在我的应用中,我正在这样做:
<ion-col *ngFor ="let place of intentList, let photo of photoList">
<ion-card>
<ion-card-content>
<img class="img" src = "{{photo}}" (click)="clickedImage(place.intent)">
<div>{{place.val}}</div>
</ion-card-content>
</ion-card>
</ion-col>
数组photoList包含具有不同照片URL的字符串。这是数组:
this.photoList = ["./assets/images/001-breakfast.png", "./assets/images/002-brunch.png", "./assets/images/003-sandwich.png",
"./assets/images/004-food.png", "./assets/images/005-dinner.png", "./assets/images/006-cake.png", "./assets/images/007-cocktail.png"]

<ion-col *ngFor ="let place of intentList; let i=index;">
<ion-card>
<ion-card-content>
<img class="img" src = "{{photo[i]}}" (click)="clickedImage(place.intent)">
<div>{{place.val}}</div>
</ion-card-content>
</ion-card>
</ion-col>
您可以使用索引来实现:

这是因为您不能成角度地运行2个循环。因此,实际上您无法在可变照片中获得照片路径的价值。 但是,相反,您是在可变照片中获得可变位置的值。
您可以检查它是否打印照片的值
{{photo}}
