选择选项数据绑定角度4

使用select选项显示数据时遇到问题: 在控制台中没有显示错误和显示数据,但屏幕用户没有任何事情发生:

查看

if( wanting child to exit )
{
    int status;
    fprintf(stderr, "game_over\n"); //ENDS CHILD
    wait( &status );
    return 0;
}

fprintf( stderr, "next command to child\n" );
read(fds[PIPE_READ], buff, sizeof(buff));

成分:

HTML:

<select id="genero" class="form-control" #genero="" >
        <option value="">Please Select</option>
        <option *ngFor="let genero of generos" [ngValue]="genero">{‌{genero.name}}</option>
</select>

服务:

export class:

public geneross: Generos[];



ngOnInit() {

this._generoService.getGeneros(this.token).subscribe(
response => {

this.generos = response.generos;



});
}

如果我使用:

getGenereos(token){

let headers = new Headers({
'Content-Type':'application/json',
'Authorization':token
});

return this._http.get(this.url+'generos/', { headers: headers })
.map(res => res.json());
}
列表是可行的,但选择选项不起作用
