Question

Is it possible to get numbers within brackets from string with RegEx?
For example, I have selects with content like:

<select class="selectoption">
    <option value="1">no numbers</option>
    <option value="2">3 (+110.0 грн.)</option>
    <option value="3">Blabla (+95.5 грн.)</option>
</select>

I need to get only numbers, when user select option with brackets (110 or 95.5).

Now I have:

$('.selectoption').change(function() {
    if ( $("select option:selected").text().match(/\(.*\)/).length ){}
        alert (
            $("select option:selected").text().match(/\(.*\)/)
        );
    end
});

But it returns (+110.0 грн.) 🙁

Match returns array of char group which you defined in regexp.
You can use replace instead match

  $("select option:selected").text().replace(/^(.*)\([^\)\d]*(\d+\.\d+)[^\)\d]*\)$/, '$2')
