Answer 1

If JavaScript code is internal then you can do this:

Otherwise:

create hidden textarea and set @hives.html_safe as its value now you can get it in JavaScript as element's value as shown below:

In html.erb file

<%= text_area_tag :hives_yearly_temp, @hives.html_safe, { style: "display: none;"} %>

In js file

var hives = JSON.parse( $('#hives_yearly_temp').val() );

To run loop

for(key in hives) {
  alert( hives[key] );
}
