How can I get to_json to escape front slashes

Question

In rails, if I call "</script>".to_json, the result is "\"</script>\"". Neither angle brackets or front slashes are escaped. Is there a way to get to_json to escape these?

This little erb snippet demonstrates the problem:

<%= javascript_tag do %>
var a = <%= raw("</script>".to_json) %>;
alert("hi");
<% end %>

This produces the following output:

<script type="text/javascript"> 
//<![CDATA[

    var a = "</script>";
    alert("hi");

//]]>
</script>  

In this case, the script tag is closed prematurely. Anyone have a good solution?

The slashes can be removed by using JSON.parse().

First of all you need to extract the body from the response that you are getting.

response_body = response_you_get_after_request.body

then pass response as argument as following:-

 filtered_response = JSON.parse(response_body).
