Mongodb – Retrieving variable values from Javascript file rather than HTML/CSS

I apologize if this is a simple issue but I’ve spent a long time being completely stuck, all guides are retrieving from the HTML file, and as such I have no clue where to even begin or what to search.

        <form class="container" method="post">
            <div class="form-group">
                <input class="form-control" name="title">
            </div>
            <textarea class="form-control" name="content"></textarea>
            <button>add to mongodb</button>
        </form>

From this code in the HTML file, I can retrieve the values inputted,

app.post("/", function(req, res) {
    let newGameData = new gameData ({
        score: req.body.title,
        jumps: req.body.content,
    });
    newGameData.save();
    res.redirect('/')
})

However, instead of retrieving values from HTML forms, I want to retrieve variables from a game inside the HTML, the javascript file containing the below

var score = [];
var jumps = [];

These variables are appended to as the score increases and as the character jumps, at the end of each life, I want to append it to the score, and periodically retrieve this data to be uploaded onto MongoDB, and vice versa I retrieve and display the highscore.

I was thinking to write to a json file that could be uploaded onto MongoDB, though I have no clue how to go about it or if it’s valid at all, any help would be greatly appreciated, thank you!

    As suggested in the comments, learn about Ajax. This is a sample code:

    let newGameData = {
  score: title,
  jumps: content,
};

$.post("/", newGameData, function(result) {
  console.log(result)
})

    and on the server side, don’t redirect, but rather res.send(result).

    You need to add type=submit in your button tag:

    <button type="submit">add to mongodb</button>
