Search for a key in JSON with jQuery: $.inJSON

Find a key in JSON recursively with jQuery 1.4.2: $.inJSON

I needed a quick and dirty way to find a particular key's value in a JSON blob of relatively arbitrary structure. So I made the following jQuery 1.4.2 plugin, inJSON, along the same lines as $.inArray and $.grep

You can download it here: jquery.injson.js.

UPDATE: This plugin now has a project page on the jQuery plugin site.

Example of usage:

var zomg = {
    "a": "b",
    "c": {
        "d": "e",
        "a": [
            {
                "a": "barf"
            },
            {
                "z": "biz"
            }
        ]
    }
};

$.inJSON(zomg, "a");
["b", [Object { a="barf"}, Object { z="biz"}], "barf"]
