Using jQuery's .append() method allows for adding <td> elements outside of <tr> tags

When using input to collect information in a form and then dynamically building it into a table, I encountered an issue with the placement of <td> elements within <tr>. In one example, the <td>'s were outside the <tr>, which I believe is due to auto-closing. However, when attempting to adjust the code to have all <td> elements within the <tr>, they appeared on separate rows.

I'm looking for guidance on how to properly structure the code to ensure that all <td> elements are contained within the same row without compromising the appearance of the table.

var $tbodyAppend = $('table > tbody:last-child');
// this puts the <td>'s outside the tr, but looks correct on the page
$tbodyAppend.append("<tr>");
$tbodyAppend.append("<td><span></span></td>");
$tbodyAppend.append("<td><span></span></td>");
$tbodyAppend.append("<td><span></span></td>");

// this puts the <td>'s in the <tr>
$tbodyAppend.append("<tr><td><span></span></td><td><span></span></td><td><span></span></td>");
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
  <tr>
    <th><span>column 1</span></th>
    <th><span>column 2</span></th>
    <th><span>column 3</span></th>
  </tr>
  <tbody>
    <!-- want jQuery to append here -->
  </tbody>
</table>

Answer №1

Outdoor activities are enjoyable because you have intentionally chosen them. Failing to close the <tr> tag does not indicate that the entire tr element was not appended.

Instead, consider appending a single string using template literals.

var $tbodyAppend = $("table > tbody:last-child").append(`
  <tr>
    <td><span> ${variableHere} </span></td>
    <td><span></span></td>
    <td><span></span></td>
  <tr><td><span></span></td><td><span></span></td><td><span></span></td>
`);

This approach not only facilitates multi-line strings but also enables string interpolation for inserting expression values into the string when necessary.

Answer №2

When adding elements to the DOM, make sure you are referencing the correct element. Consider this alternative approach:

var $tableBody = $('tbody');
$tableBody.append("<tr><td><span></span></td><td><span></span></td><td<span</span></td></tr>");
