なぜ$('a.current').parent('li').addClass('current');
と$(this).hasClass('current').parent('li').addClass('current');
が機能しないのですか?
a
クリックイベントにはli.current
http://jsfiddle.net/laukstein/ytnw9/を追加する必要があります

$(function(){
var list=$('#list'),
elementsPerRow=-1,
loop=true,
// find first image y-offset to find the number of images per row
topOffset=list.find('a:eq(0)').offset().top,
numTabs=list.find('li').length-1,
current,newCurrent;
function changeTab(diff){
// a.current set by jQuery Tools tab plugin
current=list.find('a.current').parent('li').addClass('current').index();
newCurrent=(loop)?(current+diff+numTabs+1)%(numTabs+1):current+diff;
if(loop){
if(newCurrent>numTabs){newCurrent=0;}
if(newCurrent<0){newCurrent=numTabs;}
}else{
if(newCurrent>numTabs){newCurrent=numTabs;}
if(newCurrent<0){newCurrent=0;}
}
// don't trigger change if tab hasn't changed (for non-looping mode)
if (current!=newCurrent){
list.find('li').eq(current).removeClass('current');
list.find('li').eq(newCurrent).addClass('current').find('a').trigger('click'); // trigger click on tab
}
}
list
// set up tabs
.tabs("#content",{effect:'ajax',history:true})
// find number of images on first row
.find('a').each(function(i){
// $(this).hasClass('current').parent('li').addClass('current');
if(elementsPerRow<0&&$(this).offset().top>topOffset){
elementsPerRow=i;
}
});
// Set up arrow keys
// Set to document for demo, probably better to use #list in the final version.
$(document).bind('keyup focus',function(e){
var key=e.keyCode;
if(key>36&&key<41){
if(key==37){changeTab(-1);} // Left
if(key==38){changeTab(-elementsPerRow);} // Up
if(key==39){changeTab(+1);} // Right
if(key==40){changeTab(+elementsPerRow);} // Down
e.preventDefault();
}
});
// toggle looping through tabs
$(':button').click(function(){
loop=!loop;
$('#loopStatus').text(loop);
});
$('a.current').parent('li').addClass('current');
