形式單選按鈕引用時NG-模型改變舊的內存 - 符NG檢查

我：

<div class="filter-column"> 
    <div class="filter-title">Market</div> 
    <div class="bottom-line"></div> 
    <div class="overflow-container"> 
     <input type="radio" value="all" name="marketRadio" 
      ng-checked="true" class="resetAll" ng-model="filter.markets" 
      ng-change="radioMap('market')" checked>All 
     <div ng-repeat="choice in markets| orderBy: 'name'"> 
     <input type="radio" value="{{choice.name}}" name="marketRadio" 
      ng-change="radioMap('market')" ng-model="filter.markets" > 
     {{choice.description}} 
     </div> 
    </div>

在控制器中，我有：

var ppvFilter = { 
    regions: [], 
    markets: [], 
    dealers: [] 
    }; 



    $scope.$watchCollection(function() { 
    return ppvFilter; 
    }, 
    function(newValue) { 
     $scope.regions = newValue.regions; 
     $scope.markets = newValue.markets; 
     $scope.dealers = newValue.dealers; 
    });

當我使用ppvFilter.markets.length = 0; ppvFilter.markets = ppvFilter.markets.concat(['a', 'b', 'c'])以編程方式刷新單選按鈕列表（而不是頁面刷新）時，單選按鈕選項列表會更新，因爲它應該在gui中更新。但是，ng-checked="true"不再適用於all，並且在列表更新後未選中。

我懷疑這是因爲角度窗體引用了舊內存，即使它顯示了單選按鈕的新列表。
