Overriding A Jquery Core Function In Javascript - Getjson

I am trying to override the getJSON function in jQuery to provide additional params and then call the original getJSON. I am fairly unfamiliar with JavaScript and have scraped this

Solution 1:

You need to call $.getJSON, not $(foo).getJSON;

$.getJSON('ajax/test.json', function(data) {
    var items = [];
    alert('done');
});
