jQuery realizes page turning effect by pressing the keyboard direction key

1. jQuery code:

$(document).ready(function(){ 

    var prevpage=$("#pre").attr("href"); 

    var nextpage=$("#next").attr("href"); 

    $("body").keydown(function(event){ 

      if(event.keyCode==37 && prevpage!=undefined) location=prevpage; 

      if(event.keyCode==39 && nextpage!=undefined) location=nextpage; 

    }); 

 }); 

2. Html code:

<p>

 on 1 Article: 

<a id='pre' href='//www.ofstack.com/sitejs-17294-1.html'>1 With the scroll bar sliding left and right gradually into the page layout </a> 

</p> 

<p>

 Under the 1 Article: 

<a id='next' href='//www.ofstack.com/sitejs-18339-1.html'> Click the check box to add or remove value Value to the input In the input box </a> 

</p>
