|
HTML pages uploaded to a course which contain dependencies either from iframes, |
|
javascript files or objects (FlashPlayerSwf, MediaSrc, XMPSrc, ConfigurationSrc, |
|
and PosterImageSrc) for which dependency is another file uploaded to the same |
|
course. |
|
|
|
Required input: |
|
href - dependency (either a relative URL, or an absolute URL) |
|
Optional inputs: |
|
docuri - URL of HTML page containing the dependency |
|
cdom - Course domain |
|
cnum - CourseID |
|
|
|
Output: |
|
returns an absolute URL constructed from the href provided, and the calling context. |
|
(this will be null, if the URL does not begin: /uploaded/$cdom/$cnum/docs/ or |
|
/uploaded/$cdom/$cnum/supplemental/). |
