Just shooting spitballs here... is there no way to load the js in
the html and use that in the x3d script node ?<br>

X3DOM is different because it runs directly in the browser
environment. I was discussing the issue strictly from the standpoint
of X3D. There may be an X3D environment that does not run in the
context of a browser (e.g., Xj3D). The browser capabilities cannot
be assumed for this type of environment.<br>

Thanks for replying and contributing to the discussion. I
hope I am following your comments correctly.<br>
<br>
In X3D (not necessarily X3DOM), a Script node defines a new
name space. The only way to communication between functions
in different Script nodes is to pass events OR directly
access the other node's events (directAccess='TRUE'). If you
were to read in a Script node in an external X3D file (e.g.,
via GetX3dFromURL), then that Script node would be in a
separate namespace as above.<br>
<br>
Don's comment relates a desire to import JavaScript
(formally ECMAScript) into an existing Script node so that
functions and data in the imported file could be accessed
directly via ECMAScript's standard mechanisms (call, data
access, etc.). This is a really important feature for
ECMAScript libraries. <br>
<br>
There was a previous comment that is a feature that allows
this to happen using 'required'. I cannot find that feature
in the ECMAScript Language Specification at <a
moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://www.ecma-international.org/ecma-262/5.1/">http://www.ecma-international.org/ecma-262/5.1/</a>
If it is not in the ECMAScript specification, then it is not
supported in the X3D Script node. The X3D specification
development team did not consider the impact of such a
feature. If it is in the specification, then a review of the
specification needs to performed to make sure everything
operates as intended.<br>
<br>
Also the AJAX functions XHR* and XHttp* are not in the
ECMAScript specification so that it would not be possible to
access the external file and 'eval' it.<br>

No method currently exists to import source
for an external Javascript<br>
library into an embedded X3D Script node.<br>
<br>
The ECMAScript specification reserves
keywords "import export" but does not<br>
define functionality.<br>

X3D needs a similar mechanism where an X3D
Script author can use/reuse an<br>
external Javascript library.<br>
