v-for to JSON complex

Related searches

Do you know how I can go through the next JSON with VUE? I do not understand how to do it since it has keys that von V-FOR can not access:

[
    {
        "Lavandería": {
            "id": 1,
            "name": "Lavandería",
            "img": "rinse.png",
            "Servicios": [
                {"model":"Sentra", "doors":4},
                {"model":"Maxima", "doors":4},
                {"model":"Skyline", "doors":2}
            ]
        },
        "Tintorería": {
            "id": 2,
            "name": "Tintorería",
            "img": "shirt-2.png",
            "Servicios": [
                {"model":"Sentra", "doors":4},
                {"model":"Maxima", "doors":4},
                {"model":"Skyline", "doors":2}
            ]
        },
        "Planchado": {
            "id": 3,
            "name": "Planchado",
            "img": "iron.png",
            "Servicios": [
                {"model":"Sentra", "doors":4},
                {"model":"Maxima", "doors":4},
                {"model":"Skyline", "doors":2}
            ]
        },
          "Otros": {
            "id": 4,
            "name": "Otros",
            "img": "wring.png",
            "Servicios": [
                {"model":"Sentra", "doors":4},
                {"model":"Maxima", "doors":4},
                {"model":"Skyline", "doors":2}
            ]
        }
    }
]

I need to access the id and image of each one in the first part to later be able to access the "Services".

I am dealing with V-FOR in this way:

v-for="item in services" :key="item.id"

But I can not even access each ID. I have made a console.log in this way and I see the data but I do not understand how to do with VUE: console.log(this.services[0].Lavandería.id);

You can iterate also an object:

<ul v-for="(service, index) in services" :key="index">
  <li v-for="(item, key) in service" :key="key">{{key}}: {{item}}</li>
</ul>

JsFiddle

If you have only one object in the array, use directly services[0] instead of the first v-for.

You need to understand your JSON structure.

If in case you only want to access all services from each object and just display them linearly, you can map the service array into a flat array.

Using your data as a sample -- which is an array containing an object with multiple root level keys

In your template

v-for="item in getServices(arr)"

In your vue model

new Vue({
    //....
    methods: {
        //...
        getServices(arr){
           let obj = arr[0];
           return [].map.call(Object.keys(arr[0]), k => {
                   return obj[k].Servicios
               }).reduce((acc, val) => acc.concat(val));
        }

    }
})

Use the FOR JSON clause to simplify client applications by delegating the formatting of JSON output from the app to SQL Server. When you use the FOR JSON clause, you can specify the structure of the JSON output explicitly, or let the structure of the SELECT statement determine the output.

  • I'm guessing in your case that services is equal to the array which is wrapping the object... you'll need to make it equal to array[0] instead of just array. Just assign the variable to the actual object you want to loop & you should be fine... v-for="item in services[0]" :key="item.id" ?
