在javascript字符串中转义引号

Question

I'm trying to escape the quotes (and apostrofes and escape char) in a text string in javascript:

var text = 'Escape " and \' and /.';
var rx = new RegExp('/([\'"])/g');
console.log(text, ' ==> ', text.replace(rx,'//\1'));​​​​​

What I expect to be output is Escape /" and /' and //. , but instead I get Escape " and ' and /. .

I just can't seem to get this working and don't know what's wrong.

Here's a JSFiddle: http://jsfiddle.net/hvtgf/

Answer 1

Escaping means using backslash \\ but not slash / .

However, for your purposes you can try the following:

text.replace(/([/'"])/g, "/$1");
