<ul id="menu_bar">     <li><a href="#home" class="hov selected"><img src="img/home_on.png" alt="home" />home</a></li>     <li><a href="#portfolio" class="hov"><img src="img/portfolio_off.png" alt="portfolio" />portfolio</a></li>     <li><a href="#about" class="hov"><img src="img/about_off.png" alt="about" />about</a></li>    <li><a href="#contact" class="hov"><img src="img/contact_off.png" alt="contact" />contact</a></li> </ul>

js

$(document).ready(function() {     $("img.roll").hover(         function() { this.src = this.src.replace("_off", "_over");},         function() { this.src = this.src.replace("_over", "_off");}     );     $("a.hov").hover(         function() {             var img = $(this).find("img")[0];             img.src = img.src.replace("_off", "_over");},         function() {             var img = $(this).find("img")[0];             img.src = img.src.replace("_over", "_off");}     );     $("a.hov").click(         function() {             var img = $(this).find("img")[0];             img.src = img.src.replace("_over", "_on");             $("a.hov").removeclass("selected");             $(this).addclass("selected");         }     );  });
