :total-rows="rows" :per-page="perPage"
aria-controls="employee-table"></b-pagination>
<b-table striped hover :items="employees" id="employee-table"
:per-page="perPage" :current-page="currentPage" :fields="fields">
<template v-slot:cell(employeeName)="row" v-if="edit">
<b-form-input v-model="row.item.employeeName"/>
</template>
<template v-slot:cell(joinDate)="row" v-if="edit">
<b-form-input v-model="row.item.joinDate"/>
</template>
<template v-slot:cell(selectedDepartment)="row" v-if="edit">
<b-form-input v-model="row.item.selectedDepartment"/>
</template>
<template v-slot:cell(jobDescription)="row" v-if="edit">
<b-form-input v-model="row.item.jobDescription"/>
</template>
<template v-slot:cell(actions)="row">
<b-button @click="toggleEdit(row.index)">
{{ edit ? 'Save' : 'Edit' }}
</b-button>
</template>
</b-table>
</b-container>

编辑:Here is the JSFiddle showing the issue
最佳答案
如果您有一个唯一标识符(如 id)并且只想允许一次编辑一行,您可以设置您的 edit
id
的变量当前正在编辑的行。
您也可以使用通用插槽 v-slot:cell()
, 以减少您编写的模板数量。
例子
new Vue({
el: "#app",
data() {
return {
edit: null,
employees: [{
id: 0,
employeeName: "Jane",
joinDate: "11-11-1111",
selectedDepartment: "IT",
jobDescription: "Nerd"
},
{
id: 1,
employeeName: "Peter",
joinDate: "12-12-1212",
selectedDepartment: "Accounting",
jobDescription: "Moneier"
}
],
fields: [{
key: 'employeeName',
label: 'Employee Name',
sortable: true
},
{
key: 'joinDate',
label: 'Join Date',
sortable: true
},
{
key: 'selectedDepartment',
label: 'Selected Department',
sortable: true
},
{
key: 'jobDescription',
label: 'Job Description',
sortable: true
},
{
key: 'actions',
label: 'Actions'
}
]
}
},
computed: {
rows() {
return this.employees.length
}
},
methods: {
onEdit(id) {
this.edit = this.edit !== id ? id : null;
}
}
})

<script src="//cdnjs.cloudflare.com/ajax/libs/bootstrap-vue/2.18.1/bootstrap-vue.min.js"></script>
<div id="app">
<b-table striped hover :items="employees" :fields="fields">
<template v-slot:cell()="{ value, item, field: { key }}">
<template v-if="edit != item.id">{{ value }}</template>
<b-form-input v-else v-model="item[key]" />
</template>
<template v-slot:cell(actions)="{ item: { id }}">
<b-dropdown variant="primary" text="Actions">
<b-dropdown-item @click="onEdit(id)">{{ edit === id ? 'Save' : 'Edit' }}</b-dropdown-item>
<b-dropdown-divider></b-dropdown-divider>
<b-dropdown-item @click="onDelete(id)">Delete</b-dropdown-item>
</b-dropdown>
</template>
</b-table>
</div>
如果您没有每行的唯一标识符,或者希望能够一次编辑多行,您可以为您的项目添加一个标志(在示例中为
isEditing
),这将切换该行是否为当前是否正在编辑。示例 2
new Vue({
el: "#app",
data() {
return {
employees: [{
id: 0,
employeeName: "Jane",
joinDate: "11-11-1111",
selectedDepartment: "IT",
jobDescription: "Nerd"
},
{
id: 1,
employeeName: "Peter",
joinDate: "12-12-1212",
selectedDepartment: "Accounting",
jobDescription: "Moneier"
}
],
fields: [{
key: 'employeeName',
label: 'Employee Name',
sortable: true
},
{
key: 'joinDate',
label: 'Join Date',
sortable: true
},
{
key: 'selectedDepartment',
label: 'Selected Department',
sortable: true
},
{
key: 'jobDescription',
label: 'Job Description',
sortable: true
},
{
key: 'actions',
label: 'Actions'
}
]
}
},
computed: {
rows() {
return this.employees.length
}
},
methods: {
onEdit(item) {
if (item.isEditing)
item.isEditing = false;
else
this.$set(item, 'isEditing', true)
}
}
})
