jQuery – Adjacent sibling selector example

jQuery adjacent sibling selector (X + Y) is used to select the immediately follow or next elements matched by “Y” that is a sibling of a “X” element.

For example,

<div class="class1"></div>
<p>I'm class1 sibling #1</p>
<p>I'm class1 sibling #2</p>
<p>I'm class1 sibling #3</p>

The <div> and <p> are sibling relationship. The “$(.class1 + p)” statement will select the <p> element with value “I’m class1 sibling #1” only, the rest of the <p> element will be ignore.

jQuery Example

In this example, only the <div> tag with value “I’m form siblings #1 – DIV” will be match, because it’s the immediately follow or next sibling of <form> element.
