transition 平移属性实现 横向整屏 滚动
需要达到效果:
- 横向展示商品,默认一行展示5个,超出隐藏,页面一打开,该模块自动横向滚动
- 有前进后退按钮,默认隐藏,鼠标移入显示,且动画停止;鼠标移出按钮隐藏,动画重启
效果展示: (由于是截图拼接成的gif, 滚动效果未能展示出来,正常滚动是5s后发生,且很顺滑)
实现原理:
1. 使用css3 的 transition 过渡属性完成动画,使动画盒子脱标(脱离标准流), 不影响其他布局, 且方便通过 left 属性进行动画
具体就是通过在发生动画的盒子里修改行内属性 left 值,进而发生动画
2. 使用 cubic-bezier 控制变化的速度曲线
实现代码:
HTML:
<template> <div class="hotSalesGoods_container"> <div class="hot_sale_product_box" v-if="hotSaleProductList.length"> <section class="w mt30 clearfix"> <div class="module_box module_box2"> <div class="title"> <div class="left"> <span>1F</span> 热销商品 </div> </div> <div class="mall_good_box hot_product_btn_box" @mouseenter="hoverTimer()" @mouseleave="outTimer()" > <div class="mall_good_inner" :style="{'left': -(swiperConfig.index * (swiperConfig.width +16)) +'px'}" > <hotMallGoods :msg="iitem" :index="j" v-for="(iitem,j) in hotSaleProductList" :key="j+'key'" ></hotMallGoods> </div> <i class="hot_product_btn_left cursor" @click="prevPage()"></i> <i class="hot_product_btn_right cursor" @click="nextPage()"></i> </div> </div> </section> </div> </div> </template>

贝塞尔曲线:
cubic-bezier(<x1>,<y1>,<x2>,<y2>), 其实是用4个点确定速度曲线,已知 两个点 (0,0) (1,1) ,我们通过 x1,y1 x2,y2 坐标来控制另外两个点,从而确定速度曲线
