我需要将幻灯片效果替换 为 上一张和下一张幻灯片功能的淡出/淡入效果：

function animate(dir,clicked){
    u = true;
    switch(dir){
        case 'next':
            t = t+1;
            m = (-(t*w-w));
            current(t);
            if(o.autoHeight){autoHeight(t);}
            if(s<3){
                    if (t===3){$(o.slides,obj).children(':eq(0)').css({left:(s*w)});}
                    if (t===2){$(o.slides,obj).children(':eq('+(s-1)+')').css({position:'absolute',left:(w)});}
            }
            $(o.slides,obj).animate({left: m}, o.slidespeed,function(){
                    if (t===s+1) {
                            t = 1;
                            $(o.slides,obj).css({left:0},function(){$(o.slides,obj).animate({left:m})});
                            $(o.slides,obj).children(':eq(0)').css({left: 0});
                            $(o.slides,obj).children(':eq('+(s-1)+')').css({ position:'absolute',left:-w});
                    }
                    if (t===s) $(o.slides,obj).children(':eq(0)').css({left:(s*w)});
                    if (t===s-1) $(o.slides,obj).children(':eq('+(s-1)+')').css({left:s*w-w});
                    u = false;
            });
            break;
        case 'prev':
            t = t-1;
            m = (-(t*w-w));
            current(t);
            if(o.autoHeight){autoHeight(t);}
            if (s<3){
                    if(t===0){$(o.slides,obj).children(':eq('+(s-1)+')').css({position:'absolute',left:(-w)});}
                    if(t===1){$(o.slides,obj).children(':eq(0)').css({position:'absolute',left:0});}
            }
            $(o.slides,obj).animate({left: m}, o.slidespeed,function(){
                    if (t===0) {
                            t = s;
                            $(o.slides,obj).children(':eq('+(s-1)+')').css({position:'absolute',left:(s*w-w)});
                            $(o.slides,obj).css({left: -(s*w-w)});
                            $(o.slides,obj).children(':eq(0)').css({left:(s*w)});
                    }
                    if (t===2 ) $(o.slides,obj).children(':eq(0)').css({position:'absolute',left:0});
                    if (t===1) $(o.slides,obj).children(':eq('+ (s-1) +')').css({position:'absolute',left:-w});
                    u = false;
            });
            break;
        case 'fade':
            t = [t]*1;
            m = (-(t*w-w));
            current(t);
            if(o.autoHeight){autoHeight(t);}
            $(o.slides,obj).children().fadeOut(o.fadespeed, function(){
                    $(o.slides,obj).css({left: m});
                    $(o.slides,obj).children(':eq('+(s-1)+')').css({left:s*w-w});
                    $(o.slides,obj).children(':eq(0)').css({left:0});

 };

我试过了，但自动重启不起作用！

这很容易编辑。

            current(t);
            if (t === s) { t = 0; }

我没有对此进行测试，但我所做的只是将 .animate 函数替换为 .fadeOut 函数。 

function animate(dir,clicked){  
                u = true;       
                switch(dir){
                        case 'next':
                                t = t+1;
                                m = (-(t*w-w));
                                current(t);
                                if(o.autoHeight){autoHeight(t);}
                                if(s<3){
                                        if (t===3){$(o.slides,obj).children(':eq(0)').css({left:(s*w)});}
                                        if (t===2){$(o.slides,obj).children(':eq('+(s-1)+')').css({position:'absolute',left:(w)});}
                                }
                                $(o.slides,obj).fadeOut(o.fadespeed ,function(){
                                        if (t===s+1) {

1）我引入了一个变量来跟踪我们展示东西的容器的左侧：

//these are default options just declare our variable below these
var n = 0;
var interval=0;
var restart=0;
var cLeft = $(o.container).position().left+'px';//Left of Container

2）下一个修改prev和next侧面switch声明中的功能：

function animate(dir,clicked){
    u = true;
    switch(dir){
    case 'next':
        t = t+1;
        m = (-(t*w-w));
        current(t);
        if(o.autoHeight){autoHeight(t);}

        var pre=0;
        if(t===s+1){t = 1; }
        if(t===1){ pre=s; }
        else{ pre = t-1; }
        $(o.slides,obj).children(':eq(' + (pre-1) + ')')
             .css({position:'absolute',left:cLeft,'z-index':'1'})
             .fadeOut('slow');
        $(o.slides,obj).children(':eq(' + (t-1) + ')')
             .css({position:'absolute',left:cLeft,'z-index':'500'})
             .fadeIn('slow');
        u = false;
        break;
    case 'prev':
        t = t-1;
        m = (-(t*w-w));
        current(t);
        if(o.autoHeight){autoHeight(t);}

        var pre=1;
        if(t===0){ t = s; }
        else{ pre = t+1; }
        $(o.slides,obj).children(':eq(' + (pre-1) + ')')
                .css({position:'absolute',left:cLeft,'z-index':'1'})
                .fadeOut('slow'); //FADEOUT CURRENT IMAGE
        $(o.slides,obj).children(':eq(' + (t-1) + ')')
                .css({position:'absolute',left:cLeft,'z-index':'500'})
                .fadeIn('slow');//FADEIN NEXT ONE
        u = false;
        break;
        //....
        //....rest of the stuff which you can modify like this

这是我的代码版本。这会将默认幻灯片效果更改为淡入/淡出效果。我正在使用 loopedSlider 0.5.5 - jQuery 插件。自动启动功能也运行良好。您会注意到下面有重复的代码行。您可以自己轻松解决此问题。

    function animate(dir,clicked){
        active = true;
        switch(dir){
            case "next":
                if(times>slides-1){ times = 0; }
                times = times+1;
                distance = (-(times*width-width));
                current(times);

我使用了以下代码，这似乎对我有用：

      case "next":
          times = times+1;
          distance = (-(times*width-width));
          current(times);
          if(o.autoHeight){autoHeight(times);}
          $(o.slides,$t).children().fadeOut(o.fadespeed, function(){
              $(o.slides,$t).css({left: distance});
              $(o.slides,$t).children(":eq("+(slides-1)+")").css({left:slides*width-width});
              $(o.slides,$t).children(":eq(0)").css({left:0});
              if(times===slides+1){
               times = 1;
              distance = (-(times*width-width));
              current(times);
               }
              if(times===slides)
              {$(o.slides,$t).children(":eq(0)").css({left:(slides*width)});}
              if(times===slides-1)
              {$(o.slides,$t).children(":eq("+(slides-1)+")").css({ position:"absolute",left:-width});}
              $(o.slides,$t).children().fadeIn(o.fadespeed);
              active = false;;
              });
              break;

我希望这可以帮助别人 ：）
