Why is it that every time I try to execute this function, my table fails to populate as expected?

I'm having trouble creating a table with 2 rows, each row containing 4 cells that should display an image. However, when I try to execute my function, nothing seems to happen. Can you help me troubleshoot?

function generateTable()
{

    var table = document.createElement("TABLE");
    table.setAttribute("id", "gameBoard");

    var row1 = document.createElement("TR");
    row1.setAttribute("id", "r1");

    table.appendChild(row1);

    for (var i = 0; i < 4; i++)
    {
        var cell = document.createElement("TD");
        var cell_img = document.createElement('img');
        cell_img.setAttribute("src", "images/card_back.png");
        cell.appendChild(cell_img);

        row1.appendChild(cell);
    }

    var row2 = document.createElement("TR");
    row2.setAttribute("id", "r2");

    table.appendChild(row2);


    for (var j = 0; j < 4; j++)
    {
        var cell = document.createElement("TD");
        var cell_img = document.createElement('img');
        cell_img.setAttribute("src", "images/card_back.png");
        cell.appendChild(cell_img);

        row2.appendChild(cell);
    }
}

}

Answer №1

It is crucial to remember to include document.appendChild(table); at the conclusion of your code. This step ensures that the element gets added to the page, as simply using document.createElement does not automatically integrate it into the DOM.

If you wish to specify where the element should be placed, consider modifying your function to accept the id of the div container for your gameboard as a parameter.

generateTable(elementId) { ... }

Lastly, follow up with:

let toAdd = document.getElementById(elementId);
toAdd.appendChild(table);
