<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script><script type="text/javascript">// <![CDATA[
jQuery(document).ready(function(){
jQuery(".stars-wrapper").makeItStar();	
});
(function($){
	$.fn.makeItStar=function(){
		this.each(function(){
		var str='';
			$(this).find("input[type=radio]").each(function(){
			$(this).hide();
				str+='<a rel="'+$(this).attr("id")+'" href="javascript:;" rel="nofollow"></a>';
			});
			str="
 
 
<div class='rating-box makeItStar'>"+str+"</div>
 
";
			$(this).append(str);
 
			$(this).find(".rating-box").children("a").hover(function(){
 
				$(this).closest(".rating-box").find("a").removeClass("active");
				var idx=$(this).index();
				for(i=0;i<=idx;i++){ 					$(this).closest(".rating-box").find("a:eq("+i+")").addClass("active"); 			 				} 			}); 			$(this).find(".rating-box").children("a").click(function(){ 				var cix=$(this).index(); 				 				$(this).closest(".rating-box").parent().find("input[type=radio]").removeAttr("checked"); 				$(this).closest(".rating-box").parent().find("input:eq("+cix+")").attr('checked', "checked"); 			}); 			$(this).find(".rating-box").mouseenter(function(){ 			}).mouseleave(function(){ 			$(this).find("a").removeClass("active"); 				var cidx=-1; 				 				$(this).parent("div").find("input").each(function(i){ 				 					if($(this).attr('checked')=="checked"){ 						cidx=i; 					} 				}); 				 				if(cidx>=0){
					for(i=0;i<=cidx;i++){ 						$(this).closest(".rating-box").find("a:eq("+i+")").addClass("active"); 					} 				} 			}) 		}); 	} })(jQuery)
// ]]></script>
