clearing up the browser memory problems (although Jordi already mentioned it
I think)
if you have javascript objects/variables referencing DOM elements (html
divs, images, mouseevents etc) you need to make sure those are deleted
(de-attached from the html elements) or the html elements will keep on
existing in memory for the rest of your browser session.
so every DynLayer has a reference to atleast an HTMLDIVElement.. that has to
be removed by setting the variables/objects to null
so:
DynLayer.elm=null
would remove the link between the DynLayer.elm object and the actual
HTMLDivElement, making the DIVElement get removed from memory as well.
Note that it might stay in memory even after a refresh, but I think that's
because IE only does memory-freeing at a certain interval, so it will be
gone in your next refresh or after a few minutes/seconds (my perception of
it)
...to much freetime today
