Question

我有一个指令：

angular.module("App").directive('myDirective', function () {
    return {
        restrict: "E",
        },            
        templateUrl: "MyDirective.html"
    }
});

模板：

<input Value = "Test" ng-class="{{ngclass}}"/>

HTML：

<my-Directive ng-class="{'ng-invalid': param === false }"/>

是否可以将ng-class条件传递给指令？

您可以使用scope option，例如：

＆＃13;

@Override
public void onTaskRemoved(Intent rootIntent){
    Intent restartServiceTask = new Intent(getApplicationContext(),this.getClass());
    restartServiceTask.setPackage(getPackageName());    
    PendingIntent restartPendingIntent = PendingIntent.getService(getApplicationContext(), 1,restartServiceTask, PendingIntent.FLAG_ONE_SHOT);
    AlarmManager myAlarmService = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
    myAlarmService.set(
            AlarmManager.ELAPSED_REALTIME,
            SystemClock.elapsedRealtime() + 1000,
            restartPendingIntent
    );

    super.onTaskRemoved(rootIntent);
}

我不确定你是否可以通过表达式传递范围变量......

angular.module("App").directive('myDirective', function () {
    return {
        restrict: "E",        
        templateUrl: "MyDirective.html",
        scope: { invalid: '=' }
    }
});

<my-Directive invalid="param === false"/>

<input Value="Test" ng-class="{'ng-invalid': invalid}"/>

在angular指令中传递ng-class条件
