Using to_json gives me illegal character

Question

I passed a ruby variable to javascript using the to_json method, but the console returns me an error saying "SyntaxError: illegal character" for the following line:

var home = #{@home.to_json};

Does anyone knows whats wrong?

Answer 1

If this is in a .erb file you can do the following:

var home = <%= @home.to_json %>;

Otherwise (haml or something else) you could use the parseJSON method from jQuery in combination with Ruby's string interpolation:

var home = $.parseJSON("#{@home.to_json}");

More information about the parseJSON method can be found here.
