使用代理时，jQuery不显示事件名称空间 [英] jQuery not showing event namespace when using proxy

问题描述

在我的脚本中，我希望具有两种类型的单击功能，具体取决于所单击的内容，并且我希望在单个功能中执行此操作.我决定使用名称空间来创建它，但是控制台给了我未定义的内容；

In my script I want to have two types of click functionality, depend on what is clicked and I want to do it in a single function. I decided to make it with namespaces, but the console gives me undefined;

这是代码:

$target1.on("click.Bst", $.proxy(self.selectNav, self));            

$target2.on("click.Bst.Type2", $.proxy(self.selectNav, self));

我的函数selectNav()在单击时执行，但是当我尝试获取event.namespace(事件作为s函数参数传递)时，我无法定义.

My function selectNav() executes on click, but when I try to get the event.namespace (event is passed as s function parameter) I get undefined.

selectNav: function(event){
 //other code runs  
 console.log(event.namespace);  //console log "undefined"
}

推荐答案

event.namespace仅在事件是通过.trigger(例如$target1.trigger('click.Bst'))而非本地DOM事件触发时定义的.与.proxy无关.

event.namespace is only defined when the event was triggered via .trigger (e.g. $target1.trigger('click.Bst')), not through native DOM events. It has nothing to do with .proxy.

我不得不承认，文档可能对此更加清晰.

I have to admit that the documentation could be clearer about this though.
