Ruby json gem is encoding html entities

问题

I make a hash called timeOffsets in my code

@timeOffsets = Hash.new
total=0
@sections.each do |i|
  @timeOffsets[i.shortcode] = total
  total+=i.length
end

And I render it in Javascript using to_json, :

timeOffsets=<%=@timeOffsets.to_json%>;

but I get it with the HTML entities encoded:

timeOffsets={"Introduction_to_Lists":0,"Removing_elements":693,"Joining__join_":1490};

How do I stop it from encoding the HTML entities?

回答1:

timeOffsets=<%=raw @timeOffsets.to_json%>

Use the raw view helper.
