JSON.stringify返回日期的不同值

Question

i'm needing my json.stringify method to return me something like this:

//The code below is the same as JSON.stringify(new Date());
console.log(new Date().toJSON());

This returns me the following:

"/Date(1373046760480-0300)/"

which is fine, but it happens in certain scenarios that the same operation returns me this:

"2013-07-05T17:52:55.434Z"

which is not the expected result, and then i have to create string to have the expected result.

Does anybody know why this happens?

Answer 1

Unless someone accidentally (by using third party library) overwrites Date.prototype.toJSON the default output of JSON date is the latter:

Here's what could be (a non-standard implementation used by asp.net)

Date.prototype.toJSON = function(){ return "/Date(" + this.getTime() + ")/" }
