Understanding all parameters of jQuery's getJSON() method

Question

http://api.jquery.com/jQuery.getJSON/

displays the syntax and available parameters of getJSON() as:

jQuery.getJSON( url [, data ] [, success(data, textStatus, jqXHR) ] )

I am learning how to use this method and all the tutorials I have come across use:

jQuery.getJSON( "http://path/to/file.php", function(my_results) {

// do something with the my_results variable

}

I have got this working, but, in my newbie mind, such an example veers off from the available parameters pretty early, the only consistency that I can see being the URL parameter. And a function() is added however it is not shown in the 'available parameters' example.

Could anyone provide an example of a getJSON() method implementation where all the available parameters are used, with annotation about what each parameter is doing?

Is it enough or you need more details?

$.getJSON({
  url: '/file.php',
  data: {value1:"1",value2:"2"},
  success: function(data){ console.log(data);}
});

What is data: {value1:"1",value2:"2"} representing? Are those pairs that are being searched for in file.php and therefore they are the only pairs being returned? Or something else?

the values there are value-pair you will get on server value1 equal 1, they will send as get on php so you can do on server $_GET['value1'] and it will equals 1, makrk the question as resolved if it helped you

try this example to read RSS/ATOM feed from Google Feed Proxy http://jsfiddle.net/ck4Ct/

// Data object: RSS feed URL, number of entries to return, result format, API version
var data = {
    q: 'http://feeds.bbci.co.uk/news/video_and_audio/news_front_page/rss.xml'
    , num: 10
    , output: 'json'
    , v: '1.0'
};

// AJAX call to Google Feed API which converts ATOM/RSS feed to JSON
// Callback param added to url to do JSONP request
$.getJSON('http://ajax.googleapis.com/ajax/services/feed/load?callback=?'
            , data 
            , function (json) {
                alert(json.responseData.feed.entries[0].title)
            }
);
