Question

I’ve encountered code below and I’m not fully sure what it’s achieving.

I think it invokes the service ‘getvalues’ and passes some data into the service. On success the data returned is processed. Is this correct ?

 $.ajax({
      url: 'getvalues',
      data: ({urlVal : value}),
      success: function(data) {           
      }
    });

Did you try asking google?

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

url:

A string containing the URL to which the request is sent.

data:

Data to be sent to the server. It is converted to a query string, if
not already a string.

success(data, textStatus, jqXHR):

A function to be called if the request succeeds.
