Escaping quotes in a javascript string

问题

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/

回答1:

Escaping means using backslash \ but not slash /.

However, for your purposes you can try the following:

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