Static variables should be typically accessed through the full namespace
(i.e., myAppNamespace.myClass.myStaticVar): «Accessing those class members
involves the fully-qualified class name» [1].
Note: if you have lots of access to a static variable (for example, in a
'for' loop), this may become slow in Internet Explorer 6 [2]. So, in that
circumstance, I recommend creating a cache variable in that code region:
var classRef = myAppNamespace.myClass;
for(var i = 0; i < 1000; i++){
// do something with classRef.myStaticVar
}
Although only recommended for this sort of case, I'd also like to have some
feedback on this specific tweak: this is not, AFAIK, part of any advised
practice (at least, up until now). If this is interesting, it may be put in
qooxdoo class documentation.
