    this.collListItem = oList.getItems(camlQuery);

    clientContext.load(collListItem);
    clientContext.executeQueryAsync(
        Function.createDelegate(this, this.onQuerySucceeded),

function onQuerySucceeded(sender, args) {
    var listItemInfo = '';
    var listItemEnumerator = collListItem.getEnumerator();

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

            var Title = oListItem.get_item('Title') ;
