Jquery Easy UI access the data in the rows individually to make custom ajax calls

Question

In the demo file datagrid2.html of jquery-easyui-1.2.6, I am trying to access the data in rows through javascript so that I can use this to construct my ajax url to save UI changes on the server side.

The entire html code is as follows:

I am using easyui grid. This is easyui demo grid example code. Did you get data to grid? What do you want? Your question is very dirty. Please write clearly and ı can help you.

Firstly ı am using asp.net web services with ajax and ı am not using url(saveUrl,updateUrl etc) porperty of datagrid. You dont have to use url property of datgrid. You can use a function like this;

function savechanges(parmetervalue)
        {
            $.ajax({
                type: "POST",
                url: WEBSERVISURL + "/WEB_SERVIS_METHOD_NAME",
                data: "{WebServisParameterName:" + parmetervalue + "}",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function (msg) {
                    var data = eval("(" + msg.d + ")");
                },
                error: function (msg) {

                }                    
            });
        }

you can get savechanges funtion's "parmetervalue" parameter with datagrid "getSelected" method liks this;

var row = $('#yourgrid').datagrid('getSelected ');

and you can get all values of row;

for example ---- > row.ID , row.Name , row.SurName etc

and finally you can update your row like this;

savechanges(row.Name)

Yes, this is the sample code. Now the sample demo shows data in various rows, alright. Now I edit some data, so I would want to save the changed data in the server side also. For this I can make ajax calls. Now in order to form the url of an ajax I need the edited data to be sent in the url. How do I do that. I hope you understand this time.
@nixsix6: If you get your solution then you can mark this answer. By this way we more motivate to provide solutions. :)
Weird that I got my answer and both question and the answer are downvoted!
