按值排序json对象

I have a json object like below, how do I sort it using date?

json = {"date_hash":{"second_bleed":"2014-09-08","sixth_boost":"2014-10-28","first_boost":"2014-06-24","first_bleed":"2014-08-08","fifth_boost":"2014-09-30","fourth_bleed":"2014-11-03","second_boost":"2014-07-15","fourth_boost":"2014-09-02","third_bleed":"2014-10-06","primary_injection":"2014-06-02","third_boost":"2014-08-05"}}

I tried doing

json['date_hash'].sort(function(a, b){

});

Sort is not a function for json?

    The date_hash object is a JSON object which doesn't have an order (not sortable).

    You should try to use an array:

    {"date_hash": [
        {"name": "second_bleed", "date": "2014-09-08"},
       ....
       {"name": "sixth_boost", "date": "2014-09-28"}
    ]}
    

    and then you something similar to the function you're using to sort.

    function (a, b) {
        if (a.date < b.date) {
            return -1;
        } else if (a.date > b.date) {
            return 1;
        };
        return 0;
    }
