AngularFire - 删除单个项目 [英] AngularFire - Remove Single Item

问题描述

这是我认为的相关代码:

Here is the relevant code in my view:

p(ng-repeat="t in todos")
input(
    type="checkbox",
    ng-model="t.done",
    ng-click="clearItem($event)"
    )
{{t.text}} done? {{t.done}}

单击复选框时，我希望从数据库中删除 todos 数组中的相应对象.

When the checkbox is clicked, I want the appropriate object in the todos array to be removed from the database.

我的clearItem函数如下:

$scope.clearItem = function(event) {
        todoRef.remove($scope.t);
    }

但是，这会删除我数据库中的所有条目.我希望它只删除有问题的特定对象.无论如何我可以这样做吗?

However, this removes all the entries in my database. I want it to remove only the specific object in question. Is there anyway for me to do this?

推荐答案

好的，想通了.

当使用ng-repeat 循环时，在todos 中使用(id, t).这允许您将 id 作为参数发送到 ng-click 函数，而 $scope.todos.$remove(id) 仅起作用很好.

When looping using ng-repeat, use (id, t) in todos. This allows you to send id as the parameter to the ng-click function, and $scope.todos.$remove(id) works just fine.
