JS: Get Value from string

Question

Im Looking for a way to search for a string inside a text and get the value behind it. Sorry, I am very bad at JS.

The text I'm using:

<label for="sample-group-15822160-0"><br>
<input name="sample-group-15822160" id="sample-group-15822160-0" value="option-1" numbercount="1" type="radio" checked="checked">Option 1</label>

What I need: 1

-> So just the value from the numbercount field inbetween the ".

What I tried:

var numhelper = sampleButtonObjects[index].outerHTML;
    var numhelperNum = ico1helper.split('numbercount="')[0].split('"')[1].trim();
                    var num = numhelperNum ;

What I received: sample-group-15822160-0 (the ID).

Can somebody please tell me, what I'm doing wrong? Thank you!

Can you not target the input's numbercount attribute directly? Seems like an XY Problem. — Tyler Roper

You did all good except this tiny error

ico1helper.split('numbercount="')[0].split('"')[1].trim()
                                  ^             ^

The indices must be 1 & 0 in order to work

Thank you so much Pavitra. And the way you told me (you did all good"), made me feel good. So you're my hero for today :) But, could you please explain me the difference, so that I would better understand in the future (I try to learn, not just to copy & paste) Thank you :)
