Angular4通选择值这么一个旋转木马会出现

问题描述 投票:1回答:1

我有不同的橄榄球队一个选择。当我点击一个团队,我想转盘与俱乐部的球员出现。我已经从存储在数据库中。

我设法得到期权的价值,但转盘将显示所有玩家不但选择俱乐部的。这个问题绝对是打字稿文件,在功能,因为我不能转盘连接到所选俱乐部。请帮我,我将不胜感激。

你可以这样说:你应该根据自己的选择填充您players变量

selectOption() {
    var inputValue = this.club_IDClub;
    this.players = this.players.filter(x => x.ClubID == inputValue);
}
