如何在纯javascript中编写$(":not(selector)") ?

jQuery: 

var links = $('a:not(.not-lightbox-item a)', this);
HTML: 

<div id="links">
    <div class="not-lightbox-item">
        <a href="projects.html" class="button-back">
            <span class="glyphicon glyphicon-hand-left glyphicon-circle-arrow-leftx" title="Back"></span>
        </a>
        <h2 class="heading item-heading">(Title) Ways of Something</h2>
        <p>Lorem ipsum dolor sit amet <a href="#">Excepteur sint occaecat</a> cupidatat non proident</p>
    </div>
    <a href="images/banana.jpg" title="Banana">
        <img src="images/thumbnails/banana.jpg" alt="Banana">
    </a>
    <a href="images/apple.jpg" title="Apple">
        <img src="images/thumbnails/apple.jpg" alt="Apple">
    </a>
    <a href="images/orange.jpg" title="Orange">
        <img src="images/thumbnails/orange.jpg" alt="Orange">
    </a>
</div>

任何想法?

使用document.querySelector或document.querySelectorAll作为解决方案:

//returns first element matching
document.querySelector("a:not(.not-lightbox-item a)");
//returns all elements matching
document.querySelectorAll("a:not(.not-lightbox-item a)");

然而@George Katsanos是对的，使用像.lightbox-item这样的类比像a:not(.not-lightbox-item a)这样的双重否定更清晰(也可能更快)

为什么不在纯CSS中切换有选择器的类呢?

.className {
  color: blue;
}
var myitem = document.querySelector('.item')
myitem.classList.toggle('className');

如果我不能控制HTML，我就会使用:
