angular怎么实现多个select下拉框，选中当前某一项，其他下拉框去掉选中的值

[jadeee123]

大概就是图片上这样的效果

我的代码

<div ng-controller="DemoCtrl">
	<div class="form-group col-md-12" ng-repeat="item in arrayList">
                <div class="col-md-6">
                	<label class="col-md-3">
	                    <span>{{item.type}}:</span>
	                </label>
	                <div class="col-md-9">
	                    <select class="form-control" ng-model="item.age" ng-change="change()" 
	                    		ng-options="option.age as option.name for option in selectList">
			                <option value="">--选择--</option>
			            </select>
	                </div>
                </div>
        </div>
</div>

        angular.module('demo', []);
		angular.module('demo').controller('DemoCtrl', function($scope, $window) {
			$scope.arrayList = [
				{name: '下拉1',id: '11'},
				{name: '下拉2',id: '22'},
				{name: '下拉3',id: '33'},
				{name: '下拉4',id: '44'},
				{name: '下拉5',id: '55'}
			]
			
			$scope.selectList = [
				{name: '选择1',age: '11'},
				{name: '选择2',age: '12'},
				{name: '选择3',age: '13'},
				{name: '选择4',age: '14'},
				{name: '选择5',age: '15'}
			]
		}
