and something that should be avoided in general. Now, the former does have forEach defined - but it's pretty much the only array method that has been added to its prototype so far.īut it's only a relatively recent addition, so older browsers don't support it - fortunately, the Array#forEach trick works pretty well, down to sufficiently old Internet Explorer versions (probably 6? 5.5? The heck am I saying, that could work for slice, but forEach was added only in IE9.).Ī HTMLCollection is a totally different beast. To select the above elements use querySelectorAll and use a valid CSS selector to select all of the above elements.A small correction: you used document.getElementsB圜lassName which does not return a NodeList but a HTMLCollection. This nodeList contains all the elements that match the specified selector. The querySelectorAll method selects all the matching element from the document and returns a static nodeList which is an an array-like object. You can use querySelectorAll to select elements based on their tag name, attributes, class, id, combinations of these and any possible valid CSS selector. QuerySelectorAll is a DOM API used to select element in the webpage using CSS selectors. If you are already familiar with these methods, and jump to section 3. We have briefly explained both queryeSelectorall and forEach method briefly here. In this article, you will look at how to loop through the nodeList using Javascript queryeSelectorall forEach method.īefore using the forEach method with the modern API querySelectorAll you must first have a prior understanding of both of these methods.
