Siblings have the same parent element.

With jQuery, you can traverse an element's sibling elements in the DOM tree.


Horizontal traversal in the DOM tree

There are many useful methods that allow us to traverse the DOM tree horizontally:

  • siblings()

  • next()

  • nextAll()

  • nextUntil()

  • prev()

  • prevAll()

  • prevUntil()


jQuery siblings() method

siblings() method returns the selected All siblings of an element.

The following example returns all sibling elements of <h2>:

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <style>
        .siblings *
        {
            display: block;
            border: 2px solid lightgrey;
            color: lightgrey;
            padding: 5px;
            margin: 15px;
        }
    </style>
    <script src="http://libs.baidu.com/jquery/1.10.2/jquery.min.js">
    </script>
    <script>
        $(document).ready(function(){
            $("h2").siblings().css({"color":"red","border":"2px solid red"});
        });
    </script>
</head>
<body class="siblings">
<div>div (父元素)
    <p>p</p>
    <span>span</span>
    <h2>h2</h2>
    <h3>h3</h3>
    <p>p</p>
</div>
</body>
</html>

You can also use optional parameters to filter pairs of siblings Element search.

The following example returns all <p> elements that are siblings of <h2>:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<style>
.siblings *
{ 
display: block;
border: 2px solid lightgrey;
color: lightgrey;
padding: 5px;
margin: 15px;
}
</style>
<script src="http://libs.baidu.com/jquery/1.10.2/jquery.min.js">
</script>
<script>
$(document).ready(function(){
  $("h2").siblings("p").css({"color":"red","border":"2px solid red"});
});
</script>
</head>
<body class="siblings">
<div>div (父元素)
  <p>p</p>
  <span>span</span>
  <h2>h2</h2>
  <h3>h3</h3>
  <p>p</p>
</div>
</body>
</html>

jQuery next() method

next() method returns the next sibling element of the selected element.

This method only returns one element.

The following example returns the next sibling element of <h2>:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<style>
.siblings *
{ 
display: block;
border: 2px solid lightgrey;
color: lightgrey;
padding: 5px;
margin: 15px;
}
</style>
<script src="http://libs.baidu.com/jquery/1.10.2/jquery.min.js">
</script>
<script>
$(document).ready(function(){
$("h2").next().css({"color":"red","border":"2px solid red"});
});
</script>
</head>
<body class="siblings">
<div>div (父元素)
  <p>p</p>
  <span>span</span>
  <h2>h2</h2>
  <h3>h3</h3>
  <p>p</p>
</div>
</body>
</html>

jQuery nextAll() Method

nextAll() method returns all following sibling elements of the selected element.

The following example returns all following sibling elements of <h2>:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<style>
.siblings *
{ 
display: block;
border: 2px solid lightgrey;
color: lightgrey;
padding: 5px;
margin: 15px;
}
</style>
<script src="http://libs.baidu.com/jquery/1.10.2/jquery.min.js">
</script>
<script>
$(document).ready(function(){
$("h2").nextAll().css({"color":"red","border":"2px solid red"});
});
</script>
</head>
<body class="siblings">
<div>div (父元素)
  <p>p</p>
  <span>span</span>
  <h2>h2</h2>
  <h3>h3</h3>
  <p>p</p>
</div>
</body>
</html>

jQuery nextUntil( ) Method

#nextUntil() method returns all following sibling elements between the two given parameters.

The following example returns all sibling elements between the <h2> and <h6> elements:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<style>
.siblings *
{ 
display: block;
border: 2px solid lightgrey;
color: lightgrey;

}

</script>
</head>
<body class="siblings">
<div>div (父元素)
  <p>p</p>
  <span>span</span>

  <h3>h3</h3>
  <h4>h4</h4>
  <h5>h5</h5>
  <h6>h6</h6>
  <p>p</p>
</div>
</body>
</html>

Query prev(), prevAll() & prevUntil() methods

prev(), prevAll() and prevUntil() methods work similarly to the above methods, except It's just the opposite direction: they return the previous sibling element (traversing backward along the sibling elements in the DOM tree, not forward).
