Paul,
thanks for the suggestion. I was hoping there is something in Rails to do
that for me. But I guess there isn't.
Other suggestion I got, off this list, is to have JSON embedded in a
javascript string, and parsed by jQuery into an object. With proper
javascript escaping (by j method), that gets the job done. And I like that
approach better then calling h on attributes on server side, as this is more
generic IMO, since it will work for any Ruby object.
Here is the code that works:
<% tags = [{name:"tag1", color:"green"}, {name:"</script><b>I can \n\ndo
something bad here</b>", color:"red"}] %>
<script type="text/javascript" charset="utf-8">
//<![CDATA[
var tags_list = $.parseJSON('<%=j tags.to_json.html_safe %>');
// ]]>
</script>
And that results in:
<script type="text/javascript" charset="utf-8">
//<![CDATA[
var tags_list =
$.parseJSON('[{\"name\":\"tag1\",\"color\":\"green\"},{\"name\":\"<\/script><b>I
can \\n\\ndo something bad here<\/b>\",\"color\":\"red\"}]');
// ]]>
</script>
Thanks all!
