Sorting Alphanumeric Data By using orderBy
<p>Am trying to sort the <code>ng-options</code> data by using <code>orderBy</code> , My data contains both alphabets and string's .  i can able to solve this<code>["A10","B2","C1"]</code> kind of data's, My question here in how to sort this<code>["1","2","10","a","b","C"]</code> kind of data's ? Is it possible to do this ! . Searched in many sites but didn't get any ideas so someone help me or clarify me from this .
Here is my working code,</p>

<pre><code>ng-options="option.id as option.roomno for option in MyData 
   | unique:'roomno' | orderBy:'roomno' "
</code></pre>
