슬라이딩 및 불투명도 효과를 사용하여 간단한 jQuery 이미지 슬라이더를 구축하는 방법은 무엇입니까?

<ul class="images">
    <li>
        <img src="images/1.jpg" alt="1" />
    </li>
    <li>
        <img src="images/2.jpg" alt="2" />
    </li>
    ...
</ul>

<ul class="triggers">
    <li>1</li>
    <li>2</li>
    ...
</ul>
<span class="control prev">Prev</span>
<span class="control next">Next</span>

ul.images { position:relative; }
ul.images li { position:absolute; }

triggers.first().addClass('active');
images.hide().first().show();

function sliderResponse(target) {
    images.fadeOut(300).eq(target).fadeIn(300);
    triggers.removeClass('active').eq(target).addClass('active');
}

.mask { float:left; margin:40px; width:270px; height:266px; overflow:hidden;  }
ul.images { position:relative; top:0px;left:0px; }

var triggers = $('ul.triggers li');
var images = $('ul.images li');
var lastElem = triggers.length-1;
var mask = $('.mask ul.images');

triggers.first().addClass('active');

    triggers.removeClass('active').eq(target).addClass('active');

    clearInterval(timingRun);
    timingRun = setInterval(function() { sliderTiming(); },5000);
}
