[Vuejs]-How to validate form in Vue?

0👍

I have not used Typescript, but ultimately, you’ll have to validate each model onSubmit. So, in the submit() function that you have, do preventDefault(), validate your fields and if all okay then go ahead actually do submit the form to the backend.

Do read the guide for general workflow: https://v2.vuejs.org/v2/cookbook/form-validation.html

Also, do check out Vuelidate and VeeValidate which are simple validation frameworks for VueJS.

p.s.: see: using Vuelidate with Typescript issue first for good pointers.
