What is the best way to verify Vue.js fields that have been pre-filled from a database source?

Looking to validate the inputs from a form using vuejs. Also, if the data is pre-populated, I want the inputs to switch to readonly mode.

<input type="number" name="cf_962" class="form-control" v-model="fillProfile.cf_962" step="0.1" :readonly="(fillProfile.cf_962>0.00) ? true : false">

The current issue I'm facing is that whenever I input a value, if it's greater than 0, the input becomes read-only automatically, which is not desired. How can I achieve this in vuejs 2? Thanks for your help.

Answer №1

If you want to achieve this task effortlessly, consider using the v-once directive.

<input type="number" name="cf_962" class="form-control" v-model="fillProfile.cf_962" step="0.1" :readonly="(fillProfile.cf_962>0.00) ? true : false" v-once>

Referencing the documentation:

It is possible to make one-time interpolations that do not update when data changes by utilizing the v-once directive. However, be aware that this will also impact any other bindings on the same node.

The v-once directive allows you to establish the readonly attribute for inputs with pre-filled data, while excluding inputs without pre-filled data. This behavior occurs only once, so subsequent input changes will not affect the readonly status anymore.
