属性

属性说明
@Input()
ngTemplateOutletContext: Object | null

A context object to attach to the EmbeddedViewRef. This should be an object, the object's keys will be available for binding by the local template let declarations. Using the key $implicit in the context object will set its value as default.

@Input()
ngTemplateOutlet: TemplateRef<any> | null

A string defining the template reference and optionally the context object for the template.

说明

你可以通过设置 [ngTemplateOutletContext] 来给 EmbeddedViewRef 附加一个上下文对象。 [ngTemplateOutletContext] 是一个对象,该对象的 key 可在模板中使用 let 语句进行绑定。

You can attach a context object to the EmbeddedViewRef by setting [ngTemplateOutletContext]. [ngTemplateOutletContext] should be an object, the object's keys will be available for binding by the local template let declarations.

<ng-container *ngTemplateOutlet="templateRefExp; context: contextExp"></ng-container>
      
      <ng-container *ngTemplateOutlet="templateRefExp; context: contextExp"></ng-container>
    

在上下文对象中使用 $implicit 这个 key 会把对应的值设置为默认值。

Using the key $implicit in the context object will set its value as default.
