javascript - 如何为两个连接的字符串分配值和范围

Question

我的 HTML 代码:-

<ul class="sub-menu collapse">
     <li ng-hide="abcMenuHide" ng-click="showModal('abcMaster')">
        <a>Add/update listOne</a></li>
     <li ng-hide="xyzMenuHide" ng-click="showModal('xyzMaster')">
        <a>Add/Update listTwo</a></li>
</ul> ... and so on

我试图隐藏 <li>基于分配给 ng-hide 的值的元素。我在这样的指令中设置这个值:-

$scope.menuListHide = function(){
        for (var group in $scope.data) {
            if (group != "sectionOne") {
                for (var list in $scope.data[group]) { 
                    for (var key in $scope.data[group][list]) { 
                        if ($scope.data[group][list].view != undefined) {
                            if (!$scope.data[group][list].view) {
                                $scope.(list+"MenuHide") = true; \\This assignment is wrong also I am not able to attach scope to it.
                            }
                        }
                        else if($scope.data[group][list][key].view != undefined){
                            if (!$scope.data[group][list][key].view) {
                                $scope.(key+"MenuHide") = true; \\This assignment is wrong also I am not able to attach scope to it.
                            }
                        }
                    }
                }
            }   
        }
    }

$scope.menuListHide();

有什么方法可以分配 $scope以及连接字符串的值？

Answer 1

而不是这个(语法不正确):

$scope.(list+"MenuHide") = true;

你需要这样做:

$scope[list + "MenuHide"] = true;

要动态更改对象内的属性，您需要将属性名称用 [] 括起来。并直接在对象上调用它。自 $scope这里是一个 JavaScript 对象，属性 list + "MenuHide"将被分配给true在$scope .
