我在文档上使用jquery keydown事件获取了（TypeError jQuery），它引发了很多事件，而不仅仅是选定的事件

Question

I'm using a plugin called Vex which is used for dialogs.

Vex works by creating dialogs on the fly using JS so the html doesn't exists on the page so for that reason, I used the following code. The problem with this is that cause the keydown event is fired on the document, it's causing all keydown events to fire even though I have put the selector in '.test1'

$(document).keydown('.test1', function(e) {
    //do stuff here
});

Please see the fiddle example here (see the errors logged in the console)

Any ideas how to stop this?

Answer 1

Try using .on() if you want to bind dynamic content .

$(document).on("keydown", ".test1", function(e){
    //do stuff here
});
