Question:
In jQuery, we use quotes to get $('div.oi') . What about pure JavaScript? Piss if we use no quotes is different.
If we are going to change the css for example: With jQuery:
$('teste').css(teste);
Answer:
The modern way in pure JS is:
// Para um elemento, por seletor
var el = document.querySelector('div.oi');
// Para múltiplos elementos
var els = document.querySelectorAll('div.oi');
// Para um elemento por ID, da maneira tradicional:
var el = document.getElementById('id_aqui');
Both querySelector and querySelectorAll can be applied either to the document or to a specific element (to get descendants of it).
There are also other methods, such as getElementsByClassName , that need to be used in older browsers.
