我正在使用组件和服务 组件:
server_detail=[{Name : 'production',Id : 1},
{Name :'Attendance', Id : 2}];
服务:
CREATE TABLE myTable (
table_id INT NOT NULL,
firstColumn NVARCHAR(10),
secondColumn INT,
thirdColumn INT,
CONSTRAINT DEF_secColumn DEFAULT 0 FOR secondColumn
)
我从路由获取Id并希望获取与该服务器Id对应的服务器名称。
答案 0 :(得分:10)
您可以使用find()
方法找到具体值:
// by Id
let server = this.servers.find(x => x.Id === 1);
// or by Name
let server = this.servers.find(x => x.Name === 'production');
更新根据您的评论:
ngOnInit() {
this.servers = this.alldata.server_detail;
this.server_Id= this.route.snapshot.params['id'];
let server = this.servers.find(x => x.Id === this.server_Id);
if(server !== undefined) {
// You can access Id or Name of the found server object.
concole.log(server.Name);
}
}
如果找不到对象,则find()
方法将返回undefined
。
