以preselected价值角度NG选项按对象ID [英] angular ng-options with preselected value by object id

问题描述

有没有一种方法如下选择可以有一个 pre-选择俱乐部？

Is there a way the following select can have a pre-selected club ?

<select ng-model="c.pilot.clubIdx" ng-options="club.idx as club.name for club in c.clubs track by club.idx">

c.pilot.clubIdx = 2

c.clubs = {{IDX：1，名称：club1}，{IDX：2，名称：club2}}

c.pilot.clubIdx = 2
c.clubs = { {idx: 1, name: "club1"}, {idx: 2, name: "club2"} }

在选择菜单应显示club2。

The select-menu should show "club2".

由于俱乐部都存储在一个数据库，并可以改变，我喜欢他们只保留为 引用的飞行员。

Since the clubs are stored in a db and can be altered, I like to keep them only as references on the pilots.

解决：通过去掉解决了跟踪问题

SOLVED: removing track by solves the problem.

推荐答案

。喜欢的东西： $ scope.c.pilot.clubIdx = 2 或 $ scope.c.pilot.clubIdx = $ scope.c.clubs [1 ] .IDX
