Traversing to the last child element in a tree using jQuery selector

<div id="myDIV">
 <div>
  <span>
    <a href="#">Seek me!</a>
  </span>
 </div>
</div>

How can I find A tag using jQuery selector (not looping through children()) If I know only myDIV id.

Well, it really sounds a bit awkward. For example I've clicked #myDIV and i need to get text f开发者_如何转开发rom the last child tag. It could A, span, div, p, whatever. Also myDIV could not even have any children elements.

Excuse me my English

Like this:

$("#myDIV :not(:has(*))")

This will find all the last "leaf" elements, you could restrict to only <a>, etc if you wanted. For your markup:

$("#myDIV :not(:has(*))").text() // "Seek me!"
$("#myDIV :not(:has(*))").length // 1

:empty doesn't work here (because it has a text node child), but finding things with no child elements will, here's an example page showing this.

It's just $('#myLink')
