need to check duplicate item in my table before insert date .But i am getting error while checking.Here is my code.I need to check whether the element already exist then return false If not then return true.And create a new entry

 function validationField() {
      db.transaction(getallTableCntend, errorCB);
    function getallTableCntend(tx) {
        tx.executeSql('SELECT * FROM CaseTable', [], queryexcecute, errorCB);
    function queryexcecute(tx, result) {
        var len = result.rows.length;
        for (var i = 0; i < len; i++) {
          if(result.rows.item(i).CaseName ==$('.caseName_h').val()){
            alert("Folder is already Exit.");

I am calling this like this.
$(document).on('click', '#AddButton', function() {
     isvalid = validationField();
    if (isvalid) {
            window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, onFileSystemSuccess, onFileSystemFail);
