Question

I have a json object with the following structure:

[
{
"filters": [
    {
        "name": "category",
        "list": [
            {
                "category-abc": {
                    "title": "abc",
                    "number": "2"
                }
            },
            {
                "category-def": {
                    "title": "def",
                    "number": "1"
                }
            }
        ]
    },
    {
        "name": "topic",
        "list": [
            {
                "topic-abc": {
                    "title": "abc",
                    "number": "6"
                }
            },
            {
                "topic-def": {
                    "title": "def",
                    "number": "5"
                }
            }
        ]
    },
}
]

The list is actually much longer, with many name | list pairs. I am looking to grab each list as I iterate along an array of list names, but don’t want to walk that list every time, so I want to grab the list by name.

Something like this:

filters['topic'][0].title

But that won’t work, as there’s the “name” key there. Is there any way to do this without conditionals?

I think this is what you want (it assumes data contains the original JSON object):

var filters = [];
foreach (var subitem in data[0].filters) {
  filters[subitem.name] = subitem.list;
}
