emberjs action event.target未定义 [英] emberjs action event.target is undefined

问题描述

以下是jsfiddle的链接： http://jsfiddle.net/Qt972/

Here's a link to a jsfiddle: http://jsfiddle.net/Qt972/

当你运行小提琴时，你会看到一个名字和一个按钮，让人打个招呼。这样做很好，但是事件是未定义的。

When you run the fiddle you'll see a name and a button to make the "person" say hello. This works fine, however the "event" is undefined.

甚至更简单的情况也会失败：

An even simpeler case also fails:

有谁知道如何解决这个问题问题？

Does anyone know how I can fix this issue?

推荐答案

当您执行 console.log（arguments）在你的动作回调中你可以看到实际上有3个参数传递。第一个是视图，第二个是事件，第三个是上下文。

When you do a console.log(arguments) inside your action callback you can see that there are actually 3 parameters passed. The first one is the view, the second is the event and the third is the context.

您可以重写这样的编辑操作：

You can rewrite your edit action like this:

edit: function(view, event, context) {
  var target = event.target;
  ...
}

更新：自提交 657a2664 - 可在发布 0.9.6 我猜 - 只传递一个事件参数，其视图和上下文作为属性。所以如果你想访问那些你必须做以下的事情：

UPDATE: since commit 657a2664 - available in release 0.9.6 I guess - only a single event parameter is passed which has the view and context as properties. So if you want to access those you have to do the following:

edit: function(event) {
  var view = event.view;
  var context = event.context;
  ...
}
