Javascript angularjs如何通过下划线或其他方式从数组中删除对象

我的问题看起来与其他问题相似，但事实并非如此

请看一看，了解我的情况

我有一个对象数组，看起来像这样

$scope.events =[
    {
        $$hashKey: "009"
        _allDay:false
        _id:5
        allDay:false
        className:[]
        end:Date {Fri Aug 08 2015 12:30:00 GMT+0530 (IST)}
        start:Date {Fri Aug 08 2015 12:30:00 GMT+0530 (IST)}
        title:"Birthday Party"
    },
    {
        $$hashKey:"006"
        _id:2
        end:Date {Wed Aug 05 2015 00:00:00 GMT+0530 (IST)}
        start:Date {Sun Aug 02 2015 00:00:00 GMT+0530 (IST)}
        title:"Long Event"
    },
    {
        $$hashKey:"007"
        _id:3
        allDay:false
        id:999
        start:Date {Fri Aug 07 2015 13:00:00 GMT+0530 (IST)}
        title:"Angular Event"
    },
    {
        $$hashKey:"008"
        _id:4
        allDay:false
        id:999
        start:Date {Tue Aug 11 2015 16:00:00 GMT+0530 (IST)}
        title:"Repeating Event"
    },
    {
        $$hashKey:"00A"
        _id:6
        end:Date {Sat Aug 29 2015 00:00:00 GMT+0530 (IST)}
        start:Date {Fri Aug 28 2015 00:00:00 GMT+0530 (IST)}
        title:"Click for Google"
    }
]

var selectedObj = {
    $$hashKey:"009"
    _allDay:false
    _id:5
    allDay:false
    className:[]
    end:Date {Fri Aug 07 2015 12:30:00 GMT+0530 (IST)}
    start:Date {Fri Aug 07 2015 12:00:00 GMT+0530 (IST)}
    title:"Birthday Party"
}

现在我必须从这些数组中删除一个对象，如下所示

$scope.events =[
    {
        $$hashKey: "009"
        _allDay:false
        _id:5
        allDay:false
        className:[]
        end:Date {Fri Aug 08 2015 12:30:00 GMT+0530 (IST)}
        start:Date {Fri Aug 08 2015 12:30:00 GMT+0530 (IST)}
        title:"Birthday Party"
    },
    {
        $$hashKey:"006"
        _id:2
        end:Date {Wed Aug 05 2015 00:00:00 GMT+0530 (IST)}
        start:Date {Sun Aug 02 2015 00:00:00 GMT+0530 (IST)}
        title:"Long Event"
    },
    {
        $$hashKey:"007"
        _id:3
        allDay:false
        id:999
        start:Date {Fri Aug 07 2015 13:00:00 GMT+0530 (IST)}
        title:"Angular Event"
    },
    {
        $$hashKey:"008"
        _id:4
        allDay:false
        id:999
        start:Date {Tue Aug 11 2015 16:00:00 GMT+0530 (IST)}
        title:"Repeating Event"
    },
    {
        $$hashKey:"00A"
        _id:6
        end:Date {Sat Aug 29 2015 00:00:00 GMT+0530 (IST)}
        start:Date {Fri Aug 28 2015 00:00:00 GMT+0530 (IST)}
        title:"Click for Google"
    }
]

var selectedObj = {
    $$hashKey:"009"
    _allDay:false
    _id:5
    allDay:false
    className:[]
    end:Date {Fri Aug 07 2015 12:30:00 GMT+0530 (IST)}
    start:Date {Fri Aug 07 2015 12:00:00 GMT+0530 (IST)}
    title:"Birthday Party"
}

我在做什么

removedArray = _.reject($scope.events, function(event) {
   return event.$$hashKey == selectedObj.$$hashKey
});

$scope.events = removedArray;

$scope.events

未更新我已尝试

$apply

但未成功

有人能帮我找出我做错了什么吗

最佳做法是什么。这种肮脏的东西。

这应该可以让你使用标准的javascript（IE9+）：

使用下划线.js，您可以执行以下操作：

myArray = _(myArray).filter(function(obj) {
     return obj.$$hashKey!== selectedObj.$$hashKey;
});

您可能想使用函数，它基本上与dustmouse的答案相同，但我认为代码更可读

var selectedObj = {...}
$scope.events = [0,1,...,n];

$scope.events = _.remove($scope.events, function(element) {
  return element == selectedObj;
});

所选事件可以通过此过程删除。调用函数deleteEvent

  $scope.deleteEvent= function() {
        var index = $scope.events.indexOf(selectedObj);
        $scope.events.splice(index, 1);

  };
