javascript - jQuery getJSON save result into variable

I use getJSON to request a JSON from my website. It works great, but
I need to save the output into another variable, like
this:

var myjson=
            $.getJSON("http://127.0.0.1:8080/horizon-update", function(json) {


            });

I need to save the
result into myjson but it seems this syntax is not correct. Any
ideas?

Answer

You can't get value when calling
getJSON, only after
response.

var
            myjson;
$.getJSON("http://127.0.0.1:8080/horizon-update",
            function(json){
 myjson =
            json;
});
