How to update database on change of checkbox? (Javascript)

How can I update the database when the user clicks on the Checkbox?
So when the checkbox is checked and the user clicks on it, then the database will update a value and the checkbox remains unchecked until its checked again.

<table>
  <tr>
    <td>
      <input type='checkbox' name='all' checked>
    </td>
    <td>
      <input type='checkbox' name='all'>
    </td>
  </tr>
</table>

I like to have this written in javascript.
I don't have any code because I don't have knowledge on how to build this. Please help me with this.
