原生小程序翻页效果轮播图的相关文章

【微信小程序】：实现轮播图3秒滚动

wxml模板:(数据一维数组) <scroll-view scroll-y="true"> <swiper autoplay="auto" interval="3000" duration="500"> <block wx:for="{{home_pics}}" wx:for-index="index"> <swiper-item> <

【前端】javascript+jQuery实现旋转木马效果轮播图slider

实现效果: 实现原理: 技术栈: javascript+jQuery+html+css 实现步骤: // 0. 获取元素 // 1. 鼠标放置到轮播图上,显示两侧的控制按钮,移开后隐藏 // 2. 为两侧控制按钮绑定事件(调用同一个方法,只有一个参数,true为正向旋转,false为反向旋转) 实现代码: <!DOCTYPE html> <html> <head> <title>旋转木马效果轮播图</title> <meta charset

原生js实现的3个小特效（时钟、轮播图、选项卡）

时钟: <p id="timeTxt"></p>  //将获取到的时间显示在timeTxt这里面        <button onclick="startTime()">关闭</button>        <!--时钟-->        function startTime(){  //创建startTime()函数            var today=new Date();  //定义一个对象

CSS3,3D效果轮播图

---恢复内容开始--- 大家还记得我昨天的3D拖拽立方体吗??我昨天还说过css还可以做轮播图,所以咱们今天就写一下,css的轮播图吧! ....这个轮播图主要是用CSS3里的transform的旋转属性来完成3D效果的,然后配合原生js的显示隐藏,达到了3D旋转轮播图的效果: <!DOCTYPE HTML> <html> <head> <meta http-equiv="Content-Type" content="text/ht

简单说说tab标签页和轮播图

准确的来说,一个页面能够独立的做出轮播图才算是刚步入前端世界.说轮播图之前先来说说标签页,.因为它比较简单,我的效果使用jquery来实现的,. 具体代码只有一点点,. var timeout; $(document).ready(function(){ $("#tabfirst li").each(function(index){ var liNode=$(this); liNode.click(function(){ timeout=setTimeout(function(){ $

原生js实现移动端Touch轮播图的方法步骤

Touch 轮播图 touch轮播图其实就是通过手指的滑动,来左右切换轮播图,下面我们通过一个案例,来实现下. 1. html 结构 结构上,还是用ul.li来存放轮播图片,ol.li来存放轮播小圆点: 2. 样式初始化 html的一些标签,都会有一些默认样式,比如body标签默认是有一个边距的,为了不影响美观,我们需要清除掉. ? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 /* 清除标签默认边距 */ body,ul,li,ol,im

jQuery淡入淡出效果轮播图

用JavaScript做了平滑切换的焦点轮播图之后,用jQuery写了个简单的淡入淡出的轮播图,代码没有做优化,html结构稍微有一些调整,图片部分用ul替换了之前用的div. html结构如下: <div id="container"> <ul class="pic"> <li><a href="javascript:;"><img src="DSC01627.jpg"

轮播图---左右切换无长滚动效果轮播图-中级难度版

左右切换无长滚动轮播图思路:首先设有全局变量position(确定当前图片是第几张),arr数组:存放图片地址,方向:direction, 及lis小圆点数组,prev,记录小圆点的前一个, moveBool是否进入运动函数等1.点击事件:点击左边的leftBn,设置direction="right",position--,在这要确定position不能超出数组长度范围, 超出要重新赋值,点击小圆点把小圆点的当前是lis数组中的第几个赋值给position,然后图片生成2.图片生成:图
