Javascript 如何在指令中使用$emit

这是我的控制器：

scope.Delete = function (index, selecteditemslist) {

    scope.selectedIndex = index;

    scope.$emit('removeOrg', {
        index: index
    });

    scope.$emit('removeRecipient', {
        index: index,
        type: 'orgs',
        selecteditemslist: selecteditemslist
    });
    scope.$emit('removeRecipient', {
        index: index,
        type: 'people',
        selecteditemslist: selecteditemslist
    });
};

如何解决这个问题？当我单击某个项目时，该特定项目只应被删除。请帮我解决这个问题。

如何调用

Delete

。。。您能检查一下

Delete

是否调用了3次Delete调用了一次，但在Delete中，所有三个$emit都触发了，我如何限制调用

removeCipient

的次数

scope.Delete = function (index, selecteditemslist) {

    scope.selectedIndex = index;

    scope.$emit('removeOrg', {
        index: index
    });

    scope.$emit('removeRecipient', {
        index: index,
        type: 'orgs',
        selecteditemslist: selecteditemslist
    });
    scope.$emit('removeRecipient', {
        index: index,
        type: 'people',
        selecteditemslist: selecteditemslist
    });
};

$scope.$on('removeRecipient', function (event, args) {
    $scope.index = args.index;
    $scope.selecteditemslist = args.selecteditemslist;
    console.info($scope.index);
    console.info($scope.selecteditemslist);
    $scope.type = args.type;
    switch ($scope.type) {
        case "orgs":
            $scope.RemoveRolesDetach('detachOrg', $scope.selecteditemslist);
            $scope.recipientsOrg.splice($scope.index, 1);
            $scope.displayOrgs.splice($scope.index, 1);
            $scope.recipientsOrgIdArr.splice($scope.index, 1);
            break;
        case "people":
            $scope.RemoveRolesDetach('detachUser', $scope.selecteditemslist);
            $scope.recipientsPeople.splice($scope.index, 1);
            $scope.displayPeople.splice($scope.index, 1);

            $scope.recipientsPeopleIdArr.splice($scope.index, 1);
            break;
    }

});
