What's the simplest way to assign unique sliders to each clicked element in this case?

javascript

I currently have a table with a javascript function where when a table cell is clicked, the entire row will be removed and the clicked cell will be copied to the leftmost position with a slider opening up on the right. However, I only have a universal slider for all clicked elements but I want to make each table cell’s slider unique. What’s the best approach for that in this case?

document.addEventListener("DOMContentLoaded", function () {
  var table = document.getElementById("TrendGames");
  table.addEventListener("click", function (event) {
    var clickedCell = event.target.closest("td");
    if (clickedCell) {
      handleCellClick(clickedCell);
    }
  });
});

function handleCellClick(clickedCell) {
  const row = clickedCell.parentElement;
  const cells = row.children;
  const display = cells[cells.length - 1].style.display ? "" : "none";

  // Hide/Show all cells
  for (var i = 0; i < cells.length; i++) {
    cells[i].style.display = display;
  }
  if (display) {
    // First click (third, fifth, ...)
    // Copy(!) the clicked cell in the leftmost position
    const newCell = clickedCell.cloneNode(true);
    newCell.style.display = "";
    newCell.colSpan = cells.length;
    row.insertBefore(newCell, row.firstChild);
    // Open the slider and display information
    openSlider(newCell);
  } else {
    // Remove the cell that was inserted on previous click
    clickedCell.remove();
    closeSlider(clickedCell);
  }
}


<table id="TrendGames">
  <tbody>
    <tr>
      <td id="cell1">
        Cell 1
        <img class="GameCover" src=".png" alt="cell1" />
      </td>
      <td id="cell2">
        Cell 2
        <img class="GameCover" src=".png" alt="cell2" />
      </td>
      <td id="cell31">
        Cell 3
        <img class="GameCover" src=".png" alt="cell3" />
      </td>
      <td id="cell4">
        Cell 4
        <img class="GameCover" src=".png" alt="cell4" />
      </td>
    </tr>
  </tbody>
</table>

If you want to make each table cell’s slider unique, you can generate a unique identifier for each slider and use it to distinguish between them. Here’s an example of how you can modify your code to achieve this:

document.addEventListener("DOMContentLoaded", function () {
  var table = document.getElementById("TrendGames");
  table.addEventListener("click", function (event) {
    var clickedCell = event.target.closest("td");
    if (clickedCell) {
      handleCellClick(clickedCell);
    }
  });
});

function handleCellClick(clickedCell) {
  const row = clickedCell.parentElement;
  const cells = row.children;
  const display = cells[cells.length - 1].style.display ? "" : "none";

  // Hide/Show all cells
  for (var i = 0; i < cells.length; i++) {
    cells[i].style.display = display;
  }
  if (display) {
    // First click (third, fifth, ...)
    // Copy(!) the clicked cell in the leftmost position
    const newCell = clickedCell.cloneNode(true);
    newCell.style.display = "";
    newCell.colSpan = cells.length;

    // Generate a unique identifier for the slider
    const sliderId = `slider_${Date.now()}_${Math.random()}`;
    newCell.setAttribute("data-slider-id", sliderId);

    row.insertBefore(newCell, row.firstChild);

    // Open the slider and display information
    openSlider(newCell);
  } else {
    // Remove the cell that was inserted on the previous click
    clickedCell.remove();
    closeSlider(clickedCell);
  }
}

function openSlider(cell) {
  // Access the unique identifier for the slider
  const sliderId = cell.getAttribute("data-slider-id");
  console.log(`Opening slider with id: ${sliderId}`);
  // Your code to open the slider
}

function closeSlider(cell) {
  // Access the unique identifier for the slider
  const sliderId = cell.getAttribute("data-slider-id");
  console.log(`Closing slider with id: ${sliderId}`);
  // Your code to close the slider
}

This modification adds a data-slider-id attribute to each cloned cell, which contains a unique identifier. The openSlider and closeSlider functions then use this identifier to operate on the correct slider.
