Delete specified array from firebase database

Question

I would like to delete the item2 if i choose the delete button of item2.

 {
      "items" : {
        "category1" : {
          "item" : {
            "0" : {
              "name" : "item1",
            },
            "1" : {
              "name" : "item2",
            },
            "2" : {
              "name" : "item3",
            }
          }
        },
        "category2" : {
          "item" : {
            "0" : {
              "name" : "item1",
            }
          }
        }
}

I tried with this code:

removeItem: function (item, category) {
        db.ref('items').child(category1).child('item').child(item['.key']).remove()
      },

Anybody see what i missing?

Try doing something like this:

removeItem: function (category, itemId) {
        db.ref('items').child(category).child('item').child(itemId).remove()
      }

Considering: category is "category1" and itemId is "1".

So, the function will be called as: removeItem("category1", "1") // to delete "item2"
