在下方提供的视图中，我正在尝试根据当前ng-repeat对象（用户）中可用的键（colorId），在下拉框中选择一个值。 有人知道如何做到这一点吗？
<div ng-app>
<div ng-controller="MyCntrl">
<table>
<thead >
<tr>
<th width="50%">User</th>
<th width="50%" >Color</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="user in users">
<td width="50%">{{user.name}}</td>
<td width="50%">
<select ng-model="user.colorid" ng-options="color.name for color in colors">
<option value="">Select color</option>
</select>
</td>
</tr>
</tbody>
</table>
</div>
</div>
控制器代码为：
'use strict';
angular.module('nes',)
.controller('MyCntrl',['$scope',function ($scope) {
$scope.colors = [
{id:'1', name:'blue'},
{id:'2', name:'white'},
{id:'2', name:'red'}
];
$scope.users = [
{ name:'user1',colorId:'1'},
{ name:'user2',colorId:'2'}
];
}]);
