jQuery Traversing Descendants
To traverse and find descendants of an element, jQuery has the following methods: children() and find().
children() method
The childreb() method in jQuery is used to return the direct children of the selected element (only a single level of direct children). Let us see an example−
Example
<!DOCTYPE html>
<html>
<head>
<style>
div {
width:600px;
}
.demo * {
display: block;
border: 2px solid orange;
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(){
$("div").children().css({"color": "gray", "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−
find() method
