how to pass parse json value through javascript

I'm trying to get the JSON object from a JSON outputted string from a Rails app. Currently in JavaScript I'm doing:

data = "<%= @chromosomes%>";

However, since there are quotes at the beginning and end of the JSON object, it is not being rendered as a JSON object. Instead it is doing something like

data = "[{"name"=>"YHet","organism_id"=>"4ea9b90e859723d3f7000037"}]"

Is there a way that I can remove the beginning and end quotes so that the object is treated as an array instead of a string?

data = '<%= @chromosomes%>'; var result = JSON.parse(data);

if you do console.log(result), it outputs a json object. This is a pure JavaScript approach and you require a reasonably modern browser that supports parsing JSON into a native object.

Use html_safe in the view, no quotes:

<script>
  data = <%= @chromosomes.html_safe %>;
</script>

Use JSON.parse to parse string into JSON object.

data = JSON.parse('<%= @chromosomes%>');
