javascript - AngularJS - ngClick 上未调用 Controller 方法 - 无错误

Question

如果单击按钮，我会尝试调用方法removePlayer(playerId)。但是，该方法不会被调用，或者至少它内部的语句不会触发，因为我在顶部放置了一个 console.log() 语句。

控制台是空的，所以我真的一无所知。这是我的代码:

Controller :

function appController($scope) {
    $scope.players = [];
    var playercount = 0;

    $scope.addPlayer = function(playername) {

        $scope.players.push({name: playername, score: 0, id: playercount});
        playercount++;
    }

    function getIndexOfPlayerWithId(playerId) {
        for (var i = $scope.players.length - 1; i > -1; i--) {
            if ($scope.players[i].id == playerId)
                return i;
        }
    }

    $scope.removePlayer = function(playerId) {
        console.log("remove");
        var index = getIndexOfPlayerWithId(playerId);
        $scope.players.slice(index, 1);
    }
}
appController.$inject = ['$scope'];

HTML:

...
<table id="players">
        <tr ng-repeat="player in players">
            <td>{{player.name}}</td>
            <td>{{player.score}}</td>
            <td><button ng-click="removePlayer({{player.id}})">Remove</button></td>
        </tr>
    </table>
...

您不应在 ng-click 表达式中使用大括号 ( {{ }} )。你应该写:

<button ng-click="removePlayer(player.id)">Remove</button>
