I’ve got some code that “quotes” the contents of a blog post and  
inserts it into a comment box wrapped in a blockquote. You can view it  
here:

Problem is, every time I try to quote a block of text with more than  
one line in it, the javascript freaks out. Can anyone tell me how I  
should be parsing these line breaks properly? thanks!

Hi,

I just call the escape function (js) and it works fine e.g.

```
            <%= link_to_remote "Try it!",:url => { :action

```

=\> :test\_rule },  
:with =\> “‘code=’+escape(rule\_rule\_body.value)  
+’&input\_data=’+escape(input\_data.value)  
+’&business\_type=’+escape(rule\_business\_type.value)” %\>

which passes a block of text for evaluation to the server.
