Question

After getting an HTTP response in the form a JSON file, how can I handle its plain content using jQuery?

I’ve done this before, but I just can’t figure out how right now.

I’m using this function to retrieve the JSON content.

var json = $.getJSON("test.json",  
   function(response){
           // do stuff
       }
);

Of course, I can handle the data contained in the JSON, but I’d like to handle and print its plain content, like this:

{"name": "Pepe","age" : "20"}

The following

alert(response);

Just gives me [object Object]

And this

alert(jQuery.parseJSON(json));

Just gives me null

I can’t seem to find the answer anywhere. I’m pretty new to all this, so I must be using the wrong search terms, because it looks like a trivial matter.

The callback to $.getJSON actually has 3 parameters. data, textStatus and jqXHR.

The jqXHR object contains a responseText property that contains the raw JSON string.

var json = $.getJSON("test.json",  
   function(response, status, jqXHR){
           // do stuff
           console.log(jqXHR.responseText);
       }
);
