Question

Bidirectional data binding with a nested object property. (Using VueJS and VueX)

I'm currently working on the following code snippet:

<script>
export default {
  computed: {
    editingItem: {
      get() {
        return this.$store.getters['editing/editingItem'];
      },
      set(newValue) {
        this.$store.commit('editing/UPDATE_EDITING', newValue);
      }
    },
    editingItemName: {
      get() {
        return this.editingItem.name;
      },
      set(newValue) {
        this.editingItem.name = newValue;
        this.editingItem = this.editingItem;
      }
    }
  },
}
</script>

Do you think I'm making this too complex? The workaround on the second line of the editingItemName set() is necessary to trigger the editingItem set() function.

Visit this informative article. It focuses on forms and demonstrates how to implement 2-way binding with vuex.

In your specific scenario, take a look at the code snippet provided. The telephone property is nested within an object.

myModule.js

const myModule = {
  state: {
    customerInfo: {
      name: '',
      telephone: ''
    }
  },
  getters: {
    getTelephone(state) {
      return state.customerInfo.telephone
    }
  },
  mutations: {
    setTelephone(state, payload) {
      state.customerInfo.telephone += payload
    },
  }
}
export default myModule;

form.vue

<template>
  <div>
    <input v-model="telephone"></input>
  </div>
</template>

<script>
export default {
  computed: {
    telephone: {
      get() {
        return this.$store.getters['getTelephone']
      },
      set(value) {
        this.$store.commit('setTelephone', value)
      }
    },
  }
}
</script>
