<body ng-app="myApp" ng-controller="tasksCtrl">
    <div>
        <table class="table table-striped">
            <tbody>
                <tr ng-repeat="task in tasks">
                    <td>
                        <a class="btn" data-toggle="modal" data-ng-click="removeRow(task)">Delete</a>
                    </td>
                </tr>
            </tbody>

    </div>

    <script>
        var app = angular.module('myApp', []);

        app.controller('tasksCtrl', function($scope, $http) {
            $http.get("data.json")
                //$http.get("/todo/api/v1.0/tasks")
                .success(function(response) {
                    console.log(response.tasks)
                    $scope.tasks = response.tasks;
                });

            $scope.removeRow = function(task) {
                $scope.tasks.splice(task, 1);
            };
        });
    </script>
</body>

Answer 1

Try like this 这样尝试

View 视图

<a class="btn" data-toggle="modal" data-ng-click="removeRow($index)">Delete</a>

Controller 控制者

$scope.removeRow = function(index) {
   $scope.tasks.splice(index, 1);
};

Answer 2

You need to get the index of trying to delete 您需要获取尝试删除的索引

to do that, 要做到这一点，

 $scope.removeRow = function(task) {
     // get the index
     var index = $scope.tasks.indexOf(task);

     //delete the element from the array
     $scope.tasks.splice(index, 1);
 };

PS : if you pass the $index through ng-click as data-ng-click="removeRow($index)" this will work only if there is no order by options in ng-repeat if you have sorting options then your deletion gets wrong. PS： 如果您通过ng-click将$index传递为data-ng-click="removeRow($index)"则只有在您有排序选项的情况下，如果ng-repeat的选项没有顺序，此选项才有效错误。 because when sorting is there $index is same as the (0,1,2,3) but array order may have changed (ex: 0-index element can lay in 1-index of sorted array so if you pass the $index then it will delete the 1st index of actual array) so $index not represent the actual array element. 因为在排序时$index与（0,1,2,3）相同，但是数组顺序可能已更改（例如：0-index元素可以位于已排序数组的1-index中，因此如果传递$ index，则它将删除实际数组的第一个索引），因此$ index不代表实际数组元素。

sorting options => orderBy 排序选项=> orderBy
