How do I escape a string inside JavaScript code inside an onClick handler?

Question

Maybe I\'m just thinking about this too hard, but I\'m having a problem figuring out what escaping to use on a string in some JavaScript code inside a link\'s onClick handle

Answer 1

Is the answers here that you can't escape quotes using JavaScript and that you need to start with escaped strings.

Therefore. There's no way of JavaScript being able to handle the string 'Marge said "I'd look that was" to Peter' and you need your data be cleaned before offering it to the script?
