I would like to see a (written) best practice of
putting all javascript content into the head of the
XHTML document.
Reason 1:
Moving all script into the head makes it easier to find and makes impossible bad (and
often non WCAG
compliant) practices such as attaching script to xml attributes.
It makes it less of a jungle.
Reason 2:
If we have no script in the body of any documents then users can implement filters which
remove any
script after the</head> tag. This would make script injection certifiably
impossible.
WDYT?
Even if it's not possible to enforce it everywhere, I still think that
it should be a written best practice which should be followed as often
as possible. It's good for the quality of the code, it's less messy, it
makes it easier to find places where javascript is written.
As for code depending on existing content, a practice which works in
most cases is to use certain classes which are used in an
xwiki:dom:loaded script. Even something as complex as the WYSIWYG
initialization might be done with an XML comment or a processing
instruction, which can be parsed (JSON).
<?xwiki-wysiwyg
{
hookId: 'abc',
cacheId: 'xyz',
plugins: ['font', 'color', 'table']
}
?>
