为什么event.keyCode不能在ng-keyup中工作？

这适用于onkeyup但不是ng-keyup ..我错过任何东西

Answer 1

使用Kernel.Bind<INoMultiBindingList<ITextExportService>>().ToMethod(ctx => { var services = new NoMultiBindingList<ITextExportService>(); foreach (var device in GetDevicesByEnvironment()) { var service = ctx.Kernel.Get<ITextExportService>(new ConstructorArgument("hotFolder", ctx.Kernel.Get<IHotFolderManager>( new ConstructorArgument("baseFolderPath", device.Path), new ConstructorArgument("defaultFileSearchPattern", "*.jmf")))); services.Add(service); } return services; }); 代替$event：

event

Angular在模板中公开jQuery ng-keyup="if ($event.keyCode == 13) setCurrent(pagination.navigatevalue);" 对象，请参阅doc

Answer 2

Event object is available as $event in ng event directives expressions. Another problem with your code is that you can't use control statements，例如if-else。简单的解决方案是使用逻辑AND operator &&。

您的代码如下所示：

ng-keyup="$event.keyCode == 13 && setCurrent(pagination.navigatevalue)"
