javascript - Reaching variables in jQuery -


i have code :

<script type="text/javascript">     var currentpicture;//default picture     var picel;//the image viewer element     jquery("#backimageshower").hover(         function(i)         {             picel = jquery("#dynloadarxdock > img");             currentpicture = picel.attr("src");             picel.attr("src","back.jpg");         },         function()         {             picel.attr("src",currentpicture);         }     ); </script>

but when run code, says picel not defined. think because of closures code runs :

<script type="text/javascript">     var currentpicture;//default picture     jquery("#backimageshower").hover(         function(i)         {             currentpicture = jquery("#dynloadarxdock > img").attr("src");             jquery("#dynloadarxdock > img").attr("src","back.jpg");         },         function()         {             jquery("#dynloadarxdock > img").attr("src",currentpicture);         }     ); </script>

but code includes global variable , works.

can tell me why?

thanks.

the problem you're mixing casing. variable declared picel used picel (lowercase 'l', error is).
