What is the best approach for looping through an array fetched using Ajax in Vue?

Question

What is the best approach for looping through an array fetched using Ajax in Vue?

<div class="recipe-ingredients__container__functions paddings">
    <h5>Functions_</h5>
    <div class="foo" v-for="f in content.functions"></div>
</div>

When the HTML is rendered by Vue, the Ajax call is still in progress, so the content.functions data is not yet available. However, after the call is complete, I can see that the data has been correctly added using Vue Devtools in Chrome. Is there a simple way to trigger Vue to re-execute the v-for directive once the content.functions data becomes available?

Answer №1

To ensure your data remains up-to-date, initialize it as an empty array and only populate it once the AJAX request is successfully completed.

Here's an example:

data () {
  return {
    information: {
      details: []
    }
  }
},
created () {
  sendAjax().then(response => {
    this.information.details = response
  })
}
