用jquery实现带左右按键的轮播图

标签:over 12px ul li 按键 显示 nal 火影忍者 ansi 记录 成品如下: 简单来说就是点击“右”按钮时,转换到右边的下一幅图片,同时上面的小方块颜色也跟着改变,如果已经是最后一幅图片,再点击“右”,则转换到第一幅图片,是直接向左移找到第一幅图的,明天再做一下无缝切换的效果,即最后一幅图放完了以后第一幅图从右滑进来跟上。点击“左”同理。 下面是html代码 css代码: 在程序中,用page来记录是第几屏在展示,然后选择相应的小方块让它变蓝,并且计算为了移到下一屏应该怎样进行相对定位。在布局里还有一个小技巧,就是包裹内容区的div要比外层div长,这样内容(总共4屏)在里层排成一排,但外层只能显示出1屏。 用jquery实现带左右按键的轮播图 标签:over 12px ul li 按键 显示 nal 火影忍者 ansi 记录 原文地址:http://www.cnblogs.com/mengqi-S/p/7287233.htmlDOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
