Converting string to hash in rails

Question

I need to convert an string to hash so that i can use its "id" attribute. I am getting this string due to following code in my .js.erb file:

$('#link_id').data('test', "<%= @record_obj.as_json %>");

I am getting string in following format:

"{&quot;id&quot;=&gt;166,&quot;first_name&quot;=&gt;James}"

I need to convert above string to hash so that i can access "id" of the object.

Any help will be appreciated. Thanks :)

Add 'raw' to get a clean output when using erb inside of javascript.

$('#link_id').data('test', JSON.parse(<%= raw @record_obj.as_json %>));

Thanks for the help. Now i do not need to replace the ". I am getting it as "{"id"=>189, "first_name"=>"James"}, but as a string instead of hash. Could you please help me out over here?

I have updated the answer. The reason you are getting a string is because you had wrapped your @record_object in quotes $('#link_id').data('test', "<%= @record_obj.as_json %>"); I removed them and now you should get your raw JSON. Please upvote and mark correct if deemed correct!

If i am not wrapping it in quotes its blocking my js.erb logic.

$('#link_id').data('test', JSON.parse(<%= raw @record_obj.as_json %>)); This will convert the JSON to a Javascript object, which should enable you to iterate through it.

Thanks a lot friend. It is working. :) But i need to change as_json to to_json. Does that really matters?

Try use id directly

$('#link_id').data('test', "<%= @record_obj.id %>")

try

$('#link_id').data('test', <%= @record_obj.as_json.html_safe %>);
