从Jquery函数返回时，对象属性发生变化

Question

Given the follow -

index.html

var jsonOut = $.getJSON("graph.json", function (jsonIn) {
            console.log(jsonIn);
            return jsonIn;
        });
console.log(jsonOut);

graph.json - contain a long JSON format .

The - console.log(jsonIn) output is -

Object {aaaa: Array[7], bbbb: Array[7], cccc: Array[7]}

But the - console.log(jsoOut) output is -

Object {readyState: 1, getResponseHeader: function, getAllResponseHeaders: function, setRequestHeader: function, overrideMimeType: function…}

Why does jsonIn and jsonOut seems different ? and how could I make jsonOut exactly same as jsonOut ?

Answer 1

jsonOut is the actual ajax object.

You dont need it (Usually ) inside the method.

Usually it is used by others who want to do something with this promise object. ( done , fail , always )

In short - you want jsonIn
