将参数传递给子组件Angular

Question

当我从父对象传递对象到子组件时 - 它转换为字符串

<m-tank-add fuelTypes="{{this.fuelTypes}}" count="{{count}}"></m-tank-add>
 @Input() fuelTypes: Array<FuelTypeModel>;
 @Input() count: number;

count来自"5"和fuelTypes作为"[object Object],[object Object],[object Object],[object Object],[object Object]"

如何传递参数以便它们不会转换为字符串？

Answer 1

您应该通过方括号使用属性绑定，因为插值是字符串化的：

[fuelTypes]="fuelTypes"
