Is there a way to automatically validate v-forms inside a v-data-table when the page loads?

In my data entry form, I have utilized a v-data-table with each column containing a v-form and v-text-field for direct value updates. My goal is to validate all fields upon page load to identify any incorrect data inputs. However, I am facing challenges in achieving this comprehensive validation on load. I attempted to add a ref for each form column and then call the validate() function within the mounted() function, but only the first row gets validated upon page load. Additionally, I experimented with validating the form during the form load event (e.g. v-form @load="this.validate()"). How can I adjust my code to ensure that the entire data table is validated when the page loads?

                type="text"
                class="justify-center"

          </v-row>
        </v-container>
      </template>
    </v-data-table>
</v-card>

Typescript

mounted() {
    (this.$refs.disbursable_form as any).validate();
    (this.$refs.pending_transfer_form as any).validate();
  }

Answer №1

After much thought, I finally found a solution to the problem. I decided to move the <v-form> element outside of the <v-data-table> and implemented a two-second delay before calling the validate() function.

Code

Template

<v-card max-width="95%">
    <v-card-title>Collateral</v-card-title>
    <v-form ref="collateral_form">
        <v-data-table
          :items="this.$store.state.CurrentInstrumentDetails.collateral"
          :headers="headers"
        >
          .
          .
          .
        </v-data-table>
    </v-form>
</v-card>

Typescript

mounted() {
  setTimeout(() => {
    (this.$refs.collateral_form as any).validate();
  }, 2000); 
}
