How to Select Element That Does Not have Specific Class
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>
To select the <li> that has not completed nor selected class:
document.querySelector("li:not(.completed):not(.selected)");Fiddle
You can try the :not() selector
var completeTask = document.querySelector("li:not(.completed):not(.selected)");
