rails text_area format for javascript

Question

An attribute of type text needs to be generated within a javascript.

Some records have carriage returns inserted by the user and these need to be passed to javascript in form \n. However when I place

<%= uc.main_text %>

within the javascript, it returns carriage returns

Salties at bottom...

what happens here I am not certain

when \n is needed.

Salties at bottom...\n\nwhat happens here I am not certain

From the console calling the attribute returns a proper string

uc.main_text
[...] \r\n\r\n [...]

How can this be transposed for use by the javascript?

It's not clear what you're asking. Please provide more information. — fphilipe

\r\n\r\n is needed in the rendered javascript, not carriage returns. — Jerome

That doesn't help. Please share what HTML you expect for an example text. — fphilipe

javascript escape is required to make this function <%= j (uc.main_text) %> — Jerome

string = "Salties at bottom...

what \"happens\" here I 'am' not certain"
puts %{var string = "#{escape_javascript(string)}"}

This will print:

var string = "Salties at bottom...\n\nwhat \"happens\" here I \'am\' not certain"

You can try String.raw(), if I understood your question right.
