js script:

<script src="{{ asset('js/fullcalendar') }}/fullcalendar.js"></script>  <script src="{{ asset('js/bootstrap.js') }}"></script>  <script type="text/javascript">      $(document).ready(function() {            var base_url = '{{ url('/') }}';                          $('#bootstrapmodalfullcalendar').fullcalendar({        weekends: true,        header: {          left: 'prev,next today',          center: 'title',          right: 'month,agendaweek'        },         eventclick: function(event, jsevent, view) {            $('#modaltitle').html(event.title);            $('#modalbody').html(event.name);            $('#eventurl').attr('href','/home/zapis/'+event.id);            $("#starttime").html(moment(event.start).format('hh:mm '));            if (event.end) $("#endtime").html(moment(event.end).format('hh:mm '));            else $("#endtime").html('');                          $('#fullcalmodal').modal();            return false;          },                eventlimit: true, // allow "more" link when many events        firstday: 1,                contentheight : 650,                editable : true,                allday : false,                aspectratio : 2,                slotlabelformat : 'hh:mm:ss',                timeformat : 'hh:mm',                displayeventend : true,                events: {          url: base_url + '/api',          error: function() {            alert("cannot load json");          }        },         eventcolor: 'colorrr',                    });    });  </script>

controller (pass value following view)

//.......................... //............................ $data['myval'] = "abc"; return view('myviewpage',['data'=>$data]);

blade-myviewpage(js)

<script>     //global variable on blade     var url = "{{url('/manufacturers-json')}}";     var custom_val = "{{$data['myval']}}"; //what ever getting controller ($colorr) </script>

and can use js variable js. doing way using angularjs. if in case above not work try creating input field.

<input type="hidden" value="<?php echo $colorrr; ?>" id="my_color" />

where $colorrr (or ever passing controller view, make sure variable contains value.
, in js.

var color = $("#my_color").val();
