Jquery幻灯片放映：正确的触发器？

我在实现Soh Tanaka优秀的jQuery技术时遇到了一些问题。我需要将触发器锚定标记嵌套在无序列表中，这会破坏脚本（将锚定标记从

列表中拉出，否则会更正问题）。我认为这取决于$selected是如何定义的，这一行：

$selected = $('#ix_slideshow_nav li a.selected').next();

HTML

---

找到正确路径的答案：

$selected = $('#ix_slideshow_nav li a.selected').parent().next().find('a'); //Move to the next nav item

给我在Bendyworks.com上的朋友一个帽子提示，让他们回答这个问题
…你不能把一个作为Matti的直接孩子，对吧--编辑HTML来修复。非常感谢。

    $(document).ready(function(){

    //Show the paging and activate its first link
    $("#ix_slideshow_nav a:first").addClass("selected");

    //Get size of the image, how many images there are, then determine the size of the image reel.
    var imageWidth = $("#ix_slideshow_window").width();
    var imageSum = $("#ix_slideshow_reel .ixss dd img").size();
    var imageReelWidth = imageWidth * imageSum;

    //Adjust the image reel to its new size
    $("#ix_slideshow_reel").css({'width' : imageReelWidth});


    //Paging  and Slider Function
    rotate = function(){
        var triggerID = $selected.attr("rel") -1; //Get number of times to slide
        var image_reelPosition = triggerID * imageWidth; //Determines the distance the image reel needs to slide

        $("#ix_slideshow_nav a").removeClass('selected'); //Remove all selected class
        $selected.addClass('selected'); //Add selected class (the $selected is declared in the rotateSwitch function)

        //Slider Animation
        $("#ix_slideshow_reel").animate({
            left: -image_reelPosition
        }, 500 );

    }; 

    //Rotation  and Timing Event
    rotateSwitch = function(){
        play = setInterval(function(){ //Set timer
            $selected = $('#ix_slideshow_nav li a.selected').next(); //Move to the next nav item
            if ( $selected.length === 0) { //If slideshow nav reaches the end...
                $selected = $('#ix_slideshow_nav a:first'); //go back to first
            }
            rotate(); //Trigger the paging and slider function
        }, 2000); //Timer speed in milliseconds 
    };

    rotateSwitch(); //Run function on launch

    //On Hover
    $("#ix_slideshow_nav a").hover(function() {
        clearInterval(play); //Stop the rotation
    }, function() {
        rotateSwitch(); //Resume rotation timer
    }); 

    //On Click
    $("#ix_slideshow_nav a").click(function() {
        $selected = $(this); //Activate the clicked paging
        //Reset Timer
        clearInterval(play); //Stop the rotation
        rotate(); //Trigger rotation immediately
        rotateSwitch(); // Resume rotation timer
        return false; //Prevent browser jump to link anchor
    });


});

$selected = $('#ix_slideshow_nav li a.selected').parent().next().find('a'); //Move to the next nav item
