Remove all paragraphs from the DOM.

Note: .detach() is used to remove the set of matched elements from the DOM.

Sample solution :

HTML Code :

<!DOCTYPE html>
<html>
<head>
<script src="https://code.jquery.com/jquery-git.js"></script>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>Remove all paragraphs from the DOM.</title>
</head>
<body>
<ul>
<li>Exercises</li>
</ul>
<p>jQuery</p>
<p>JavaScript</p>
<button>Attach/detach paragraphs</button>
</body>
</html>

CSS Code :

p {
background: orange;
margin: 6px 0;
}
p.off {
background: black;
}

JavaScript Code :

$( "p" ).click(function() {
$( this ).toggleClass( "off" );
});
var p;
$( "button" ).click(function() {
  if ( p ) {
p.appendTo( "body" );
p = null;
} else {
p = $( "p" ).detach();
}
});
