javascript - Sorting json object by value -

-

i have json object below, how sort 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 not function json?

the date_hash object json object doesn't have order (not sortable).

you should try use array: 

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

and similar function you're using sort.

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