TimeStamp in getjson request?

Question

JavaScript

I make a request via $.getJSON and the response is null because js automatically adds &_=1518267865683(TimeStamp) to the end of the request.
How to turn it off?

Answer 1

In general, it is easy to google.

$.ajaxSetup({
           'cache':false
});

But I doubt that you have null because of the additional timestamp parameter, I think that's not the point.
