Angularjs 控制器中基于模型的角度更新ng重复

我是个新手。我正在尝试使用ng repeat显示品牌列表。它工作得很好。但当我点击下一步按钮时，它也应该改变accorading数组索引。这对我不起作用。请帮我解决这个问题。并告诉最好的方法来构造这种类型的案例。我的代码在下面

var数据=[{“度量”：“度量1”，“风味”：[{“FlavorName”：“FlavorName1”，“TotalBrands”：[{“BrandName”：“Brand1”}，{“BrandName”：“Brand2”}，{“FlavorName”：“FlavorName2”，“TotalBrands”：[{“BrandName”：“Brand3”}，{“BrandName”：“Brand4”}]}]； var myApp=angular.module（“测量”，[]）

以前的
风味计数{{flavourCount}

度量值：{{surveyList[measureCount].Measure}

风味名称：{{Flavours[flavourCount].FlavourName}

所有品牌

{{brand.BrandName}

下一个
myApp.controller（“数据控制器”、[“$scope”、函数（$scope）{
$scope.name=“sajid”；
$scope.measureCount=0；
$scope.flavourCount=0；
$scope.surveyList=数据；
$scope.listLength=$scope.surveyList.length；
$scope.flavors=$scope.surveyList[$scope.measureCount].flavors；
$scope.totalBrands=$scope.flavours[$scope.flavourCount].totalBrands；
$scope.getPreviousMeasure=函数（）{
如果（$scope.measureCount==0）{
$scope.measureCount=0；
}否则{
$scope.measureCount=$scope.measureCount-1；
}
};
$scope.getNextMeasure=function（）{
如果（$scope.listLength-1==$scope.measureCount）{
$scope.measureCount=0；
}否则{
$scope.measureCount=$scope.measureCount+1；
}
};
$scope.getPreviousFlavor=函数（）{
如果（$scope.flavors==0）{
$scope.measureCount=$scope.measureCount-1；
$scope.flavourCount=0；
}否则{
$scope.flavourCount=$scope.flavourCount-1；
}
};
$scope.getNextFlavour=function（）{
如果（$scope.flavours.length==$scope.flavourCount）{
$scope.measureCount=$scope.measureCount+1；
$scope.flavourCount=0；
}否则{
$scope.flavourCount=$scope.flavourCount+1；
}
};

}]))

应该插入的GetPreviousFlavor和GetNextFlavor中的最后一行

$scope.totalBrands = $scope.flavours[$scope.flavourCount].TotalBrands;

这使totalBrands焕然一新

$scope.getPreviousFlavour = function(){

    if($scope.flavours === 0){
        $scope.measureCount = $scope.measureCount - 1;
        $scope.flavourCount = 0;
    }else{
        $scope.flavourCount = $scope.flavourCount -1;   
    }
    $scope.totalBrands = $scope.flavours[$scope.flavourCount].TotalBrands;
};

$scope.getNextFlavour = function(){
    if($scope.flavours.length  === $scope.flavourCount){
        $scope.measureCount = $scope.measureCount + 1;
        $scope.flavourCount = 0;
    }else{
        $scope.flavourCount = $scope.flavourCount + 1;  
    }
    $scope.totalBrands = $scope.flavours[$scope.flavourCount].TotalBrands;  
};

很抱歉，无法将示例数据添加到代码部分。我无法获取您的信息。你能用不同的方式解释吗。或者在代码中显示

$scope.getPreviousFlavour = function(){

    if($scope.flavours === 0){
        $scope.measureCount = $scope.measureCount - 1;
        $scope.flavourCount = 0;
    }else{
        $scope.flavourCount = $scope.flavourCount -1;   
    }
    $scope.totalBrands = $scope.flavours[$scope.flavourCount].TotalBrands;
};

$scope.getNextFlavour = function(){
    if($scope.flavours.length  === $scope.flavourCount){
        $scope.measureCount = $scope.measureCount + 1;
        $scope.flavourCount = 0;
    }else{
        $scope.flavourCount = $scope.flavourCount + 1;  
    }
    $scope.totalBrands = $scope.flavours[$scope.flavourCount].TotalBrands;  
};
