Assuming you have some kind of object that contains a Date
:
var o = { d : new Date() };
You can override the toJSON
function of the Date
prototype. Here I use moment.js to create a moment
object from the date, then use moment’s format
function without parameters, which emits the ISO8601 extended format including the offset.
Date.prototype.toJSON = function(){ return moment(this).format(); }
Now when you serialize the object, it will use the date format you asked for:
var json = JSON.stringify(o); // '{"d":"2015-06-28T13:51:13-07:00"}'
Of course, that will affect all Date
objects. If you want to change the behavior of only the specific date object, you can override just that particular object’s toJSON
function, like this:
o.d.toJSON = function(){ return moment(this).format(); }
