Html 如何使用@input将数组数据传递给子组件

我想使用@Input和selector将数据传递给子组件

HomeComponent.html

   <c:homeHeader [dataSample]="[homeDataSample]"></c:homeHeader>
   <c:homeMedia></c:homeMedia>
   <c:ourPartner></c:ourPartner>
   <c:ourFriends></c:ourFriends>

子组件

HomeHeader.html

    <h5 class="text-uppercase font-weight-bold"> 
     {{dataSample['title']}}
    </h5>

我的JSON文件仅复制haft

              "inlink_title": null
            }
          }
        },

如果我想为我的孩子html HomeHeaderComponent获取title=PERSONAL，我应该怎么做

我已经试了几个小时了，没什么好看的。

试着这样：

<c:homeHeader [dataSample]="homeDataSample"></c:homeHeader>

试着这样做：

<c:homeHeader [dataSample]="homeDataSample"></c:homeHeader>

试一试：

<c:homeHeader [dataSample]="homeDataSample"></c:homeHeader>

将dataSample类型更改为HomeHeader.ts中的任意类型，因为您正在将对象传递给子组件。如果您有任何特定类型，请使用该类型

@输入数据示例：任意；//

尝试访问html中的title属性，如下所示：

{{dataSample.assets[0].langs.en_US.title}

试一试：

<c:homeHeader [dataSample]="homeDataSample"></c:homeHeader>

看起来你基本上明白了。不过，您可以删除输入周围的[]。假设您所做的console.log正在返回您期望的值。如果没有，请链接它的输出，这样我们可以进一步帮助。看起来你基本上已经得到了它。不过，您可以删除输入周围的[]。假设您所做的console.log正在返回您期望的值。如果没有，请链接它的输出，这样我们可以进一步帮助。
