轮播从无到有

1.轮播形式

千奇百怪，常见：透明度、位移

2.代码实现

2.1.1 初级实现自动轮播功能

var wrap = $('.my-slide');

    // content
    var content_wrap = wrap.find('.slide-wrapper');
    var content_lis = content_wrap.find('li');

    // bottom box
    var btn_wrap = wrap.find('.slide-box');
    var btn_lis = btn_wrap.find('li');

    // ctrls
    var ctrls = wrap.find('.ctrl');
    var prev = wrap.find('.prev');
    var next = wrap.find('.next');

    // run params
    var timer = null;
    var index = 0;
    var after = 0;

    setInterval(function(){      
      if(index>=content_lis.length){
        index=0;
      }
      content_lis.eq(index).animate({
        opacity:0
      });
      after=index+1>=content_lis.length?0:index+1;
      content_lis.eq(after).animate({
        opacity:1
      });
      index++;
    },500);

2.1.2 进阶常规功能：左右点击、定点点击、自动轮播

var wrap = $('.my-slide');

    // content
    var content_lis = wrap.find('.slide-wrapper li');

    // bottom box
    var btn_lis = wrap.find('.slide-box li');

    // ctrls
    var ctrls = wrap.find('.ctrl');
    var prev = wrap.find('.prev');
    var next = wrap.find('.next');

    var index = 0;
    var after = 0;

    var run = function () {
      timer = setInterval(function () {
        after = index + 1 >= content_lis.length ? 0 : index + 1;
        change.call(null, index, after);
        index = after;
      }, 2000);
    };

    run();

    btn_lis.each(function () {
      $(this).click(function () {
        after = $(this).index();
        change.call(null, index, after);
        index = after;
      });
    });

    prev.click(function () {
      after = index - 1 < 0 ? content_lis.length - 1 : index - 1;
      change.call(null, index, after);
      index = after;
    });
    next.click(function () {
      after = index + 1 >= content_lis.length ? 0 : index + 1;
      change.call(null, index, after);
      index = after;
    });

    ctrls.hover(function () {
      clearInterval(timer);
    }, function () {
      run();
    });

    function change(prev, next) {

      });
      content_lis.eq(next).stop().animate({
        opacity: 1
