Reading List of ways HTML can download a resource, I remembered I had done such a list a long time ago for XHTML 1.1, but never published it. So I took the old list and brushed things off to adjust to HTML5.
I call passive, URLs that do not trigger download when the page is loaded and active, URLs that automatically trigger a download.
element passive active
- a href
- applet archive
- area href
- audio src
- base href
- blockquote cite
- body background
- button formaction
- command icon
- del cite
- embed src
- form action
- frame longdesc src
- html (xmlns) manifest
- iframe longdesc src
- img longdesc src
- input src
- ins cite
- link href
- object data
- q cite
- script src
- source src
- track src
- video poster, src
-
Table of elements and attributes taking URL as values
I wonder if there is a missing index in HTML5 specification by type of values an attribute can take.
