在 javascript 文字字符串中使用的转义字符

Question

I would like to take a string that the user will enter to a text box in a form and turn it into a javascript literal. So I'd, for instance, turn the " character into \".

Is there any complete list of characters that would need to be escaped?

Answer 1

You only need to escape your delimiter and/or whatever enclosing quotes you choose (escape double quotes if you enclose your string in double, escape single otherwise).

If you're going to render it as HTML, you may wnat to convert them to entities (eg & -> & )
