益盛:图片轮播_js代码分享

建站知识

有些人想要自己的网页炫一点,高大上一点,做一些图片轮播的效果,但是自己又不太会弄, 因为这些图片轮播代码是涉及到代码应用的, 对于新手来说还是有一点难度的, 所以今天给大家介绍一下图片轮播js代码怎么写:

页面中已经存在名为imgPlayer(或者别的ID也行)的节点.
PImgPlayer.addItem( “test”, “http://www.pomoho.com”, “http://static.pomoho.com/static/samesong/images/logo5.jpg”);
PImgPlayer.addItem( “test2”, “http://www.pomoho.com.cn”, “http://static.pomoho.com/static/samesong/images/logo4.jpg”);
PImgPlayer.addItem( “test3”, “http://www.pomoho.com.cn”, “http://static.pomoho.com/static/samesong/images/logo3.jpg”);
PImgPlayer.init( “imgPlayer”, 200, 230 );
备注:
适用于一个页面只有一个图片轮播的地方.
