    I don't know if you are using a Provided or Hosted AddIn, but try this;

     

    function getUrlParameter(name) {
    name = name.replace(/[\[]/, '\\[').replace(/[\]]/, '\\]');
    var regex = new RegExp('[\\?&]' + name + '=([^&#]*)');
    var results = regex.exec(decodeURIComponent(location.search));
    return results === null ? '' : decodeURIComponent(results[1].replace(/\+/g, ' '));
}

     

    Not get the stuff

     

    var itemID = getUrlParameter("ID");
    var versionID = getUrlParameter("VersionNo");
    if(itemID!= "" && versionID!= ""){
        $.ajax({
            url: _spPageContextInfo.webAbsoluteUrl + "/_api/lists/getbytitle('"+libraryName+"')/Items("+itemID+")/versions("+versionID+")?$select=FileLeafRef,FileRef",
            type: "GET",
            headers: {
                "Accept": "application/json;odata=verbose",
            },
            success: function (data) {
                var versionFileUrl = data.d.FileRef.replace(libraryName,"_vti_history/"+versionID+"/"+libraryName);
            },
            error: function (data) {
               
            }
        });
    }
