Tips for assigning a value to a data property within a different Vue component

I am faced with a situation where I have two Vue components. The first one triggers the opening of a modal, while the second one serves as the content within that modal in the form of a table and a brief form. Upon completing the form, my goal is to click on the save button within the content component, which should then save the content into an array and close the modal. However, the issue arises from the fact that the content component is nested within another component and is linked to a field in the same component. Even after attempting to set it to false by directly accessing the Component from my child component, it does not work despite being able to see that it is indeed false when using console.log. Could someone please take a look at my code?

DialogComponent:

html:

<v-dialog
          class="mx-auto my-auto "
          v-model="dialog"
          persistent
          max-width="fit-content"
          width="fit-content" >
        <template v-slot:activator="{ on, attrs }">
          <v-btn
              color="primary"
              dark
              v-bind="attrs"
              v-on="on"
              rounded
          >
            Add date
          </v-btn>
        </template>
        <v-card>
          <v-card-title>
            <span class="headline">Generate Groups</span>
          </v-card-title>
          <v-card-text>

          </v-card-text>
          <v-divider class="mx-4"/>


          <AddGroupsModal :new-group.sync="meetingsArray"/>
        </v-card>
      </v-dialog>

Script:

data : ()=>({
    dialog: false,
    menu: false,
    modal: false,
    menu2: false,
    menu3: false,
    meetingsArray: []

  }),

Child/Content:

generateGroup(){

     const newMeeting = {meetingUrl: "", meetingName: "", date: this.selectedDate, startTime: "", endTime: ""};
    let finalMeetingArray = [];

    this.model.forEach((model, i) => {
      const key = `participant${i + 1}`;
      newMeeting[key] = model.voterUniqueName;
      newMeeting.startTime = model.startTime;
      newMeeting.endTime = model.endTime
    })
    this.newGroup = [],
    finalMeetingArray.push(newMeeting)
    this.newGroup.push(newMeeting)
    console.log(JSON.stringify(this.newGroup))
    MeetingAdminComponent.data().dialog = false;  -> here I am trying to close the 
    modal
    console.log(MeetingAdminComponent.data().dialog) 

  }

Answer №1

It could be considered an Anti-pattern to approach this problem in the way you are currently attempting. A cleaner solution would involve maintaining separation and following the recommended parent/child communication outlined in the official guide (links provided below). The suggested approach is to use props for communication with your child components, or emit events to communicate with parent components.

For instance, within your child component, you could have a method like this:

methods: {
 myMethod() {
  // Implement your logic here
  // More code
  this.$emit('saved', somedata)
 }
}

And then in your parent component, you can listen for the event like so:

<ChildComponentName v-on:saved="handleSaveEvent"></ChildComponentName>

For more detailed information, please refer to the following resources:

Official Vue.js Guide - Components

Listening to Child Components Events - Vue.js Documentation

Answer №2

Have you experimented with using $refs?

<YourComponent ref="yourComponent" />
methods: {
  callChildMethod() {
    this.$refs.yourComponent.childMethod()
  }
}
