Selects all elements.
Caution: The all, or universal, selector is extremely slow, except when used by itself.
jQuery( "*" )
version added: 1.0
Examples:
Find every element (including head, body, etc) in the document. Note that if your browser has an extension/add-on enabled that inserts a <script> or <link> element into the DOM, that element will be counted as well.
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>all demo</title>
<style>
h3 {
margin: 0;
}
div, span, p {
width: 80px;
height: 40px;
float: left;
padding: 10px;
margin: 10px;
background-color: #EEEEEE;
}
</style>
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
</head>
<body>
<div>DIV</div>
<span>SPAN</span>
<p>P <button>Button</button></p>
<script>
var elementCount = $( "*" ).css( "border", "3px solid red" ).length;
$( "body" ).prepend( "<h3>" + elementCount + " elements found</h3>" );
</script>
</body>
</html>
Find all elements within document.body so elements like head, script, etc. are excluded.
