From Ruby array to JS array in Rails - "quote"?

Question

I have a Ruby array like this in my controller:

@location_list = [ ['Mushrooms', 3], ['Onions', 1], ['Olives', 1], ['Zucchini', 1], ['Pepperoni', 2] ] 

And I find it like this in my opinion:

 location_list = "<%= @location_list.to_json %>"; 

But if I do an alert (location_list), I get:

 [["Mushrooms",3],["Onions",1],["Olives",1],["Zucchini",1],["Pepperoni",2]] 

How to get the corresponding object without these "quot

Answer 1

Try:

 <%= raw @location_list.as_json %> 

Using to_json will render the string with embedded double quotes and will need to be escaped using JS. And it will be a string, not an array.

Answer 2

This worked for me:

 <%= @location_list.to_s.gsub(''', '') %> 

Basically use .to_s to convert the entire array to a string, then use .gsub(''','') to remove quotes, replacing them with nothing.
