How to Select Element That Does Not have Specific Class

To select the <li> that has not completed nor selected class:

document.querySelector("li:not(.completed):not(.selected)");

The :not(*selector*) selector also accepts commas (so does querySelectorAll()) https://developer.mozilla.org/en-US/docs/Web/CSS/:not#syntax:

let plainElements = document.querySelectorAll( ':not( .completed, .in-progress ) ');
plainElements.forEach( ( item ) => { item.style.color = 'red'; } );
li { color: green; }
<ul id="tasks">
  <li class="completed selected">Task 1</li>
  <li>Task 2</li>
  <li class="in-progress">Task 3</li>
</ul>

You can try the :not() selector

var completeTask = document.querySelector("li:not(.completed):not(.selected)");

This selects the second LI element.

document.querySelector("li:not([class])")

or

document.querySelector("li:not(.completed):not(.selected)")

Example:

// select li which doesn't have a 'class' attribute...
console.log(document.querySelector("li:not([class])"))

// select li which doesn't have a '.completed' and a '.selected' class...
console.log(document.querySelector("li:not(.completed):not(.selected)"))
 <ul id="tasks">
    <li class="completed selected">One Task</li>
    <li>Two Task</li>
  </ul>
