Steps to clear the form in vue after the ajax request has been successfully submitted

Exploring Vue.js Web Form Validation with a Scenario

If you are interested in the vue-form validator library, it can be found at https://github.com/fergaldoyle/vue-form

For a demonstration of this scenario, check out the following jsfiddle link: https://jsfiddle.net/zfqt4yhq/51/

Questions:

  1. After submitting a form via AJAX, using dom's form.reset() method does not reset the form without errors. How can you properly handle resetting the form to its initial state without validation messages and CSS highlighting?

  2. In the provided jsfiddle example, how can you change the $submitted value in order to remove error classes?

    • To remove error classes, one condition is setting $submitted value to false. How can this value be changed?

    <field-messages name="name" show="$touched || $submitted" class="form-control-feedback">
       <div>Success!</div>
       <div slot="required">Name is a required field</div>
    </field-messages>

    • var vueformapp = new Vue({ ... });
    • vueformapp.$data.formstate.name.$touched = true // = false;
      • This changes the value.
    • vueformapp.$data.formstate.name.$submitted = ture // false;
      • This will not change the value.
  3. Is there a CSS hack that can be implemented to achieve a form reset in the given jsfiddle scenario?

Answer №1

It appears that the library is not resetting fields properly according to this GitHub issue

A user there recommends using the following code:

Object.keys(myFormState).forEach(k => {
  if (k[0] == '$') return;
  const field = myFormState[k];
  field._setPristine();
  field._setUntouched();
});

to mark the form as pristine and the fields as untouched. The creator mentioned that this feature will be added in the next release.

Alternatively, you could consider using vuelidate:

which includes a reset method. By the way, don't forget to reset the model in your tests like dfsq suggested.

Answer №2

Here is a simple method to clear a form after it has been successfully submitted.

  1. Begin by using JavaScript selectors to target the form element. If your page only has one form, this method works best.
const form = document.querySelector('form');
form.reset();
  1. If you are utilizing vee-validate, make sure to reset the validator to prevent any potential errors from occurring.
this.$validator.reset()

And that's all there is to it!

Answer №3

hide custom validation display tag using CSS

$('.error').hide();

Alternatively, you can use the following option:

 $('#formname').clearValidation();
