var listItemEnumerator = collListItem.getEnumerator();


while (listItemEnumerator.moveNext()) {
    var oListItem1 = listItemEnumerator.get_current();

    {

     while (listItemEnumerator.moveNext()) {
        var oListItem = listItemEnumerator.get_current();
            listTitle.push(oListItem.get_item('Title'));
