Question

我用ng-repeat构建按钮：

<button ng-repeat="alphabet in alpha" ng-click="checkAlpha()" value="{{alphabet}}">{{alphabet}}</button>

$scope.alpha = 'abcdefghijklmnopqrstuvwxyz';

问题是如何仅删除单击的按钮。我在按钮中使用了ng-hide，但随后所有按钮都消失了。最好的方法是什么？感谢

HTML：

 <div ng-controller='ctrl'>
    <button ng-repeat='alphabet in alpha ' ng-click="checkAlpha($index)" value="{{alphabet}}" id="{{$index}}">{{alphabet}}</button>
</div>

JS：（相似）的

angular.module("app", []).controller("ctrl", function ($scope) {
    //lets create array from a string.
    $scope.alpha = 'abcdefghijklmnopqrstuvwxyz'.split("");

    $scope.checkAlpha = function(index) {
        $scope.alpha.splice(index, 1);//remove
    }
});
