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>
