需求:等高瀑布流+下拉加载+点击图片放大
老板发布一个需求,需要做一个等高瀑布流图片展示,
What?这么简单,还不是随随便便弄个插件就好了,在试过vue-waterfall、vue-waterfall-easy、vue-waterfall2后,我发现多多少少不能迎合需求,所以决定自己手写。
=====================================================>
下面代码:(小伙伴们根据自己需求提取,也可以使用插件,毕竟方便,注意我的是等高瀑布流不是等宽!)
图片查看用的是viewer插件,传送门:viewer
2020-10-14修改:viewer图片没有形成图片数组,无法上下翻页
HTML:
//图片显示区域
<div id="content">
<viewer :images="imgList" class="Mywaterfall" >
<div class="image-content" v-for="(img,index) in imgList" :key="index">
<img :src="img.url"/>
</div>
</viewer>
</div>
//回到顶部按钮
<el-backtop target="" :bottom="70">
<el-tooltip content="回到顶部" placement="bottom" effect="light">
<div class="backtop-div">
<i class="el-icon-caret-top"></i>
</div>
</el-tooltip>
</el-backtop>
JS:
methods: {
getImg(){
this.request.get('/getImg').then((res)=>{
this.imgList=res.data
})
},
getImgList(){
this.request.get('/addImg').then((res)=>{
res.data.forEach((item)=>{
this.imgList.push(item)
})
})
}
},
created() {
this.getImg()
},
mounted() {
let _this = this;
window.onscroll = function(){
let scrollTop = document.documentElement.scrollTop||document.body.scrollTop;
let windowHeight = document.documentElement.clientHeight || document.body.clientHeight;
let scrollHeight = document.documentElement.scrollHeight||document.body.scrollHeight;
if(scrollTop+windowHeight == scrollHeight){
//滑动底部加载更多图片
_this.getImgList()
}
}
}
},
css(重点)
.Mywaterfall {
display: flex;
flex-wrap: wrap;
}
.image-content {
margin: 5px;
flex-grow: 1;
}
.Mywaterfall img{
display: block;
min-width: 100%;
height: 200px;
object-fit: cover;
}
.Mywaterfall img:hover{
transform:scale(1.05);
transition:all .3s linear;
cursor: pointer;
}
/* 回到顶部-CSS*/
.el-backtop{
background: #5485fc !important;
color: white !important;
border-radius: 0 !important;
width: 50px !important;
height: 50px !important;
}
.backtop-div{
width: 100%;
height: 100%;
text-align: center;
line-height: 50px;
}
.el-backtop, .el-calendar-table td.is-today{
color: #5485fc;
}
贴两张效果图,加载动画我没贴出来,自己手写喔
