Custom "Add Data" - how to post data to PHP server?

I have the following PHP script:

$OperMode = $_POST['oper']; 
switch($OperMode) {
/* [...] */
case 'ManAdd':
            // get data
            $Firma = $_POST['Name'];
            $Adresse = $_POST['Address'];
            $PLZ = $_POST['PLZ'];
            $Ort = $_POST['Ort'];
            $TelNr = $_POST['TelNr'];
            /* [...] */
            // save data to SQL database with adapted strings
            $Insert ="INSERT INTO adresse (Nachname, Vorname, Strasse, Hausnummer, Postleitzahl, Ort, Telefonnummer) VALUES('$Nachname', '$Vorname', '$Strasse', '$Hausnummer', '$PLZ', '$Ort', '$TelNr')";
            if(mysql_query($Insert)) {
                echo "Eintrag erfolgreich."; // Successful
            } else {
                die("Eintrag nicht erfolgreich!<br>Telefonnummer existiert bereits!"); // Not successful
            }               
            break;

Now I'd like to save selected rows from a jqGrid with the PHP script above. Here is the code of the grid and a custom button:

$("#ResultGrid")
                .jqGrid({
                    colNames:['Firma', 'Adresse', 'Postleitzahl', 'Ort', 'Telefonnummer'],
                    colModel:[
                    {name:'Firma', index:'Firma', width:175, searchable:false},
                    {name:'Adresse', index:'Adresse', width:160, searchable:false},
                    {name:'Postleitzahl', index:'Postleitzahl', width:100, searchable:false, sorttype:'int'},
                    {name:'Ort', index:'Ort', width:150, searchable:false},
                    {name:'Telefonnummer', index:'Telefonnummer', width:160, searchable:false}
                    ],
                    datatype: "clientSide",
                    editurl:'Edit.php',
                    height: 'auto',
                    loadonce: true,
                    multiselect: true,
                    pager:'#ResultPager',
                    rownum:-1,
                })
                .navGrid('#ResultPager', {view:false, edit:false, add:false, del:false, search:false, refresh:false} )
                .navButtonAdd('#ResultPager', {title:"Adresse ins Addressbuch übernehmen", buttonicon:"ui-icon-disk", caption:"Speichern", onClickButton:function(){
                    if($("#ResultGrid").getGridParam('selrow') == null || $("#ResultGrid").getGridParam('selrow') == undefined) {
                        $("#Dialog").html("<p><span class=\"ui-icon ui-icon-info\" style=\"float:left; margin:0 7px 20px 0;\"></span>Bitte eine Adresse ausw&auml;hlen!</p>");
                        $("#Dialog").dialog("option", "title", "Hinweis:");
                        $("#Dialog"开发者_运维百科).dialog("open");
                    } else {
                        var ID = $("#ResultGrid").getGridParam('selrow');
                        var AddressRow = $("#ResultGrid").getRowData(ID);                       
                        // The data to be stored:
                        var NameLine = AddressRow.Firma;
                        var AddressLine = AddressRow.Adresse;
                        var ZipCode = AddressRow.Postleitzahl;
                        var City = AddressRow.Ort;
                        var PhoneNumber = AddressRow.Telefonnummer;

                      $.ajax({
                    type: 'POST',
                    url: 'Edit.php',
                    dataType: // ???
                    data: // ???                    
                        });                   
                    }
                }})

I need to post the operation mode "ManAdd" (oper = "ManAdd") and the address to the server. In this case which datatype is needed and how is the data option constructed?

It seems to me that it would be enough to set no dataType and to use as the data parameter something like following:

data: {oper: 'ManAdd', Name: NameLine, Address: AddressLine, PLZ: ZipCode,
       Ort: City, TelNr: PhoneNumber}
