Question:
I'm trying to modify a configuration of a sister div, but I'm having trouble finding the correct selector to use, I know the html works like a tree and, usually when I need to select a superior element I use parent() and when it's a bottom I use find() .
How would it be to select one of the same level?
Answer:
You can use siblings as the name says "brothers".
Example:
$('#foo').click(function() {
var t = $(this).siblings(); // Vai pegar todos os irmãos.
var t2 = $(this).siblings('#bar'); // Vai pegar apenas o irmão com id correspondente.
var t3 = $(this).siblings('.bar'); // Vai pegar todos irmãos com as classes correspondente.
console.log(t);
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div id="foo">FOO</div>
<div id="bar" class="bar">BAR</div>
<div id="bar2" class="bar">BAR2</div>if you just wanted to get the next sibling, you can also use next() .
