[Vuejs]-Assign all elements inside object to empty string

You could take an iterative and recursive approach by iterating all keys of the object and recursive by object values.

function empty(object) {
    Object.keys(object).forEach(function (k){
        if (object[k] && typeof object[k] === 'object') {
            return empty(object[k]);
        }
        object[k] = '';
    });
}

var object = { errors: { login: { foo: 43, bar: 23 }, register: { baz: 'aaa', inner: { key: 'value' } } } };

empty(object);

console.log(object);
.as-console-wrapper { max-height: 100% !important; top: 0; }

Solved.

In fact no need to do some recursive stuff or whatever. Just:

  • Declare errors at null in your data’s component
  • Declare a resetErrors() method who instanciate this.errors like you want, and call that function when your component is created()
  • Call this.resetErrors() whenever you want to reset/clear your errors object.
const app = new Vue({
  el: '#app',
  data() {
    return {
      errors: null
    }
  },

  methods: {

    resetErrors() {
      this.errors = {
        login: {
          email: '',
          password: '',
        },
        register: {
          name: '',
          email: '',
          password: '',
          password_confirmation: '',
        }
      }
    }
  },

  created() {
    this.resetErrors();
  }
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.13/vue.min.js"></script>

<div id="app">
  <button @click="resetErrors">
    Clear errors
  </button>

  <pre>
    {{ errors }}
  </pre>
</div>

 const result = data();
 for(const key in result.errors)
   result.errors[key] = "";
