parent selector
Description: Select all elements that have at least one child node (either an element or text).
version added: 1.0jQuery( ":parent" )
This is the inverse of :empty.
One important thing to note regarding the use of :parent (and :empty) is that child nodes include text nodes.
The W3C recommends that the <p> element have at least one child node, even if that child is merely text (see https://www.w3.org/TR/html401/struct/text.html#edef-P). Some other elements, on the other hand, are empty (i.e. have no children) by definition: <input>, <img>, <br>, and <hr>, for example.
To obtain the parents or ancestors of an existing jQuery set, see the .parent() and .parents() methods.
Additional Notes:
- Because
:parentis a jQuery extension and not part of the CSS specification, queries using:parentcannot take advantage of the performance boost provided by the native DOMquerySelectorAll()method. To achieve the best performance when using:parentto select elements, first select the elements using a pure CSS selector, then use.filter(":parent").
Example:
Finds all tds with children, including text.
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>parent demo</title>
<style>
td {
width: 40px;
background: green;
}
</style>
<script src="https://code.jquery.com/jquery-3.5.0.js"></script>
</head>
<body>
<table border="1">
<tr><td>Value 1</td><td></td></tr>
<tr><td>Value 2</td><td></td></tr>
</table>
<script>
$( "td:parent" ).fadeTo( 1500, 0.3 );
