知识点1: 进度条随数据变化,并添加渐变样式
效果图:
dom:
// 进度条
<div class="progress" :style="styleObj1"> <div class="point"></div> </div>
// 数据容器 <div class="precent"> <counter :data="precents1" :config="config2"></counter> </div>
css:
.progress{
width: 50%;
position: absolute;
height: 10px;
background: linear-gradient(to right,rgb(31,107,169),rgb(167,132,252)); //线性渐变
border-radius: 5px;
left: 20%;
bottom: 22px;
transition: all 2s; //css动画
.point{
width: 10px;
height: 10px;
border-radius: 50%;
background: #fff;
border: 2px solid rgb(173,133,255);
box-sizing:content-box !important;
position: absolute;
top: -2px;
right: 0px;
}
}
- js
export default{
computed:{
styleObj1(){
return{
width:`${this.precents1*3.1}px` //宽度变化
}
}
}
}
//接数据
loaddata() {
this.$http.indi.get('sl0057', {}, res => {
if (res.data.data && res.data.data.length > 0) {
try {
this.totalvalue1 = res.data.data[0].KPI_VALUE1
this.precents1 = res.data.data[0].KPI_VALUE2
} catch (error) {
console.log('**** indicator has error', error)
}
}
})
}
