jQuery Traversing Ancestors
To traverse and find ancestors of an element, jQuery has the following methods: parent(), parents() and parentsUntil()−
parent() method
The parent() method in jQuery is used to return the direct parent element of the selected element. Let us see an example −
Example
<!DOCTYPE html>
<html>
<head>
<style>
div {
width:600px;
}
.demo * {
display: block;
border: 2px solid yellow;
color: blue;
padding: 10px;
margin: 10px;
}
</style>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("span").parent().css({"color": "blue", "border": "3px dashed blue"});
});
</script>
</head>
<body class="demo">great-great-grandparent
<div>great-grandparent
<ul>grandparent
<li>parent
<span>span</span>
</li>
</ul>
</div>
</body>
</html>Output
This will produce the following output −
parents() method
The parents() method in jQuery is used to return all ancestor elements (till document root) of the selected element. Let us see an example −
Example
<!DOCTYPE html>
<html>
<head>
<style>
div {
width:600px;
}
.demo * {
display: block;
border: 2px solid yellow;
color: blue;
padding: 10px;
margin: 10px;
}
</style>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("span").parents().css({"color": "blue", "border": "3px dashed blue"});
});
</script>
</head>
<body class="demo">great-great-grandparent
<div>great-grandparent
<ul>grandparent
<li>parent
<span>span</span>
</li>
</ul>
</div>
</body>
</html>Output
This will produce the following output −
parentsUntil() method
The parentsUntil() method in jQuery is used to return all ancestor elements between the selector and stop parameter value.
Example
Let us now see an example to implement the jQuery parentsUntil() method −
<!DOCTYPE html>
<html>
<head>
<style>
div {
width:600px;
}
.demo * {
display: block;
border: 2px solid yellow;
color: blue;
padding: 10px;
margin: 10px;
}
</style>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("span").parentsUntil("div").css({"color": "blue", "border": "3px dashed blue"});
});
</script>
</head>
<body class="demo">great-great-grandparent
<div>great-grandparent
<ul>grandparent
<li>parent
<span>span</span>
</li>
</ul>
</div>
</body>
</html>Output
This will produce the following output −
