my jqgrid configuration is like that..

jQuery('#tableGrid').jqGrid({    
       //url:'../admspanel/maingridrptcustcomplain.php',
    datatype: "xml",
    height: 470,
    width:680,
    mtype:"POST",
       colNames:['Code','Date','Username','Customer Name','Contact Person','Menu','Description'],
       colModel:[
           {name:'code',index:'KdComplain',width:80,align:"left"},
           {name:'dateComp',index:'TglInput',width:80,align:"left",formatter:'date',formatoptions: {srcformat:'Y-m-d',newformat:'M d,Y'}},
        {name:'username',index:'Username',width:120,align:"left"},
           {name:'custName',index:'CustomerName',width:200,align:"left"},
        {name:'contact',index:'ContactPerson',width:150,align:"left"},
        {name:'menu',index:'Menu',width:180,align:"left"},
        {name:'desc',index:'Description',width:350,align:"left"}
       ],
       rowNum:100,
       //rowList:[10,20,30],
       pager: '#navGrid',
       sortname: 'KdComplain',
    shrinkToFit:false,
    viewrecords: true,
    sortorder: "asc",
    reloadGrid:false,
    //rownumbers:true,
    //rownumWidth: 40,
    //gridview: true,
    scroll: 1,
    reloadGrid:false,
    caption: "Report Customer Complaint"
});

i have a function that convert that grid to excel

here is my function :

function PrintExcel(DateFrom,DateTo,User) {    
    //var data = new Array();
    var count = $("#tableGrid").jqGrid('getGridParam','records');
    var caption = $("#tableGrid").jqGrid('getGridParam','caption');    
    var colnames = $("#tableGrid").jqGrid('getGridParam','colNames');
    var colmodel = $("#tableGrid").jqGrid('getGridParam','colModel');
    var ids = $("#tableGrid").getDataIDs();
    
    codeComp = "";
    dateComp = "";
    usergrid = "";
    cust = "";
    contact = "";
    menu = "";
    desc = "";
    headernames = "";
    headerwidth = "";
    
    for (var i = 0; i < colnames.length; i++) {
        headernames = headernames+"|"+colnames[i];
    }
    
    for (var i = 0; i < colmodel.length; i++) {
        headerwidth = headerwidth+"|"+(colmodel[i].width/10+3);
    }
    
    if(count == 0) return false;    
    for (var i = 0; i < ids.length; i++) {
        codeComp = codeComp+"|"+$("#tableGrid").getCell(ids[i],'code');
        dateComp = dateComp+"|"+$("#tableGrid").getCell(ids[i],'dateComp');
        usergrid = usergrid+"|"+$("#tableGrid").getCell(ids[i],'username');
        cust = cust+"|"+$("#tableGrid").getCell(ids[i],'custName');
        contact = contact+"|"+$("#tableGrid").getCell(ids[i],'contact');
        menu = menu+"|"+$("#tableGrid").getCell(ids[i],'menu');
        desc = desc+"|"+$("#tableGrid").getCell(ids[i],'desc');        
    }
    codeComp = codeComp.substring(1);
    dateComp = dateComp.substring(1);
    usergrid = usergrid.substring(1);
    cust     = cust.substring(1);
    contact  = contact.substring(1);
    menu     = menu.substring(1);
    desc     = desc.substring(1);
    headernames = headernames.substring(1);
    headerwidth = headerwidth.substring(1);    
        
    window.location = 'doPrintExcel-rptcustcomplain.php?cap='+caption+'&cou='+count+'&hn='+headernames+'&hw='+headerwidth+'&cc='+codeComp+'&dc='+dateComp+'&ug='+usergrid+'&cs='+cust+'&ct='+contact+'&mn='+menu+'&de='+desc+'&f='+DateFrom+'&t='+DateTo+'&u='+User;
}

when i click the Print button, i call PrintToExcel function like that

PrintExcel($('#txtDateFrom').val(),$('#txtDateTo').val(),$('#cboUser :selected').text());

on doPrintExcel-rptcustcomplain.php, i'm split my variabel to array..

and then i print all my variabel to excel

i know is not a good way..

it's work for a small data..

if a grid have a big data, it's work not good because the url that i passing is to long

is there any best way convert to excel?

Best Regards,
