如何使用vuetify数据表显示数组的索引? [英] How to display the index of an array using the vuetify data table?

问题描述

我从服务器收到响应，该响应将数据数组传递给我的vue实例.我已经使用该数组完成了数据表.但是我只需要知道如何显示序列号的数组索引即可.

I have a response from server which has the array of data passing to my vue instance. I have completed the data table using that array.But all i need to know how can I display the index of my array for serial no.

我在这里附加我的组件代码 我的响应还可以，表格也可以.我只需要再增加一列并在其中显示索引值即可.

here i am attaching my component code My response is ok and table is ok too.I just need to increase a column more and display the index value there.

提前打个电话 我的阵列名称是客户.

Tnks in advance My array name is customers.

<v-data-table
  v-bind:headers="headers"
  v-bind:items="customers"
  v-bind:search="search"
  v-cloak
  >
  <template slot="items" scope="props">
  <td class="text-xs-center">@{{ props.item.id }}</td>
  <td class="text-xs-center">
    <v-edit-dialog
      lazy
      @{{ props.item.name }}
      >
      <v-text-field
        slot="input"
        label="Edit"
        v-model="props.item.name"
        single-line
        counter
        :rules="[max25chars]"
        ></v-text-field>
    </v-edit-dialog>
  </td>
  <td class="text-xs-center">@{{ props.item.email }}</td>
  <td class="text-xs-center">@{{ props.item.email }}</td>
  <td class="text-xs-center">@{{ props.item.created_at }}</td>
  <td class="text-xs-center">
    <v-btn small outline fab class="red--text" @click="showWarning(props.item.id)">
      <v-icon>mdi-account-remove</v-icon>
    </v-btn>
    <v-btn small outline fab class="green--text" @click="showWarning(props.item.id)">
      <v-icon>mdi-account-off</v-icon>
    </v-btn>
  </td>
  </template>
  <template slot="pageText" scope="{ pageStart, pageStop }">
    From @{{ pageStart }} to @{{ pageStop }}
  </template>
</v-data-table>

推荐答案

编辑7/30/19 如@ titou10所述， Vuetify 2.0 中没有索引字段.

EDIT 7/30/19 As @titou10 mentioned, there is no index field within Vuetify 2.0.

四处逛逛后，我能够通过使用item.<name> 插槽.该插槽将为我返回item.我基于对象id创建了一个ID数组，并调用了indexOf(item.id)来获取索引位置.

After looking around for a bit I was able to achieve this by utilizing the item.<name> slot. This slot will return me an item. I created an array of IDs based on the object id and called indexOf(item.id) to get the index position.

电笔此处.

Vuetify 1.x

每个props对象之一包含两个键:item和index.您可以通过执行props.index来访问每个项目的索引.添加新标头就像将新项目添加到标头数组一样容易.

Each one of your props object contains two keys: item and index. You can access the index for each item by doing props.index. Adding a new header is as easy as adding a new item to your headers array.

这里是一个Codepen的例子.我将数据表的第一列更改为索引位置.

Here is a codepen as an example. I am changing the first column of the data-table to the index position.
