Dynamic options can now be accessed and modified using newly computed getters and setters

When using Vuex with Vue components, handling static fields that are editable is easily done through computed properties:

computed: {
  text: {
    get() {
      return ...
    },
    set(value) {
      this.$store.commit...
    },
  },
},

<input type="text" v-model="text">

But what about when rendering a list of options that need to be bound?

options = [
  {
    value: ...,
    text: ...,
  },
  {
    value: ...,
    text: ...,
  },
  ...
];

<input type="text" v-model="option.text" v-for="option in options">

Answer №1

When working with mutations, it's important to define them clearly, with actions like "addOption" or "editOption."

It is highly recommended to create an options component and bind events to trigger the mutations for seamless functionality.

If you need a good example to reference, Vuex provides a straightforward demo in their todo list implementation: https://github.com/vuejs/vuex/tree/dev/examples/todomvc

Pay close attention to the todo component, which manages individual items in the list: https://github.com/vuejs/vuex/blob/dev/examples/todomvc/components/Todo.vue

Also, observe how these components interact within the app component: https://github.com/vuejs/vuex/blob/dev/examples/todomvc/components/App.vue

Take a look at the mutations as well, where you can see how they handle editing, adding, and deleting list items: https://github.com/vuejs/vuex/blob/dev/examples/todomvc/store/mutations.js

Transitioning to Vue + Redux methodology (Vuex) requires a paradigm shift in your thinking and overall architecture.

If you want to represent these choices in your Vue instance, you can define them as data and then use them within your HTML code just as you described.

var vm = new Vue({
  data: {
     options: [
       {
         value: ...,
         text: ...,
       },
       {
         value: ...,
         text: ...,
       },
       ... 
     ]
  }
})

In your HTML code:

<input type="text" v-model="option.text" key="option.value" v-for="option in options">

Make sure to include a key attribute along with the v-for directive. This allows Vue to effectively track each node's identity and optimize the reuse and reordering of elements. The key should ideally be a unique identifier for each item.
