Explain some javascript/jquery code [closed]

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) {           
      }
    });

Because it is a valid question that could be answered with just a little research — mcgrailm

"Why all the downvotes" Because the docs explain it as linked by multiple people and people probably think you did not put the effort into researching before asking. — epascarello

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.

calls the getvalues url and passes the parameters urlVal to that page, then it gets the returns data from getvalues, but does not output it.

Exactly.

It makes a GET request to 'getvalues' url (relative to current page),
sending value of value variable as urlVal parameter,
and on success it does nothing (empty function).

$.ajax makes a GET request by default, not POST.
