我对选项GET ALL有疑问。这是流程。
首先，当用户打开应用并想要选择位置时，他有angular-google-maps，所有位置都选择了标记。此外，用户已链接下拉选择（首先需要选择国家/地区，并且我在地图上显示该国家/地区的所有标记，然后根据所选国家/地区，我显示下一个下拉列表，其中包含所选国家/地区的状态，并仅显示该州的标记，以及相同的城市。）
所有标记都有信息框，我在其中放置按钮ADD TO CHART。点击ADD TO CHART时，我会在表格列表中显示带有标记ID的信息。
现在，我希望按钮全部显示并显示列表中的所有ID。但是，取决于所选择的下拉菜单，如果只选择国家并按下全部，我列出国家中的所有标记，如果选择状态并单击全部获取，请给我所有标记在该状态。
这是代码＆＃34;

这一切都很好，就像我期望的那样。唯一的问题是获取所有按钮。 这是html
<div class="narudzbe_lokacija">
<div class="col-lg-3 col-md-3 col-sm-6 col-xs-12">
<h5>Odabir lokacije</h5>
<div>
<label class="control-label col-lg-12 col-md-12 col-sm-12 col-xs-12">Country: </label>
<select id="country" class="form-control" ng-model="country" ng-options="country as country.name for country in countries track by country.id" ng-change="getState(); filterMarkersCountry()">
<option value='country_id'>{{country.name}}</option>
</select>
</div>
<div>
<label class="control-label col-lg-12 col-md-12 col-sm-12 col-xs-12">States</label>
<select id="state" class="form-control" ng-disabled="!country" ng-model="state" ng-options="state as state.name for state in states track by state.id" ng-change="getCity(); filterMarkersState()">
<option value='state_id'>{{state.name}}</option>
</select>
</div>
<div>
<label class="control-label col-lg-12 col-md-12 col-sm-12 col-xs-12">City</label>
<select id="city" class="form-control" ng-disabled="!state" ng-model="city" ng-options="city as city.name for city in cities track by city.id" ng-change="filterMarkersCity()">
<option value='city_id'>{{city.name}}</option></select>
</div>
<button ng-click="allSelectedbenches()">Get all</button>
<br />
<br />
</div>
我尝试制作plunker，但我的应用程序有许多安宁，并且很难做出实例
答案 0 :(得分：0)
这是我的解决方案。
$scope.myCartItems = [];
$scope.allSelectedbenches = function () {
if($scope.filteredCities !== undefined){
$scope.myCartItems = $scope.filteredCities;
}
if($scope.filteredStates !== undefined){
$scope.myCartItems = $scope.filteredStates;
}
if($scope.filteredCountries !== undefined){
$scope.myCartItems = $scope.filteredCountries;
}
};
检查是否未定义，并显示所选的下拉框。这里唯一的问题是，在第一次下拉时我需要选择国家，州和城市。 $ scope.myCartItems总是从国家返回一切...... Thnx
