打破
案例“prev”:

t=(t这个特定的插件不是为淡入淡出而构建的。

找到它

if(!options.vertical) {
                    p = (t*w*-1);
                    $("ul",obj).animate(
                        { marginLeft: p }, 
                        { queue:false, duration:speed, complete:adjust }
                    );              
                } 
并将其更改为

if(!options.vertical) {
                    p = (t*w*-1);
                    $("ul",obj).animate(
                        { opacity: 0 }, 
                        { queue:false, duration:'slow', complete:adjust }
                    );  

                }
if(!options.vertical) {
                $("ul",obj).css("margin-left",(t*w*-1));
                $("ul",obj).animate(
                        { opacity: 1 }, 
                        { queue:false, duration:'slow'}
                    );  
            }
然后找到这个

if(!options.vertical) {
                $("ul",obj).css("margin-left",(t*w*-1));
            }
并将其更改为

if(!options.vertical) {
                    p = (t*w*-1);
                    $("ul",obj).animate(
                        { opacity: 0 }, 
                        { queue:false, duration:'slow', complete:adjust }
                    );  

                }
if(!options.vertical) {
                $("ul",obj).css("margin-left",(t*w*-1));
                $("ul",obj).animate(
                        { opacity: 1 }, 
                        { queue:false, duration:'slow'}
                    );  
            }
