jQuery Grid Plugin - jqGrid

(function($){
        $.jgrid.extend({
            hashcontrol : function(p) {
                p = $.extend({
                    active : true
                },p || {});
                this.each(function(){
                    this.hash = true;
                    var ts = this;
                    var dt = ts.p.datatype.toLowerCase();
                    $.ajax($.extend({
                        url:ts.p.url,
                        type:ts.p.mtype,
                        dataType: dt ,
                        data: $.isFunction(ts.p.serializeGridData)? ts.p.serializeGridData.call(ts,ts.p.postData) : ts.p.postData,
                        complete: function(res,status) {
                            alert("123″);
                        }
                    }, $.jgrid.ajaxOptions, ts.p.ajaxSelectOptions || {} ));
                });
            }
