try 

'http://xxxxxxx.xxx/abcd123456789?abc=1'.match(/\d+(?=\?)/)[0];
 //                                             ^1 or more digits followed by '?'

Try

var regexp = /\/abcd(\d+)\?/;
var match = regexp.exec(input);
var number = +match[1];

Yes, regex is the right answer. You'll have something like this:

var s = 'http://xxxxxxx.xxx/abcd123456789?abc=1';
var re = new RegExp('http\:\/\/[^\/]+\/[^\d]*(\d+)\?');
re.exec(s);
var digits = $1;

Are the numbers always between "abcd" and "?"?

If so, then you can use substring(): 

s.substring(s.indexOf('abcd'), s.indexOf('?'))

If not, then you can just loop through character by character and check if it's numeric: 

var num = '';

for (var i = 0; i < s.length; i++) {
  var char = s.charAt(i);
  if (!isNaN(char)) {
    num += char;
  }
}
