Utilizing Vue.js and Vuetify's slot-scope feature

Utilizing Vue.js and Vuetify's slot-scope feature

I'm struggling to understand how slot-scopes function. Can anyone provide some guidance on this seemingly straightforward issue?

<v-data-table>
    <template slot="items" slot-scope="props">
        <tr @click="props.expanded = !props.expanded">

My goal is to manually update "props" to expand this row based on an external event. However, I am having trouble accessing it outside of the specified context. The props.expanded = !props.expanded line works perfectly fine.

Any suggestions or solutions for this problem?

The component does not have a built-in way to access the expanded object because it creates its own and does not use a passed-in prop.

One workaround is to use a ref. You can find more information about this on the Vue page on child component refs.

To set a ref on the data table as "accesshere," you can use the following code snippet:

<v-data-table ref="accesshere" :headers="headers" :items="dataTable" 
:search="search" item-key="id">

After setting the ref, you can access the object using

this.$refs.accesshere.expanded['nameofkey'] = false

(setting this to false will close the expanded table row).

You can see this in action on this codepen.

There is an issue with the expanded object not being populated until you expand a row for the first time. If you need to force the component to update and see changes immediately, consider using the method below:

 methods: {
   itemShow () {
     this.$refs.accesshere.expanded['2'] = true
     this.$forceUpdate() // This works but may not be recommended
  }
 }
