[jQuery] Is there a jQuery way to sort span-elements?

[Audrey Lee]

Hello,

Assume I have 3 span-elements:

<div id="names">
  <span id="s1">Fred</span>
  <span id="s2">Alan</span>
  <span id="s3">Sally</span>
</div>

Is there a jQuery way to sort them so I get this:

<div id="names">
  <span id="s2">Alan</span>
  <span id="s1">Fred</span>
  <span id="s3">Sally</span>
</div>

??
