OK.when you create a function in javascript with parameters then the
function will look like function(var1, var2){}, you can use those variables
by their name directly there is no need to use the $wnd with the variable
name unless the variable is defined as global/outside the method scope {}
Now in your case if canvasname is passed as param to the function then you
wont have to use $wnd in order to access it. but in case you need to store
its value in order to use it somewhere else then you will need to create a
global variable per page scope;
therefore you will need to include it in your header tag
<script>var canvasnameval ;</script> then inside your call back method you
will do $wnd.canvasnameval = canvasname;
Hope that this help.
