我正在使用ionic2。我有product
的数组。我正在使用网格视图显示产品。
<ion-row *ngFor="let i of rows" #myElem>
<ion-col class="productlist" col-6 *ngFor="let p of product | slice:(i*2):(i+1)*2" (click)="nav(p.details.id)" >
<div class="product-image">
<img src="{{p.details.P_IMAGES[0].URL}}" alt="Product 1">
</div>
<div class="product-blk">
<div class="product-title">{{p.details.P_TITLE}}</div>
<div class="product-price">
<img src="./assets/images/rupee-yellow.svg" alt="Rupee">{{p.details.PRICE_SALE}}
<span>{{p.details.PRICE_REGULAR}}</span>
</div>
<div class="product-desc">
{{p.Desc}}
</div>
</div>
</ion-col>
</ion-row>
这是我的CSS:
.productlist {
animation: FadeIn 1s linear;
animation-fill-mode: both;
animation-delay: .5s
}
@keyframes FadeIn {
0% {
opacity: 0;
transform: scale(.1);
}
85% {
opacity: 1;
transform: scale(1.05);
}
100% {
transform: scale(1);
}
}
它完美无缺,但我需要在每个网格上设置动画延迟;我需要一个像这样的自定义CSS类:
.productlist:nth-child(1),.productlist:nth-child(2),..
我该怎么做?
答案 0 :(得分:1)
这是您需要的CSS:
.productlist:nth-child(1) {
animation-delay: 1s;
}
.productlist:nth-child(2) {
animation-delay: 2s;
}
.productlist:nth-child(3) {
animation-delay: 3s;
}
.productlist:nth-child(4) {
animation-delay: 4s;
}
为简洁起见,您可以在像Sass这样的CSS预处理器中编写for循环:
@for $i from 1 through 4 {
.productlist:nth-child(#{$i}){
animation-delay: $i + s;
}
}
