jQuery Selector vs DOM querySelectorAll
What is the Difference Between jQuery Selector and DOM querySelectorAll()?
As of , all major browsers have
querySelectorAll() method. For example:
let x = document .querySelectorAll("span.x, span.y");
[see DOM: Get Elements by ID, Tag, Name, Class, CSS Selector]
So, why use jQuery?
• Internet Explorer 8 or before does not fully support
querySelectorAll(css_selector) [see CSS Selector Syntax]
• The array-like object returned by
$(…) is more powerful than the array-like object (a NodeList) returned by
querySelectorAll(…). [see JS: Array-Like Object], because:
jQuery selector returns a special jQuery object. This object, has methods that work with html elements. All of them work on the result, by simply using the dot syntax of property access (aka chaining), and they apply to each element without needing to use map or for loop.
querySelectorAll(…) return a HTMLCollection,
which is a array-like object.
you have to use map or loop and apply functions to do
The disadvantage of using jQuery is speed and bloat.
