Suggestions for changing sub-component data in Vue

I have a scenario where I am using a component with tabs inside. The Head component (parent) includes the following code:

<v-btn @click="setSelectedTab('Set') "> ... 
<component :is="selectedTab"></component>

Within the Set component (child component), I have some emits that will modify the data.

 <div>
    <head-set
      v-show="showHeadSet"
      @settings="
        showHeadSet = false;
        showScreenSettings = true;
      "
      @robotix="
        showHeadSet = false;
        showRobotix = true;
      "
    >
    </head-set>
    <Robotix v-show="showRobotix"></Robotix>
    <screen-settings v-show="showScreenSettings"></screen-settings>
  </div>

<script>
data() {
    return {
      showHeadSet: true,
      showRobotix: false,
      showScreenSettings: false,
    };
  },
</script>

When the button is clicked (

@click="setSelectedTab('Set') "

), my goal is to reset the data in the Set component back to its initial state (

showHeadSet: true,showRobotix: false,showScreenSettings: false,

).

Do you have any suggestions on how to achieve this?

Answer №1

To effectively pass data to child components in your scenario, utilizing properties is the most straightforward approach.

Here's how your parent component would appear:

<template>
  <div>
    <v-btn @click="setSelectedTab('Set') "> ... </v-btn>
    <component :is="selectedTab" :settings="yourSettings"></component>
  </div>
</template>

<script>
export default {
  data: () => ({
    yourSettings: {
      showHeadSet: true,
      showRobotix: false,
      showScreenSettings: false
    }
  }),

  methods: {
    setSelectedTab() {
      // your code
      this.yourSettings = {
        showHeadSet: true,
        showRobotix: false,
        showScreenSettings: false
      };
    }
  }
}
</script>

In the child components, make sure to define the props like so:

<script>
export default {
  props: {
    settings: {
      type: Object,
      required: true
    }
  }
}
</script>

You can utilize the props as computed or data variables and modify the settings based on your requirements. When using the setSelectedTab method in the parent component, you can simply revert the data back to its default state.

For more information regarding props, refer to the documentation.
