emberjs 动作 event.target 未定义 [英] emberjs action event.target is undefined
问题描述
这是一个 jsfiddle 的链接:http://jsfiddle.net/Qt972/
Here's a link to a jsfiddle: http://jsfiddle.net/Qt972/
当你运行 fiddle 时,你会看到一个名字和一个按钮,让人"打招呼.这工作正常,但是事件"未定义.
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.
一个更简单的案例也失败了:
An even simpeler case also fails:
有谁知道我该如何解决这个问题?

推荐答案
当您在操作回调中执行 console.log(arguments)
时,您可以看到实际上传递了 3 个参数.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.
您可以像这样重写您的编辑操作:
You can rewrite your edit action like this:
edit: function(view, event, context) {
var target = event.target;
...
}

UPDATE:自提交 657a2664 - 在 版本中可用0.9.6
我猜 - 只传递了一个 event
参数,它具有视图和上下文作为属性.因此,如果您想访问那些,您必须执行以下操作:
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;
...
}
