jQuery modal dialog and jqGrid

The following code could do what you need

$("#wics").click( function(){
    var grid = jQuery("#list10");
    var ids = grid.jqGrid('getGridParam','selarrrow');
    if (ids.length>0) {
        var names = [];
        for (var i=0, il=ids.length; i < il; i++) {
            var name = grid.jqGrid('getCell', ids[i], 'Name');
            names.push(name);
        }
        //alert ("Names: " + names.join(", ") + "; ids: " + ids.join(", "));
        $("#names").html(names.join(", "));
        $("#dialog-confirm").dialog({
            height:280,
            modal:true,
            buttons:{
                'Cancel': function(){
                    $(this).dialog('close');
                },
                'Confirm': function(){
                    //alert("Confirm");
                    $.ajax({
                        type: "POST",
                        url:  "/cpsb/unprocessedOrders.do",
                        data: { method: "releaseTowics",
                            orderNum: JSON.stringify(ids),
                            names: JSON.stringify(names)
                        },
                        dataType: "json",
                        success: function(msg){
                            alert(msg);
                        },
                        error: function(res, status, exeption) {
                            alert(res);
                        }
                    });
                }
            }
        });
    }
});

The exact solution of cause will depends on your requirement on the server side. You can try this (without ajax request) here http://www.ok-soft-gmbh.com/jqGrid/DataToMultiSelect2.htm. Select some items and click “Get Selected” button.
