Exploring the power of Vue.js: Leveraging the onChange feature with TomSelect

How can I implement onChange with TomSelect in my code?

<TomSelect
            :disabled="disableForm"
              v-model="wareHouse.agent.id"
              :onChange="changeAgentData"
              class="w-full"
            >
              <option value="">No Agent</option>
              <template v-for="(business, indexKey) in company.agentCompanies">
                <option v-if="business.companyType.includes('Shipper')" :key="indexKey" :value="business.id">{{business.name}}</option>
              </template>
              
            </TomSelect>

The current implementation is not working as expected. The changeAgentData function is not being triggered. I have tried using @change, change, and changed but none of them worked.

Answer №1

Not quite sure what tomSelect is - whether it's a custom component you've created or from a library.

Regardless, in order for @change to work, you need to either set up this event yourself or ensure that the library has a trigger setup for it (refer to the documentation of the component you're using in that case).

If you're not clear on how to do this, you can use a watcher instead. Since your v-model uses wareHouse.agent.id, it seems like you want to take action when this property changes.

watch: {
 'wareHouse.agent.id'(newId) {
   this.changeAgentData(newId)
 }
}

Each time a user selects a new option, the v-model updates the value and triggers the watcher function. https://vuejs.org/guide/essentials/watchers.html#basic-example
