what i actually need is 75

any help will be appreciated!

the above code results in 123675, but I need it to return just 75, please help

Solution

  • Use ^.+ to match everything from the start of the input string.

    var s = "1236(75)";
var s = s.replace(/^.*\(|\)/g, '');

    That said, you could use a regex to do the opposite: instead of getting rid of everything you don't want, just match the parts you do want:

    var match = s.match(/\((\d+)|\)/)[1];
