<SCRIPT type=text/javascript>
var t = n = 0, count = $("#focus_list a").size();
$(function(){ 
 $("#focus_list a:not(:first-child)").hide();
 $("#focus_content div:not(:first-child)").hide();
 //$("#focus_info").html($("#focus_list a:first-child").find("img").attr('alt'));
 $("#focus_text li:first-child").css({"background":"#fff",'color':'#000'});
 $("#focus_info").click(function(){window.open($("#focus_list a:first-child").attr('href'), "_blank")});
 $("#focus_text li").click(function() {
  var i = $(this).text() - 1;
  n = i;
  if (i >= count) return;
  //$("#focus_info").html($("#focus_list a").eq(i).find("img").attr('alt'));
  $("#focus_info").unbind().click(function(){window.open($("#focus_list a").eq(i).attr('href'), "_blank")})
  $("#focus_list a").filter(":visible").fadeOut(1).parent().children().eq(i).fadeIn(1);
  $("#focus_content div").filter(":visible").fadeOut(1).parent().children().eq(i).fadeIn(1);
  $(this).css({"background":"#fff",'color':'#000'}).siblings().css({"background":"#000",'color':'#fff'});
 });
 t = setInterval("showAuto()", 3000);
 $("#focus").hover(function(){clearInterval(t)}, function(){t = setInterval("showAuto()", 3000);});
})
function showAuto()
{  n = n >= (count - 1) ? 0 : ++n;
 $("#focus_text li").eq(n).trigger('click');
}
