Tips for accessing a specific data value in a data table upon clicking in VueJS

I am working with a v-data-table displaying generic employee data. I'm trying to find out how I can retrieve the exact value of the cell that I click on.

This is a snippet of my current code:

Note: The CRUD-Actions Example from the official vuetify documentation is being used in this scenario: https://vuetifyjs.com/en/components/data-tables/

<v-data-table 
    :headers="headers" 
    :items="rows" 
    item-key="name" 
    :search="search" >

    <template v-slot:top>
        <!-- A dialog box for editing rows is located here -->                   
    </template>

    <template v-slot:item.actions="{ item }">
        <v-icon small class="mr-2" @click="editItem(item)">
            mdi-pencil
        </v-icon>
    </template>

</v-data-table>

Furthermore, I want to know if it's feasible to obtain the column name as well (based on the headers in the provided code). Thanks!

Answer №1

As per the documentation for v-data-table https://vuetifyjs.com/en/components/data-tables/, you can utilize the item slot:

<v-data-table
    :headers="headers"
    :items="desserts"
    :items-per-page="5"
    class="elevation-1"
  >    
    <template v-slot:item="props">
       <tr>      
          <td v-for="(prop, key) in props.item" :key="key" @click="onClickItem(key, props.item[key])">{{props.item[key]}}</td>
       </tr>
    </template>
</v-data-table>

You can retrieve the item using this method:

methods:{
  onClickItem(columName, value) {
     console.log(columName, value)
  },
}

UPDATE

If you want to add another column like actions, avoid using v-slot:item.actions slot because it will be overridden by v-slot:item. Adjust this property to achieve the desired outcome.

<v-data-table
    :headers="headers"
    :items="desserts"
    :items-per-page="5"
    class="elevation-1"
  >    
    <template v-slot:item="props">
     <tr>
      <td v-for="(prop, key) in props.item" :key="key" @click="onClickItem(key, props.item[key])">{{props.item[key]}}</td>

      <!-- This is for actions -->
      <td>
        <v-icon small class="mr-2" @click="editItem(item)">
          mdi-pencil
        </v-icon>
        <v-icon small @click="deleteItem(item)">
          mdi-delete
        </v-icon>
      </td>
     </tr>
    </template>
</v-data-table>
