图片轮播_html/css_WEB-ITnose

当滚动到第四张图片时,会快速滚到第三张,第二张,第一张图片
当我想轮播时,第四张轮播玩就滚到第一张,

回复讨论(解决方案)

看看这个咯

你轮播的时候是不是有个index值啊，在轮播到第四张的时候改为1

可以去看看 也是图片轮播的

你的要求只需把源文件 http://unslider.com/unslider.js 中第 116 行

if(!this.items.eq(index).length) index = 0;

修改一下就行了

我这里修改了 116 和 117 两行, 修改后如下

			if(!this.items.eq(index).length) {index = 0; cb = true;}			if(index < 0) {index = (this.items.length - 1); cb = true;}

效果演示: http://a7d.net46.net/unslider_mod.php

源文件中 这行

var speed = cb ? 5 : this.opts.speed;

中的 5 指动画时间只持续 5 ms, 已经极小了, 和直接切换的效果差不多了, 当然想要绝对 可以把它改成 0

改

if (!c.length)r = 0;if (r < 0)r = a.length - 1;

成

if (!c.length) {r = 0; i = true;}if (r < 0) {r = a.length - 1; i = true;} // 此行是控制右往左轮播到边缘的, 可以不改
