javascript - 计算整体重要性。 Angular 型

Question

考虑示例:http://jsfiddle.net/KWLu7/16/

我正在尝试将总体重要性值计算为每个选定选择重要性的总和乘以其父标准重要性:

var watch = $scope.$watch("prioritizationProfile", function() {
    $scope.overallImportance = 0;

    for(var j = 0; j < $scope.prioritizationProfile.length; j++) {
        var criterionGroup = $scope.prioritizationProfile[j].criterionGroup;

        for(var i = 0; i < criterionGroup.length; i++) {

            var criterionChoices = criterionGroup[i].choices;

            for(var k = 0; k < criterionChoices.length; k++) {
                console.log(criterionChoices[k]);
                if(criterionChoices[k].selected) {
                    $scope.overallImportance += 
                        criterionChoices[i].importance * 
                        criterionGroup[i].importance;
                }
            }
        }
    }
}, true);

如果您尝试一下，您会发现最大值始终为 22。我在这里做错了什么？

Answer 1

您在 prioritizationProfileWatch 的内部 for 循环中使用了错误的索引

改变

$scope.overallImportance += criterionChoices[i].importance * criterionGroup[i].importance;

到

$scope.overallImportance += criterionChoices[k].importance * criterionGroup[i].importance;
