vue项目实战之圆柱状水波效果实现
作者：coderSlow
最近工作中实现的一个效果不错,分享给大家,下面这篇文章主要给大家介绍了关于vue项目实战之圆柱状水波效果实现的相关资料,文中通过示例代码介绍的非常详细,需要的朋友可以参考下
1、先在data中定义有关参数和引入数据请求接口
1、字data中定义需要用到的参数
specialList: [
{ value: 0, height: 0, markKey: '' },
{ value: 0, height: 0, markKey: '' },
{ value: 0, height: 0, markKey: '' },
{ value: 0, height: 0, markKey: '' }
]2、引入数据请求接口
import { getMarks } from '@/api/businessOpetation'
2、再进行真实数据的获取
created() {
getMarks(22).then((res) => {
console.log(res)
if (res.code === 200) {
res.data.result.forEach((item, index) => {
const value = JSON.parse(item.markValue).value || 0
const height = 126 - 126 * (1 - value * 0.01)
const obj = {}
obj.markKey = item.markKey
obj.value = value
obj.height = height
this.$set(this.specialList, index, obj)
})
}
})
},3、核心代码（主要是html和CSS代码）
HTML代码：
<div class="box1">
<div
class="box1-item"
v-for="(item, index) in specialList"
:key="index">
<div class="img-box">
<div class="lui-column-bg">
<img
:src="require('@/assets/images/business/cylinder_bg.png')"
alt=""/>
<span class="item-value" :style="{ opacity: item.value }">{{
item.value
}}</span>
<div
class="lui-inner"
:class="['lui-inner' + index]"
:style="{ height: (item.height || 0) + 'px' }">
<div
v-show="item.height > 0 && item.height < 142"
class="gif-box"
:class="[`gif-box${index}`]"
></div>
</div>
</div>
</div>
<span class="box1-adderss" :class="[`box1-adderss${index}`]">{{
item.markKey
}}</span>
</div>
</div>CSS代码块：
.box1 {
width: 100%;

}4、需要的图片素材
需要用到9张png图片和4张gif图
5、最终效果
说明：图片截的是静态图片，现实柱状图是有水波的
