点击时发送* ngFor值作为参数 [英] Send *ngFor value as parameter on click

问题描述

我正在Angular 2中做一个小应用程序，正在显示一个包含一些数据的表，当我单击表时我想获取这些数据

I'm making a little application in Angular 2, I'm displaying a table with some data, I wanna get that data when I make a click on my table

代码如下:

HTML模板:

<tr *ngFor="let users of usersdata; let i = index">
     <td (click)="data(users.username)">{{users.username}}</td>
     <td (click)="data(users.email)">{{users.email}}</td>
     <td (click)="data(users.id)">{{users.id}}</td>
     <td (click)="data(users.roleId)">{{users.roleId}}</td>
</tr>

这是我的组件:

data(data: string) {
    this.selectedParam.emit(data);
    console.log(data);
}

当我单击时，出现此错误:

When i make click i get this error:

EXCEPTION: Error in .../userslist.component.html:22:16 caused by: self.parent._el_24 is not a function

推荐答案

使用[(ngModel)]将数据绑定到组件的两种方式.像下面一样

use [(ngModel)] to make two way binding of your data to your component. like below

<td [(ngModel)]="users.username" (click)="data(users.username)">{{users.username}}</td>

也尝试

//$event will hold value and other reference.
data($event: any) {

}

您可以在[]和()表示法的angular2侧获得更多参考

You can get more reference in angular2 side on [] and () notation
