将数组中的对象数组添加到 JSON 中

Question

I had this JSON:

"event": [
{
  "timestamp": "2016-10-02T11:37:31.2300892-03:00",
  "revenue": 120.0,
  "transaction_id": "3409340",
  "store_name": "BH Shopping",
  "products": []
}

And this Object Array:

[ { name: 'Blue Shirt', price: 100 },
  { name: 'Nike Shoes', price: 150 } ]

How can I add the Object Array into the products Array inside the JSON using Javascript?

Answer 1

Please check this solution of adding objects to object property:

 var jsonStr = '{"event": {"timestamp": "2016-10-02T11:37:31.2300892-03:00", "revenue": "120.0", "transaction_id": "3409340", "store_name": "BH Shopping", "products": []}}'; var obj = JSON.parse(jsonStr); obj['event']['products'].push({"name":"Blue Shirt","price":"100"}); obj['event']['products'].push({"name":"Nike Shoes","price":"150"}); jsonStr = JSON.stringify(obj); console.log(jsonStr);

From the look of it, event is a JSON Array on its own so to target the first one you will have to pict JSON Object at index 0 .

var eventObject = event[0];

Now the products is an array and you can push staff into it by iterating over your Object Array

objectArray.forEach(function(object){
    //the object is each array item
    eventObject.products.push(object);
});
