最近在刷网易云音乐歌单时发现首页的轮播图很有意思,正好自己想尝试做一个PC版的网易云音乐,于是就是使用Vue去做这个demo,废话少说,我要出招了,接招吧
页面的DOM结构
Slider-container的样式(Stylus)
.slider-container
width: 100%
height: 100%
text-align: center
padding: 10px 0
position: relative
这个子组件主要分为两块。
第一块、轮播图,其中它们的业务逻辑是
自动切换
左右icon切换轮播图
点击前后轮播图切换轮播图
鼠标滑动到轮播图停止轮播,离开后继续轮播
Slider-content的DOM结构
Slider-content的样式(Stylus)
.slider-content
position: relative
width: 100%
height: calc(100% - 20px)
left: 0%
top: 0%
margin: 0px
padding: 0px
background-size: inherit
.slider
position: absolute
margin: 0
padding: 0
top: 0
left: 50%
width: 65%
height: 100%
transition: 500ms all ease-in-out
background-color: #fff
background-repeat: no-repeat
background-position: center
background-size: inherit
transform: translate3d(-50%,0,-80px)
z-index: 1
&:before
position: absolute
content: ""
width: 100%
height: 100%
top: 0
left: 0
background-color: rgba(0, 0, 0, 0)
transition-delay: 100ms!important
transition: all 500ms
cursor: pointer
&.active
transform: translate3d(-50%, 0, 0)
z-index: 20
&.prev
transform: translate3d(-75%, 0, -100px)
z-index: 19
&.next
transform: translate3d(-25%, 0, -100px)
z-index: 18
i
width: 17.5%
display: none
position: absolute
top: 40%
font-size: 22px
color: rgba(255, 255, 255, 0.5)
text-shadow: 0 0 24px rgba(0, 0, 0, 0.3)
cursor: pointer
z-index: 21
&:first-child
left: 0
&:last-child
right: 0
&:hover
i
color: rgba(255, 255, 255, 0.8)
display: block
&.mask
.slider
&.prev, &.next
&:before
background-color: rgba(0, 0, 0, 0.50)
第二块、底部的dot, 其中它们的业务逻辑是
当前轮播图对应位置的dot高亮
鼠标移动到相应的dot上切换对应位置的轮播图
Dots的DOM结构
:style="setActiveDot(index)"
@mouseover="currentIndex = index">
Dots的样式(Stylus)
.dots
width: 100%
height: 20px
span
display: inline-block
width: 20px
height: 2px
margin: 1px 3px
cursor: pointer
上面是页面的DOM结构和表现的实现代码,接下来我们要讲的是连招的实现,小心啦,我要摸眼W + R3了。
上面我们讲到轮播图的业务逻辑,接下来,我们就讲讲如何实现的的吧
自动轮播
play () {
this.pause();
if (this.autoPlay) {
this.timer = setInterval(()=>{
this.next();
}, this.interval)
}
}
暂停轮播
pause () {
clearInterval(this.timer);
}
Icon切换轮播图
next () {
this.currentIndex = ++this.currentIndex % this.list.length;
},
prev () {
this.currentIndex = this.currentIndex === 0 ? this.list.length - 1 : this.currentIndex - 1;
},
前后轮播图的切换轮播图
onClick (i) {
if (i === this.currentIndex){
this.$emit('sliderClick', i);
} else {
let currentClickClassName = this.sliderDomList[i].className.split(' ')[1]
console.log(currentClickClassName)
if (currentClickClassName === 'next') {
this.next()
} else {
this.prev()
}
}
}
dots轮播图的切换轮播图
这里比较简单,只需要设置它的鼠标事件即可
@mouseover="currentIndex = index"
