You could access the client/js visual query object and data by its PHP name:

<?php
    VisualQuery::create(array(
        "name" => "visualquery1",
        ...
    )):
?>
<script>
    var visualQueryObj = visualquery1;
    var visualQueryData = visualquery1_data;
    var visualQueryCurrentValue = visualquery1_data.value;
</script>

It should be noted that visualquery1_data.value represents the latest submitted or initialized visual query value, not the real time value that hasn't been submitted yet. In the next releases of VisualQuery package we will try to provide a method to provide real time values of the visual query object.

1 . At the moment VisualQuery hasn't had language files yet so you could open the files SelectTables.php, SelectFilters.php, etc directly to change the labels yourself. We will add language files in the future releases of VisualQuery.

2 . Would you please post some code and/or screenshot for us to better understand the problem. Thanks!
