Question

我有html如下。需要帮忙。我不是Angular的专长。

<tbody>       
        <tr  *ngFor="let data of employeeFilterLists">
            <td>{{data.Code}}</td>
            <td (click)="selectEmployee('{{data.Code}}')">{{data.FirstName}} {{data.LastName}}</td>
            <td>{{data.Salary}}</td>
        </tr>       
</tbody>

现在，我已经编写了组件方法来捕获值以从方法中调用另一个组件。

selectEmployee(mdData:string){
  console.log("Choose Model...."+ mdData);
}

我收到以下错误。

Uncaught Error: Template parse errors:

Answer 1

您应该删除selectEmployee方法中的{{}}

这是这样的：

<td (click)="selectEmployee(data.Code)">{{data.FirstName}} {{data.LastName}}</td>

希望这有帮助！
