When transmitting data from the parent component to the child component, the data successfully passes through, yet the view fails to reflect the

I'm facing an issue with passing data from a parent component to a child component using props. Here is the code snippet I'm working with:

<div id="root">
    <my-component v-bind:account-types='accountTypes'>
    </my-component>
</div>

Vue.component('my-component', {
   props: ['accountTypes'],
   data() {
    return { accounts: Object.assign({},this.accountTypes) }
   },
    template: `
       <div v-for="x in accounts"></div> // This line is returning 0
    `
}

Even though the Vue debugger extension shows that my-component has the accountTypes, it doesn't seem to display them properly.

The structure of the object I'm working with looks like this:

 var obj = {
      1 : [ "a", "z", "k", "m" ]
      2 : [ "a", "b", "c", "d" ]
 }

In my main app, I have the following:

var app = new Vue({

el: '#root',

data: {
    accountTypes : {},
}, 



methods : {
    // selecting & pushing
    accountTypeSelected(clientIndex, formName, action) {
        if (action == 'add') {
            this.pushValue(clientIndex, formName)
        } else {
            this.removeFromArray(clientIndex, formName)
        }
    },

 // Methods for pushing and deleting values:
    pushValue(key, value) {
        var obj = this.accountTypes

        if (obj.hasOwnProperty(key)) {
            var idx = $.inArray(value, obj[key]);
            if (idx == -1) {
                obj[key].push(value);
            }
        } else {
            obj[key] = [value];
        }
    },

    removeFromArray(key, val) {
        var idx = $.inArray(val, this.accountTypes[key]);
        if (idx != -1) {
            this.accountTypes[key].splice(idx, 1);
        }
    }
}

Answer №1

When setting up accounts using accountTypes, keep in mind that initialization only happens once. Any changes made to accountTypes will not affect the initialization of accounts.

If you want the child to always reflect the parent, consider eliminating accounts and solely relying on accountTypes.
