javascript to check css element

[benanderson_475]

If you want to do a kind of AND/OR gate then you need this. Change group addresses as needed and you can change && (AND) to || (OR).

Code:

1234567891011121314151617

$(function(){    var v1 = false, v2 = false;    function set() {       $(".hidebyknx").toggleClass("hide", v1 && v2);    }    grp.listen('1/1/1', function(object, state) {       v1 = object.value;       set();    }, true);    grp.listen('1/1/2', function(object, state) {       v2 = object.value;       set();    }, true); });

Yes this is what i am after, works well many thanks, 

Also how can i request the value for both obj on page load? something like the below? grp.write() works for me but not grp.read() also is there a list of functions that are available in the custom js to interact with objects from the vis etc.

Code:

12345

  $(document).ready(function() {     grp.read('1/1/1')     grp.read('1/1/2')      });
