How to highlight input content via function?

Question

Vue.js

Good afternoon, I have inputs in the loop.

<input
v-bind::class="IfCountUP(quantity, max_quantity)"
:id="'QID_'+id" type="text"
min="1"
v-bind:max="max_quantity"
v-bind:value="quantity">

How to highlight the value value by condition?
If quantity > max_quantity Is it
possible to pass THIS of this element to the IfCountUP function? After all, $event.target cannot be passed there, since there is no event.

Answer 1

Is there any motivation for not using v-model? - now everything looks as if you are putting sticks in your own wheels out of the blue. Still elementary, for example .
