I need to render this string that is stored in db:

<span style=\"color: #333333; font-family: 'Open Sans', Helvetica, Arial, sans-serif; font-size: 24px; line-height: 40px;\">Potentiometer</span>

When I try to assign it to a var like this:

var description:"<%= s.html_safe %>";

I get this error near 'Open Sans' :

Uncaught SyntaxError: Unexpected identifier

Although I used ' not " at var description:"<%= s.html_safe %>"; the resulted javascript will look like:

var description= '<span style=\"color: #333333; font-family: 'Open Sans', Helvetica, Arial, sans-serif; font-size: 24px; line-height: 40px;\">Potentiometer</span>';

This will cause an error as string starts with ' and it has ' too

Can someone help?

EDIT

The solution found is to use gsub and replace each ' with "

<%- s= raw(s.gsub(/'/, "\"")) %>

$scope.circuits.unshift({circuit:"<%= @experiment.circuit %>", description:'<%=s%>'});

What language are you using? Ruby does not use `var` to declare variables. – Wand Maker Jan 23 '16 at 13:29
why not escape the quotes, i.e. \'Open Sans\' (since it's from db, with js replace for example) – devlock Jan 23 '16 at 13:29
its javascript with ruby, I 've found the solution anyway, thanks guys, see the edit – simo Jan 23 '16 at 13:34

Please don't use `raw` with `gsub`. Follow the link @ArieShaw posted and use `escape_javascript`. – Philip Hallstrom Jan 23 '16 at 18:36
