从多个Cookie读取值

Question

I have a js function readCookie which is currently reading value from 1 cookie named test1_cookie using regex. However I want the same function to read test2_cookie as well. What's the best way to do that?

function readCookie(name) {
            var result = document.cookie.match(new RegExp('test1_cookie=([^;]+)'));
            result && (result = JSON.parse(result[1]));
            return result ? result[name] : null;
        }

I want to read test2_cookie as well. || does not work

Answer 1

You could use the RegExp /(?:test[1-2])_cookie=([^;]+)/ which would create a non-capturing group for the test1/test2 match, and then match the subsequent cookie data.

This one would work a little better as it would match any cookie's value in the format test_cookie (ie test1_cookie, test2_cookie, test3_cookie.)

/(?:test[0-9])\\_cookie\\=([^;]+)/
