我发现了一个我不知道如何解决的问题。
如果您使用此模板,那么没有问题:
<li *ngFor="#supplier of supplierList | async">
<a (click)="changeSupplier($event)">
<span>{{supplier.id}}: {{supplier.name}}</span>
</a>
</li>
输出例如:
<li>
<a>
<span>1: Sony</span>
</a>
</li>
<li>
<a>
<span>2: Samsung</span>
</a>
</li>
如果我编辑模板并尝试将“supplier.id”设置为html属性“data-supplierid”:
<li *ngFor="#supplier of supplierList | async">
<a (click)="changeSupplier($event)" data-supplierid="{{supplier.id}}">
<span>{{supplier.name}}</span>
</a>
</li>
出现错误:
Can't bind to 'supplierid' since it isn't a known native property ("i>
<li *ngFor="#supplier of supplierList | async">
<a (click)="changeSupplier($event)" [ERROR ->]data-supplierid="{{supplier.id}}">
<span>{{supplier.name}}</span>
</a>

默认为属性绑定。对于属性绑定,请使用
attr.data-supplierid="{{supplier.id}}"
或
[attr.data-supplierid]="supplier.id"
