我从API获取Json数据。我想在Carousel滑块中显示数据。我尽力显示但没有找到结果。我是angular 2.的新用户。我知道用于显示的Interpolation {{}}符号，但我添加了数据以便理解这是我的HTML文件：
<div class="carousel slide media-carousel" id="media2">

在脚本文件类型中。
indexmobileshelf = [];
constructor(private _employeelist : SubServices){
}
ngOnInit()
{
this._employeelist.MobileShelf()
.subscribe(data => this.indexmobileshelf = data);
}
我添加了文件..一个servive是从我的类型脚本文件中调用的，其中有一个namr MobileShelf（）返回 indexmobileshelf 中的Json数据，然后我使用这些数据显示在轮播滑块中。请帮助我

你可以为所有重复元素使用循环* ngFor
假设您要显示数组的项目。 你的代码有点混乱阅读。但你可以理解这个概念并相应地应用
<div class="col-md-3 text-center slider_Itm" *ngFor="let mobile of indexmobileshelf">
<div style="height: 160px; width: 264px; background: linear-gradient(rgba(0, 0, 0, 0.2), rgba(0, 0, 0, 0.2)), rgba(0,0,0,0.2) url('app/images/Assets/mob1.png') no-repeat center;"></div>
<div class="slider_cntnt" style="margin-left: >
<p class="slider_Prod_name">{{mobile.Brand_id}}
<p class="slider_Prod_city">{{mobile.Brand_name}}</p>
<p class="slider_Prod_price">{{mobile.somethingelse}}</p>
</div>
</div>
