Filtering jqGrid by multiple conditions at client side

Question

I have a jqGrid with some records and want to filter the records based on multiple conditions.

For instance, if there are three columns, Name, Age and City and I want to filter the grid on the following condition:

Name = "Mark" and Age = 25 and City = 'NY'

the following code works fine-

 var grid = jQuery("#memberDetails");
 var postdata = grid.jqGrid('getGridParam', 'postData');

 var filterArray = new Array();
 var filterConidtion; 

 filterConidtion = new Object();
 filterConidtion.field = "name";
 filterConidtion.op = "eq";
 filterConidtion.data = "Mark";
 filterArray.push(filterConidtion);

 filterConidtion = new Object();
 filterConidtion.field = "Age";
 filterConidtion.op = "eq";
 filterConidtion.data = "25";
 filterArray.push(filterConidtion);

 filterConidtion = new Object();
 filterConidtion.field = "City";
 filterConidtion.op = "eq";
 filterConidtion.data = "NY";
 filterArray.push(filterConidtion);

 jQuery.extend(postdata, {
        filters: {
            "groupOp": "and",
            "rules": filterArray
        }
    });

 grid.jqGrid('setGridParam', {
            search: true,
            postData: postdata
    });

 grid.trigger("reloadGrid", [{
        page: 1
    }]);

but I am not sure how to make the following filter work:

Name = "Mark" and Age = 25 and (City = 'NY' OR City = 'FL')

The groupOp works either on AND or on OR condition, not sure how to embed a sub condition within the groupOp

Thanks.

Format of filters are described in the documentation. To implement more complex searching criteria one can use groups property of filters. The corresponding code could be about the following:

var $grid = $("#memberDetails");

$.extend($grid.jqGrid("getGridParam", "postData"), {
    filters: JSON.stringify({
        groupOp: "AND",
        rules: [
            { field: "Name", op: "eq", data: "Mark" },
            { field: "Age",  op: "eq", data: "25" }
        ],
        groups: [
            {
                groupOp: "OR",
                rules: [
                    { field: "City", op: "eq", data: "NY" },
                    { field: "City", op: "eq", data: "FL" }
                ],
                groups: []
            }
        ]
    })
});
$grid.jqGrid("setGridParam", {search: true})
     .trigger('reloadGrid', [{current: true, page: 1}]);
