Escape string in javascript

Question

I need to escape this string somehow (with newlines):

:-\\
"123"
:-/

And get this after escaping:

:-\\\\n\\"123\\"\\n:-/

I tried this, but it's not what I needed.

:-\\\n/"123/"\n:-/      .replace(/"/g,'/\"')
:-\\\n/"123/"\n:-/      .replace(/"/g,'\/"')
:-\\\n\\"123\\"\n:-/    .replace(/"/g, '\\"') ???

Don't mess with replaces, use JSON.stringify :

 text = document.querySelector('pre').textContent; text = JSON.stringify(text).slice(1, -1) alert(text) 

 <pre> :-\\ "123" :-/ </pre>
