How to Select Element That Does Not have Specific Class

Question

I\'m wondering how to select an element that does not have a specific class using JavaScript, not jQuery.

For example, I have this list:

Answer 1

You can try the :not() selector

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

Answer 2

document.querySelectorAll('[wf-body=details] input:not(.switch):not(.btn)').forEach(function(e){
    // do whatever you want. with 'e' as element :P
});

Answer 3

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

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

Answer 4

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>

Answer 5

Try getting an array of the parent's children instead:

var completeTask = document.querySelector("#tasks").childNodes;

Then loop/search them as necessary.
