I think I get the point. Even though I'm not able to understand this
script now or how to tweak it, I understand that this option blocks the
loading process of the annotation feature. It is "cheaper" to do that as
it stops a process not required for a given type of users.
But, please, one more question. When is this script executed? Each time
a document is loaded or even reloaded?
The JavaScript code of this extension is evaluated (loaded into
browser's memory) for each wiki page, and the code at the end of the
second JSX object is executed after a wiki page finished loading (in the
browser):
document.observe('xwiki:dom:loaded', function() {
... // code executed after the page finished loading.
});
Does this match your needs:
document.observe('xwiki:dom:loaded', function() {
// if the action on the current document is not view, don't load
annotations
if (XWiki.contextaction != "view" || !XWiki.hasEdit) {
return;
}
...// the rest of the code that loads the annotation feature.
});
And this is the reason why I'm not forced to
include xwikivars.vm in the
modified JSX. Please, am I right? I could use !$hasEdit, but then I must
include #template('xwikivars.vm'). I've tried and it seems to work fine.
Exactly.
Please, why don't directly use
!$xwiki.hasAccessLevel('edit')?
To avoid (re)evaluating/recomputing the edit right multiple times (it
may be costly). The value returned by $xwiki.hasAccessLevel('edit') is
cached in $hasEdit to speed up the page loading time. $hasEdit
(velocity, server-side) is also send to the client side in the value of
the "hasEdit" property of XWiki JavaScript object.
Hope this helps,
Marius
