Question

我试图简单地使用* ngIf;否则渲染一个按钮但是不断出现此错误。看来我的ng-template上没有活动？事实并非如此。我必须做一些明显不对的事。

事件名称（单击）显然拼写正确，据我所知，我需要的所有指令浏览器和公共模块都被导入并列在NgModule元数据中。

错误：

嵌入式上的任何指令都不会发出事件绑定模板。确保事件名称拼写正确且全部指令列在“@ NgModule.declarations”中。

这是我找到的唯一真正的解决方案： Solution 1但我将BrowserModule和CommonModule都导入到AppModule中，并且模块最接近发生错误的位置。

非常接近只使用两个* ngIfs（工作正常）...为什么我的ng-template上没有事件？我用一个属性替换了changeViewState（），并将（click）事件更改为（activate）和（mouseover）事件...它似乎不像ng-template上的任何（事件）...

我在应用程序周围复制了问题代码并且每次都出错。

'问题代码'：

Answer 1

您可以将事件绑定到包装容器（e.x.HTML标签，ng-container）

＆＃13;

<ng-template #ele  >
 <div (click)="changeViewState('userInfo')" class="userManHover" [ngClass]="{'userManSelect': stateUserReq =='userInfo'}">
  ...
  </div>
</ng-template>

＆＃13;

ng-template上不能有活动？嵌入式模板上的任何指令都不会发出事件绑定点击
