ExtJS 4.1.1.a - TreePanel上的键盘导航问题(ExtJS 4.1.1.a - Keyboard navigation issue at TreePanel)

我正面临着TreePanel的键盘导航问题。 这是我的treepanel配置:

rootVisible: false,
animate: true,
autoScroll: true,
useArrows: true,
border: true,
singleExpand: true,

最后我将树作为单个窗口项; 然后展示它。

我不能使用键盘箭头来展开/折叠项目。 我只能使用向上/向下箭头来上下移动。

这是一个错误还是我错过了什么?

任何帮助将受到很多赞赏。


I'm facing keyboard navigation problem with TreePanel. Here's my treepanel configuration:

rootVisible: false,
animate: true,
autoScroll: true,
useArrows: true,
border: true,
singleExpand: true,

Finally I put the tree as a single item of window; then show it.

I can't use keyboard arrows to expand/collapse items. I can only use up/down arrows to go up & down.

Is this a bug or am I missing something?

Any helps will be appreciated a lot.

最满意答案

是的,如果您已指定传输安全性,则将使用SSL。 我建议两种可能性:

  1. 您已将Fiddler配置为查看SSL安全连接(这是可行的,但在大多数情况下不建议这样做)。
  2. 您没有引用您认为引用的绑定。

Yes, if you've specified transport security, SSL will be used. I'd suggest 2 possibilities:

  1. You've configured Fiddler to view SSL-secured connections (this is possible but not recommended in most cases).
  2. You're not referencing the binding that you think you're referencing.
