Conditionally add @submit.prevent to a form in Vue.js

I'm trying to conditionally prevent HTML form submission using @submit.prevent. I have a generic form model that looks like this (minimized a bit):

<v-form v-model="valid">
   <div>
      <div v-for="(field, i) in fieldConfig" :key="`model-form-`+i">
         <fe-label v-if="field.label">{{field.label}}</fe-label>
         <component 
            :is="field.component" 
            v-bind="field.attrs" 
            v-model="item[field.field]"
          />
       </div>
   </div>
</v-form>

Called from a parent:

<model-form
   idProperty="id"
   @done="finishRename"
   model="myModel"
   :fieldConfig="fieldConfig"
   :htmlSubmit="false"
/>

I've seen some similar things in my searching but nothing quite right, and I'm pretty raw when it comes to Vue. Any help is appreciated. Thanks!

As Andy pointed out, @submit.prevent should not be used for conditional form submission because the .prevent modifier automatically calls Event.preventDefault().

To conditionally call it, you'd have to remove the .prevent modifier, and evaluate the htmlSubmit flag beforehand within the event handler:

<v-form @submit="onSubmit" action="https://example.com">

export default {
  methods: {
    onSubmit(e) {
      if (!this.htmlSubmit) {
        e.preventDefault() // don't perform submit action (i.e., `<form>.action`)
      }
    }
  }
}
