我正在使用ngListSelect依赖项来输出 http://nidhishkrishnan.github.io/ngListSelect/
这是自定义指令：

现在我想在左边和左边添加一个锚标记deselectall 右边，我在指令中做了两个函数作为
scope.deselectrightall = function(slt) {
scope.selectedListItems.slt=[];
};
scope.deselectleftall = function(av) {
scope.availableListItems.av=[];
};
slt 是右侧多选数据＆amp; av是左侧多选数据。但是这个功能对我不起作用
请帮助我......
答案 0 :(得分：0)
您应该将代码更改为此。
$scope.checkAll = function () {
if ($scope.selectedAll) {
$scope.selectedAll = true;
} else {
$scope.selectedAll = false;
}
angular.forEach($scope.Items, function (item) {
item.Selected = $scope.selectedAll;
});
