sort a json file with 2 entries

问题

I have a json file like

 var data = {
     "list":[

{
    "g": "zas",
    "e": "wef"
},
{
    "g": "abc",
    "e": "ew"
},
{
    "g": "wee",
    "e": "asd"
},.....

How do I sort the entries w.r.t "g" so that I get abc then wee and then zas.... I want the sort changes permanently in the json file

In JavaScript, you can use a custom comparator function to sort an array like so:

data.list.sort(function (a, b)
{
    return a.g > b.g ? 1 : a.g < b.g ? -1 : 0
});

Array.sort @ MDC
