复制代码 代码如下:
$(function () {
var page = 1;//初始化page变量
var i = 2;//每版放两组图片
var $pictureShow = $(".pictures4");
var downwidth = $pictureShow.width();//获取框架内容的宽度，既每次移动的大小
var len = $(".picturescontent4").find('ul').length;//找到一共有几组图片
var page_number = Math.ceil(len / i);//找到一共有多少个版面
$("#symbol4b").click(function () {
if (!$(".picturescontent4").is(":animated")) {//判断是否正在执行动画效果
if (page == page_number) {//已经到最后一个版面了,如果再向后，必须跳转到第一个版面。
$(".picturescontent4").animate({ left: '0px' }, "slow");//通过改变left值，跳转到第一个版面
page = 1;
} else {
$(".picturescontent4").animate({ left: '-=' + downwidth }, "slow");//通过改变left值，达到每次换一个版面
page++;
}
}
return false;
});
$("#symbol4a").click(function () {
if (!$(".picturescontent4").is(":animated")) {
if (page == 1) {//已经到第一个版面了,如果再向前，必须跳转到最后一个版面
$(".picturescontent4").animate({ left: '-=' + downwidth * (page_number - 1) }, "slow");//通过改变left值，跳转到最后一个版面
page = page_number;
} else {
$(".picturescontent4").animate({ left: '+=' + downwidth }, "slow");//通过改变left值，达到每次换一个版面
page--;
}
}
return false;
});
});
