The :not() pseudo-class requires a comma-separated list of one or more selectors as its argument. The list must not contain another negation selector or a pseudo-element.
Use the classList. contains() method to check if an element does not have a specific class, e.g. if (! el. classList.
The class selector selects HTML elements with a specific class attribute.
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)");

You can try the :not()
selector
var completeTask = document.querySelector("li:not(.completed):not(.selected)");
http://jsfiddle.net/UM3j5/
document.querySelectorAll('[wf-body=details] input:not(.switch):not(.btn)').forEach(function(e){
// do whatever you want. with 'e' as element :P
});
Try getting an array of the parent's children instead:
var completeTask = document.querySelector("#tasks").childNodes;
Then loop/search them as necessary.
The :not(*selector*)
selector also accepts commas (so does querySelectorAll()
):
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>
