我对 ng-select 有一个独特的问题。我有多个选择框填充了相同的 $scope.list （这是一个重要的要求）。

这些项目只能在一系列下拉列表中选择一次。我无法实现这一点 - 因为删除 $scope.list 会从前一个选择框中删除该项目。

<div ng-repeat="element in anotherList">
    <select ng-options="o for o in list" ng-model="abc" required>
 </div>

我最终使用 ng-repeat 和 ng-disabled

应用程序.js

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {
  $scope.name = 'World';
  $scope.b  = [1, 2, 3];
  $scope.list = ["Quora", "SOf", "Wikipedia", "Google", " Wolfram Alpha"];

  $scope.isDisabled = {
    "Quora": false,
    "SOf": false,
    "Wikipedia": true,
    "Google": false,
    "Wolfram Alpha": false
  };
  $scope.updateDisabled = function(model){
    $scope.isDisabled[model] = !$scope.isDisabled[model];
  }
});
