Unable to assign the value of a Ruby variable to a JavaScript variable

I have a Ruby variable that contains latitude and longitude coordinates:

@json = [{"lat":37.8690058,"lng":-122.2555342},{"lat":37.8739362,"lng":-122.2653001},{"lat":37.8701101,"lng":-122.2578559}]

When I attempt to use this variable in a JavaScript script:

<script type="text/javascript" charset="utf-8">

   var test = <%= @json %>
   console.log(test);

</script>

Firebug reports an error:

invalid property id
var test = [{&quot;lat&quot;:37.869005...707408,&quot;lng&quot;:-122.2545767}]

How can I successfully assign the variable in this situation?

Answer №1

It appears that your JSON quotes are being converted to HTML entities. Consider using .html_safe

var test = <%= @json.html_safe %>

If this solution does not work, you may want to refer to this other post since I am not an expert in Ruby,

Don't escape html in ruby on rails

Answer №2

Suppose we have an @json object in Ruby:

<%= javascript_tag do %>
  var test = <%= @json.to_json.html_safe %>;
<% end %>
