Accessing nested JSON with Vue

Question

I'm trying to access nested JSON in an array using Vue for a basic search. Each school is wrapped in a "hit" array, so instead of returning each school's data, it's thinking there's only 1 result of "hit." I'm certain I just need to add hit to each instance of schools, but I'm not sure how. Thank you for any help.

My main app file:

<template>
    <div class="app search">
        <!-- Search header -->
        <header id="searchHeader" class="search--header py-2 py-md-4">
            <div class="container">
                <div class="input-group">
                    <!-- Type filter -->
                    <TypeFilter v-model="type"/>

                    <!-- Location filter -->
                    <!--<LocationFilter />-->

                    <!-- Search box -->
                    <SearchBox v-model="searchTerm"/>

                    <!-- More filters -->
                    <!--<div class="dropdown checkbox-dropdown mx-2">
                        <button class="btn btn-lg btn-white py-3 px-4 dropdown-toggle" type="button" id="dropdownMenuButtonFilters" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">More Filters</button>
                        <div class="dropdown-menu" aria-labelledby="dropdownMenuButtonFilters">
                        </div>
                    </div>-->

                    <!-- Search button -->
                    <button v-on:click="searchSubmit(searchTerm)" class="btn btn-lg btn-white ml-2 px-4 search-submit">Search</button>
                </div>

                <!-- Active filters (hidden for v0) -->
                <!--<div class="search--header--filters mt-3">
                    <span class="badge">Filter</span>

                </div>-->
            </div>
        </header>

        <!-- Main results -->
        <div class="container">
            {{ message }}

            <!-- Result count and show/sort -->

Answer 1

To access of each school's name, you should access it like this:

const hit = this.schools[0].hit;

Then you iterate on the property hit

hit.forEach(function(el) {
  console.log(el.title);
});

To do that, may be you should flatten the property schools in a computed property to make it easier to access later.

To declare the flattened variable, you can declare it in the computed property:

computed: {
 // other properties ...
 flattenedSchools: function () {
      const schools = [];
      if (this.schools && this.schools.length) {
          // up to you to check if hit exist and has values
          this.schools[0].hit.forEach(function(el) {
            schools.push((el.title);
          });
      }
      return schools;
   },
},

To access to flattenedSchools, just use this.flattenedSchools and iterate on it.
