Rendering a Vue select list before receiving data from a Meteor callback

I am currently facing an issue with populating my events array from a meteor call so that it appears in a select list. The 'get.upcoming' Meteor function returns an array of JSON objects, but it seems like the select list is being rendered before the event array is fully populated.

Is there a way to update or delay the rendering of the select box until after the events array has been completely populated?

<template>
    <div class="container">
        <select v-model='eventId'>
            <option v-for='event in events'>{{JSON.stringify(event)}}</option>
        </select>
    </div>
</template>

<script>
    export default {
        data() {
            return {
                eventId: "",
                events: [],
            }
        },

        created() {
            this.getItems();
        },

        methods: {
            getItems() {
                console.log("retrieving items");
                Meteor.call('get.upcoming', (err, res) => {
                    if (err) {
                        console.log(err);
                    } else {
                        this.events = res;
                        console.log(this.events);
                    }
                })
            }
        }
    }
</script>

Answer №1

Remember to save the response of your Meteor call by using this.events = res; within the callback function.

Ensure you can access the Vue instance by utilizing an arrow function for your callback and referencing it with this.

fetchData() {
  console.log('Fetching data');
  Meteor.call('retrieve.data', (error, result) => {
    if (error) {
      console.log(error);
    } else {
      this.events = result;
      console.log(this.events);
    }
  })
}

  1. To update the select menu, simply updating the data array that is connected to it will trigger a re-render of the select box. Any variables declared in the data() method within a Vue template are accessible as class variables once the page loads and can be bi-directionally bound to components.

if (!error) this.events = newEvents

  1. If you want to display the select box only after receiving JSON objects from a Meteor method and loading them into the events array, use a conditional binding in Vue to show the HTML element once the data is available.

<template>
  <select v-if="dataLoaded"> </select>
</template>

<script>
return {
  data() {
    return {
      dataLoaded: false
    }
  }

  asyncMethod() { this.dataLoaded = true; }
};
</script>
