I am writing one of my own JQuery plugin. And I got some strange which make me confused.
I am using JQuery UI datepicker with my plugin.

usage:
$('.openMW').click(function(event){

HTML code:
<div id="taskBarAndStartMenu">
<div class="taskBarAndStartMenuM">
<a href="" class="openMW" >??IGTO</a>
</div>
<div class="taskBarAndStartMenuO"></div>
</div>
In my work flow:
when I click the "whatchHistory" button, my plugin would load a panel with JQuery UI datepicker applied which days had been set to be availabled or not.
I am using the function "getDays()" to get the available days list and stored the data inside daysWithRecords, and final the UI datepicker's function "beforeShowDay()" called the function "checkAvailability()" to set the days.
the variable "daysWithRecords" was declared inside Igtomw = function(elem , options) and was initialized inside the function getDays()
I am using the function "initialWatchHistory()" to initialization and render the JQuery UI datepicker in the web.
My problem is the function "checkAvailability()" cannot see the variable "daysWithRecords".The firebug prompts me that "daysWithRecords" is "undefined".
this is the first time I write my first plugin. So ....
Thank you very much for any help!!
