[FIXED] how to get data from JSON file in Vue.js?

Issue

I have 'modified_data.json' JSON file which has this structure.

{
"data": [
    [
        {
           "account_id": "  "
           "account_name": "   "
        },
        {
           "account_id": "  "
           "account_name": "   "
        },          
        {
           "account_id": "  "
           "account_name": "   "
        },          
        {
           "account_id": "  "
           "account_name": "   "
        }
     ],
     [
        {
           "account_id": "  "
           "account_name": "   "
        },
        {
           "account_id": "  "
           "account_name": "   "
        },
        {
           "account_id": "  "
           "account_name": "   "
        }
     ],
     [
        {
           "account_id": "  "
           "account_name": "   "
        },
        {
           "account_id": "  "
           "account_name": "   "
        },
        {
           "account_id": "  "
           "account_name": "   "
        }
      ]
   ]
}

I want to get first object's account_name from each array...

Does anyone can give me a solution??

Now I'm using Vue.js to display it, I could get each data with python, but Vue.js is not familiar with me yet... Kindly help me :)

Solution

You can use a computed property that would reactively take account_name property of the first object of every array:

const data = {
  "data": [
    [
      {
        "account_id": "11",
        "account_name": "name11"
      },
      {
        "account_id": "12",
        "account_name": "name12"
      },
      {
        "account_id": "13",
        "account_name": "name13"
      },
      {
        "account_id": "14",
        "account_name": "name14"
      }
    ],
    [
      {
        "account_id": "21",
        "account_name": "name21"
      },
      {
        "account_id": "22",
        "account_name": "name22"
      },
      {
        "account_id": "23",
        "account_name": "name23"
      }
    ],
    [
      {
        "account_id": "31",
        "account_name": "name31"
      },
      {
        "account_id": "32",
        "account_name": "name32"
      },
      {
        "account_id": "33",
        "account_name": "name33"
      }
    ]
  ]
}


new Vue({
  el: '#demo',
  data() {
    return {
      data: data.data
    }
  },
  computed: {
    firstAccountNames() {
      return this.data.map(dataSet => dataSet[0].account_name)
    }
  }
})

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="demo">
  <ul>
    <li v-for="name in firstAccountNames">
      {{ name }}
    </li>
  </ul>
</div>
