如果我有这个数组:
array = [
{
img: [
{0: 'http://hairsalonfurniture.eu/wp-uploads/750x480_how-to-create-a-nice-hair-salon-s-reception-gjzd.jpg',},
{1: 'http://hairsalonfurniture.eu/wp-uploads/750x480_how-to-create-a-nice-hair-salon-s-reception-gjzd.jpg',},
],
}
{
img: [
{0: 'http://hairsalonfurniture.eu/wp-uploads/750x480_how-to-create-a-nice-hair-salon-s-reception-gjzd.jpg',},
{1: 'http://hairsalonfurniture.eu/wp-uploads/750x480_how-to-create-a-nice-hair-salon-s-reception-gjzd.jpg',},
],
}
]
如何用HTML显示它?我知道如何显示一个img(如果它是img):'url'看起来像这样;
this.imgs = this.myprovider.getArray();
HTML:
<div ngfor="let item of imgs">{{item.img}}</div>

由于img
对象数组中的键是从0开始的数字,因此您可以使用循环索引访问值:
<ul>
<li *ngFor="let item of array">
<ul>
<li *ngFor="let image of item.img; let i = index">
<img src="{{ image[i] }}" />
</li>
</ul>
</li>
</ul>
由于某些原因,Stack Blitz不想加载图像URL,但是从输出中可以看到,HTML是正确的:https://stackblitz.com/edit/nested-array-example

尝试
<div ngfor="let item of imgs">{{item.img.toString()}}</div>
或
<div ngfor="let item of imgs">
<div ngfor="let img of item.img">{{img}}</div>
</div>

您可以以嵌套方式迭代两次-
<ng-container ngfor="let childImages of imgs">
<div ngfor="let item of childImages">{{item.img}}</div>
<ng-container>
注意:您应该使用html元素,而不是其他任何html元素,否则它将扭曲html的外观。

</div>
