Example

Following is a simple example a simple showing the usage of this method −

<html>
   <head>
      <title>The jQuery Example</title>
      <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
		
      <script>
         $(document).ready(function(){
            $("div").find("p").andSelf().addClass("border");
         });
      </script>
		
      <style>
         p, div { margin:5px; padding:5px; }
         .border { border: 2px solid red; }
         .background { background:yellow; }
      </style>
		
   </head>
	
   <body>
	
      <div>
         <p>First Paragraph</p>
         <p>Second Paragraph</p>
      </div>
		
   </body>
</html>

Here border would be added to previous selection which is a division and then second selection which is paragraphs, as shown below −

If you would remove andSelf() method then border would be applied to paragraphs only.

<html>
   <head>
      <title>The jQuery Example</title>
      <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
		
      <script>
         $(document).ready(function(){
            $("div").find("p").andSelf().addClass("border");
         });
      </script>
		
      <style>
         p, div { margin:5px; padding:5px; }
         .border { border: 2px solid red; }
         .background { background:yellow; }
      </style>
		
   </head>
	
   <body>
	
      <div class="border">
         <p class="border">First Paragraph</p>
         <p class="border">Second Paragraph</p>
      </div>
		
   </body>
</html>
