Actually i am fetching data from table in phone gap .But along with i also count the number of elements in another table .while fetching the value of i increase by own and getting an error..Item index is out of range.

function getallTableData(tx) {

   tx.executeSql('SELECT * FROM CaseTable', [], querySuccess, errorCB);
}

    function querySuccess(tx, result) {

        var len = result.rows.length;
        var countDoument=0
        $('#folderData').empty();
        for (var i = 0; i < len; i++) {

             alert(i)  // here value is i =0

             test1=result.rows.item(i).CaseName;



    Test1(test1,function(result_count){
    countDoument=result_count;   // here it count value
    alert(result_count+"result_count")  //alert is correct count value
    alert(i+"i"); //here i comes 1 why ? it should be 0

    $('#folderData').append(
                    '<li class="caseRowClick" id="' + result.rows.item(i).id + '" data-rel="popup" data-position-to="window">' + '<a href="#">' + '<img src="img/Blue-Folder.png">' + '<h2>' + result.rows.item(i).CaseName +countDoument+'</h2>' + '<p>' + result.rows.item(i).TextArea + '</p>' + '<p>' + result.rows.item(i).CaseDate + '</p>' + '</a>' +
                     '<span class="ctrl togg"><fieldset data-role="controlgroup" data-type="horizontal" data-mini="true" ><button class="edit button_design">Edit</button><button class="del button_design">Delete</button></fieldset><span>'+'</li>'
                    );

        });

       $('#folderData').listview('refresh');




    }


    }

    function Test1(test, callBack){
        var x;
        db.transaction(function (tx) {
                $yoursql = 'SELECT * FROM  "'+test+'" ';
                tx.executeSql($yoursql, [], function (tx, results) {
                    x = results.rows.length  + "TableName" + test;
                    callBack(x);
                });
        });
