---+++ Repositioning HTML for CSS and javascript links
|
|
|
|
Modern HTML commonly uses CSS and Javascript. This requires <link>
|
|
elements in the HTML <head> element or <script> elements in the <body>.
|
|
Unfortunately this seriously harms re-using HTML DCG rules as components
|
|
as each of these components may rely on their own style sheets or
|
|
JavaScript code. We added a `mailing' system to reposition and collect
|
|
fragments of HTML. This is implemented by html_post//2, html_receive//1
|
|
and html_receive//2.
|
|
|
|
* [[html_post//2]]
|
|
* [[html_receive//1]]
|
|
* [[html_receive//2]]
|
|
|
|
The library predefines the receiver channel =head= at the end of the
|
|
=head= element for all pages that write the html =head= through this
|
|
library. The following code can be used anywhere inside an HTML
|
|
generating rule to demand a javascript in the header:
|
|
|
|
==
|
|
js_script(URL) -->
|
|
html_post(head, script([ src(URL),
|
|
type('text/javascript')
|
|
], [])).
|
|
==
|
|
|
|
This mechanism is also exploited to add XML namespace (=xmlns=)
|
|
declarations to the (outer) =html= element using xhml_ns//2:
|
|
|
|
* [[xhtml_ns//2]]
|
