is it possible to add to an element type or maybe a css selection an own event function?
是否可以添加元素类型或css选择自己的事件函数?
something like:
$("a").bind("blub", function() { alert("aaa" + this); });
$("a").get(0).blub();
i want define some functions which are only available for some special elements eg.:
我想定义一些仅适用于某些特殊元素的函数,例如:
the <div class="myDivContainer">...</div> should have the function available:
$("myDivContainer").get(0).blub();
but on maybe:
但也许:
$("myDivSeparator").get(0).blub();
this should not work, because it was not defined for it
这应该不起作用,因为它没有为它定义
is this possible?!
这可能吗?!

You can create custom events with bind and trigger. See for example this question.
您可以使用bind和trigger创建自定义事件。例如,请参阅此问题。
You must use the trigger method to call the custom event:
您必须使用触发器方法来调用自定义事件:
$("a").bind("blub", function() {});
$("a").trigger("blub");
Of course you can trigger the "blub" event only for elements that bind has been called before.
当然,您只能为之前调用过绑定的元素触发“blub”事件。
If you want to use blub as a method, then you need to modify/extend the jQuery itself.
如果你想使用blub作为方法,那么你需要修改/扩展jQuery本身。
