Acquiring information from a different Vue.js component

Question

Acquiring information from a different Vue.js component

I am faced with a puzzle involving 2 components, A and B.

Component A:

import B from '../components/B.vue';

export default {

    components: {
        B
    },

    methods: {
        test: function() {
            console.log(B.data().settings);
        }
    }
}

As for component B:

export default {

    data() {
        return {
            setting: '123'
        }
    }

}

Each time I trigger the test method, the value returned is 123. However, when I input a new value and trigger the test method again, the value remains at 123. I am quite puzzled by this. Any help would be greatly appreciated. Thank you!

Answer №1

When working with the data function of a component's definition, you can easily access the desired value from the instance of the component by simply calling the specific data you need. For instance:

import B from '../components/B.vue';

// Remember to work on the instance of Vue, not within the components definition
let b = new B()

console.log(b.settings) // This will display the settings for that instance, with reactive properties
console.log(b.$data) // This will show all the current data for that component, also being reactive
console.log(B.data()) // This will display the definition data, which is not reactive

It is important to figure out how to obtain a reference to the B instance from the A Vue instance, especially if there are multiple B components within A.
