How to dynamically add table rows and cells with JavaScript using a single selection input

I am working on a project that involves a selection input with around 5 options. Additionally, there is an empty table that follows this format:

<table>
   <tr>
      <td>X (for deletion)</td>
      <td>Option name</td>
      <td>Value linked to the option name</td>
   </tr>
</table>

My goal is to dynamically add a new <tr> element with 3 <td> each time a user selects an option from the menu. The first <td> will display an "X" or image for deleting the row, the second <td> will show the option name, and the third <td> will have a value linked to that option.

I am looking for guidance on how to create a program that can automatically add the <tr> and its <td>s. Additionally, I need help implementing functionality so that when a user clicks on the "X", it deletes the entire parent <tr>. If possible, I would also like suggestions on how to sum up all values in the 3 <td>s and display the total on screen.

It's a lot to ask, but if anyone has any insights or solutions, I would greatly appreciate your help. Thank you for taking the time to read this.

Answer №1

Give this code a try to achieve what you need:

$('button').click(function() {
  $('table').append('<tr><td class="remove">X</td><td class="optionValue">' + $('select option:selected').text() + '</td><td class="linkedValue">' + $('select').val() + '</td></tr>');
})

$(document).on('click', '.remove', function() {
    $(this).parent().remove();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<select>
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="mercedes">Mercedes</option>
  <option value="audi">Audi</option>
</select>

<button type="button">Enter</button>
<br />
<br/>
<table>
  <tr>
    <td>X(for delete)</td>
    <td>Option name</td>
    <td>Value that is linked to that option name</td>
  </tr>
</table>
