Javascript AngularJS：单选按钮不是'；默认情况下未选中

我正在用angular对一些单选按钮进行编码，但我无法使其中一个收音机显示为标记为默认值。 这是我的代码：

<!-- language: lang-js -->

    //And this is the JavaSctipt:

    $scope.locationLookup = 1;
    $scope.updateDropdownValuesBreedingLocation = function() { // Change state for breeding
      // location radio
      $scope.dropdownValues = ($scope.localData.useFavorites) ? $scope.variableDefinition.possibleValuesFavorite : $scope.variableDefinition.possibleValues;
      $scope.locationLookup = 1;
    };

    $scope.updateDropdownValuesAllLocation = function() { // Change state for all locations radio
      $scope.dropdownValues = ($scope.localData.useFavorites) ? $scope.variableDefinition.allFavoriteValues : $scope.variableDefinition.allValues;
      $scope.locationLookup = 2;
    };

<!-- language: lang-html -->
<!-- show-setting-form-element-new.html  -->
    <div ng-switch="widgetType">
    <div ng-switch-when="DROPDOWN">
        <input type="hidden" ui-select2="dropdownOptions" class="form-control select2" ng-model="valuecontainer[targetkey]" value-as-object="false" ng-change="changefunction()" ng-disabled="blockInput"/>
        <div ng-if="isLocation">
            <div class="possibleValuesDiv">
                <input type="radio" ng-disabled="blockInput"
                 ng-model="locationLookup" value=1 ng-change="updateDropdownValuesBreedingLocation()"> &nbsp;
                <span th:text="#{show.breeding.location}">Breeding locations</span> &nbsp;
                <input type="radio" ng-disabled="blockInput" 
                ng-model="locationLookup" value=2 ng-change="updateDropdownValuesAllLocation()"> &nbsp;
                <span th:text="#{show.all.location}">All locations types</span>
            </div>
            <div class="possibleValuesDiv">            
                <input type="checkbox" ng-model="localData.useFavorites" ng-checked="true" ng-change="updateDropdownValuesFavorites()"> &nbsp;
                <span th:text="#{show.favorite.location}">Show only favorite locations </span> &nbsp;
            </div>
        </div>
        <div ng-if="isBreedingMethod" class="possibleValuesDiv">
            <!--TODO : handle rendering of breeding method dropdowns for completeness-->
        </div>
    </div>
    <div ng-switch-when="NTEXT">
        <input type="text" ng-disabled="blockInput" valid-decimal="" class="form-control numeric-input" ng-model="valuecontainer[targetkey]" ng-change="changefunction()"/>
    </div>
    <div ng-switch-when="SLIDER">
        <input type="text" ng-disabled="blockInput" valid-decimal="" class="form-control numeric-input" ng-model="valuecontainer[targetkey]" ng-change="changefunction()"/>
    </div>
    <div ng-switch-when="CTEXT">
        <input type="text" ng-disabled="blockInput" class="form-control character-input" ng-model="valuecontainer[targetkey]" ng-change="changefunction()"/>
    </div>
    <div ng-switch-when="TEXTAREA">
        <textarea ng-disabled="blockInput" class="form-control character-input" rows="3" ng-model="valuecontainer[targetkey]" ng-change="changefunction()"/>
    </div>
    <div ng-switch-when="DATE">
        <input type="text" ng-disabled="blockInput" placeholder="yyyy-mm-dd" class="form-control date-input" ng-model="valuecontainer[targetkey]" jq-datepicker="true" with-image="true" image-src="/Fieldbook/static/img/calendar.png" ng-change="changefunction()"/>
    </div>
</div>

<!-- end snippet -->

//这是JavaSctipt：
$scope.locationLookup=1；
$scope.updateDropdownValuesBreedingLocation=function（）{//更改繁殖状态
//定位无线电
$scope.dropdownValues=（$scope.localData.useFavorites）？$scope.variableDefinition.PossibleValuesAvorite:$scope.variableDefinition.possibleValues；
$scope.locationLookup=1；
};
$scope.updateDropdownValuesAllLocation=function（）{//更改所有位置的状态
$scope.dropdownValues=（$scope.localData.useFavorites）？$scope.variableDefinition.allFavoriteValues:$scope.variableDefinition.allValues；
$scope.locationLookup=2；
};
繁殖地点
所有位置类型
仅显示最喜爱的位置

容器是这样的：

<!-- language: lang-html -->
    <section-container th:attr="heading=#{trial.managesettings.trial.environment.specify.level}">
        <div name="content">

你能帮我吗？

最有趣的是，如果我把这些收音机放在桌子外面，它工作得很好！但不是在里面

这段代码似乎运行良好。我们能否获得您所面临问题的更多全貌和最小可复制示例？显示的代码应该可以工作，但是如果您涉及子作用域，则必须在ng model中使用对象。不要打破“在ng模型中始终有一个点”的黄金法则@charlietfl或切换到“controller as”语法。我很惊讶有多少人不知道/不使用“controller as”-我想问题是这段代码被放入了一个表标记中。除了这个表之外，我还使用了这个代码，它工作得很好。
