Review My Code


#1

So I was learning javascript and at one point I thought, maybe I could create a small game, so I went on to create "The Number Guessing Game". It is like binary search, if you dont know what that is, then search it up. I need you, to debug my code because I can't seem to fix it myself, also I know this is the wrong section, though I couldn't find a section for this, so it is here. Sorry...

My code won't really start, as it is supposed to, obviously.

JAVASCRIPT

document.addEventListener('DOMContentLoaded',function() {
    var tNum=getNum(); // The chosen number to find
    var tries=0;
        var z=document.querySelector('.button'); // The button that submits the text
        z.addEventListener('click', function () {
            numReact(tries,tNum);
            tries=numReact(tries,tNum);
            var gameOver=checkLose(tries);
            if(gameOver===true) {
                document.querySelector('.input').disabled=true; //disable the text box and submit button if games over, reset page to try again
        }
        });
});

// the chosen number
function getNum () {
    return Math.random()*100+1;
}
// the chosen number

// how to react to the number chosen by the player to the real number
function numReact (tries,tNum) { // takes in tNum and tries to try find if the player got the number and how to react
    var x= document.querySelector('.chosenNum');
    document.querySelector('.oldNum').innerHTML='YOU CHOSE' + x + '.';
    document.querySelector('.chosenNum').innerHTML= '';
    if (x<tNum) {
        document.querySelector('.tooHighLow').innerHTML= 'Too Low'; // replay with too low if the number is... too low
        tries+=1;
        return tries; // return the turn the player is on
    }else if(x>tNum) {
        document.querySelector('.tooHighLow').innerHTML= 'Too High'; // replay with too high if the number is... too high
        tries+=1;
        return tries;
    }else{
        document.querySelector('.tooHighLow').innerHTML= 'You Got It, The Number, Good Job'; 
        // replay with good job if your guessed number is the same as the real number
        document.getElementByTagName('input').disabled=true; // disable all input tags, to stop furthur confrontation
    }
}
function checkLose(tries) {
    if(tries<=10) { // if tries are less than 10, return false
        return false;
    }else{
        document.querySelector('.tooHighLow').innerHTML='Thats it, you lost the game because you have 11 tries'; // if tries are greater than 10, return true
        return true;
    }
}

                <li>If your number is too high, try a lower one, vice versa if your number is too high</li>
                <li>You have 10 tries to do such, after that, reload the page</li>
            </ul>
            <input type="text" class="chosenNum">

            <input type="button" class="input" value="CLICK ONCE">

    </html>

Please help me debug this, I really can't find the issue.
