How to build an array from a jSon object

Question

I am trying to build 2 arrays from JSON arrays.

{
    "2015-03-24": {
        "bind": 0,
        "info": "",
        "notes": "",
        "price": "150",
        "promo": "",
        "status": "available"
    },
    "2015-03-25": {
        "bind": 0,
        "info": "",
        "notes": "",
        "price": "150",
        "promo": "",
        "status": "available"
    },
    "2015-03-26": {
        "bind": 0,
        "info": "",
        "notes": "",
        "price": "150",
        "promo": "",
        "status": "available"
    },
    "2015-03-27": {
        "bind": 0,
        "info": "",
        "notes": "",
        "price": "100",
        "promo": "",
        "status": "available"
    },
    "2015-03-28": {
        "bind": 0,
        "info": "",
        "notes": "",
        "price": "100",
        "promo": "",
        "status": "available"
    },
    "2015-03-29": {
        "bind": 0,
        "info": "",
        "notes": "",
        "price": "100",
        "promo": "",
        "status": "available"
    },


    "2015-04-10": {
        "bind": 0,
        "info": "",
        "notes": "",
        "price": "",
        "promo": "",
        "status": "booked"
    },
    "2015-04-11": {
        "bind": 0,
        "info": "",
        "notes": "",
        "price": "",
        "promo": "",
        "status": "booked"
    },

    "2015-05-01": {
        "bind": 0,
        "info": "",
        "notes": "",
        "price": "",
        "promo": "",
        "status": "unavailable"
    },
    "2015-05-02": {
        "bind": 0,
        "info": "",
        "notes": "",
        "price": "",
        "promo": "",
        "status": "unavailable"
    },
    "2015-05-03": {
        "bind": 0,
        "info": "",
        "notes": "",
        "price": "",
        "promo": "",
        "status": "unavailable"
    },


}

This is the jSon array, so I want to build 2 arrays.

1 array holding only keys (in this case the date) of those element where status=='booked' nOR status=='unavailable' and build it in jQuery array like this

var array = ['2015-03-19', '2015-03-20', '2015-03-21', '2015-03-22', '2015-03-23', '2015-03-24', '2015-03-25', '2015-03-26', '2015-04-07', '2015-04-08', '2015-04-09', '2015-04-10'];

Another is building another array with the dates of those days where status=='available' AND price > '100$'

var array2 = [ '2015-03-25', '2015-03-26', '2015-04-07', '2015-04-08'];

How can I achieve this on with jQuery?

Answer 1

If j is your json:

var a1 = [];
var a2 = [];
$.each( j, function( key, ob ) {
    if(ob.price > 100 && ob.status == 'available'){
        a1.push(key);
    }
    if(ob.status == 'booked' || ob.status == 'unavailable'){
        a2.push(key);
    }
});
console.log(a1);
console.log(a2);

Yields:

["2015-03-24", "2015-03-25", "2015-03-26"]
["2015-04-10", "2015-04-11", "2015-05-01", "2015-05-02", "2015-05-03"]
