问题描述

我需要检查div的内容是否为 或更多的<div>等.

I need to check whether the contents of a div are either   or more <div>'s and such.

我想也许我可以这样做，例如$('#right-rail').content或$('#right-rail').value甚至$('#right-rail').children()，但这似乎不起作用.

I thought maybe I could do this like $('#right-rail').content or $('#right-rail').value or even $('#right-rail').children(), but it doesn't seem to work.

我得到的只是未定义"或"[对象对象]".

All I get is either "undefined" or "[object Object]".

感谢我可以获得的帮助:).

Thanks for any help I can get :).

PS，如果您现在还没有猜到的话，请使用jQuery.

PS, using jQuery if you hadn't guessed by now.
