    $siteurl = _spPageContextInfo.webAbsoluteUrl;
    var url = $siteurl+"/_api/web/lists/getbytitle('"+$listName+"')?$select=EnableVersioning"
    getData(url).done(function (data) {
        console.log(data.EnableVersioning);
        if(data.EnableVersioning)
        {
            alert("Versioning is enalbe");
