Question

I have a code:

req = new AjaxAdapter;
req.dataType = 'json';

return req.query('GET', url, request, function(responseServer, status, xhr) {
        var json;
        json = responseServer.data;
        return response(json);
    }, function(jqXHR, textStatus, errorThrown) {
        var exception;
        exception = jQuery.parseJSON(jqXHR.responseText);
        return showError(exception);
    });

And I don’t understand it. So what is the query() function? I can’t find it in the jQuery documentation. See in my example that this function has 5 parameters:

• get
• url
• request
• function which return data (response)
• function which is call when is error

What is request? Where I can found documentation of the query() function?

This isn’t jQuery. As for what the query method does, look at its signature:

req.query( 'GET', url, request, function( responseServer, status, xhr )

It takes the post-type as the first parameter, a URL as the second, your request data as the third, and a callback function when the request completes.

Your callback returns the server’s response, a status code indicating the type of response, as well as the XHR object the query method used to issue the request.
