Railsers:
Suppose I have a page inside an IFrame, and it knows nothing about
Prototype.js.
Now suppose I set the IFrames' src to javascript:void(function(){ ... }) and
put a big string of raw Javascript where that ... is.
Now suppose that string wants to ping a server with new Ajax.Request.
The JS source to foist prototype.js into an unwilling page reputedly looks
like this:
var newScript = document.createElement('script');
newScript.type = "text/javascript";
newScript.src = "/javascripts/prototype.js";
document.getElementsByTagName('head')[0].appendChild(newScript);
new Ajax.Request( '/ctrl/action', ...);
That looks beautiful (for various definitions of "beautiful"), however it
doesn't seem to affect the scope of the current JS.
My next experiment will foist first, with one src=javascript:void() line,
and will then evaluate the new Ajax.Request on a second
src=javascript:void() line.
I'm curious if there's a cleaner solution. (Note that project constraints
forbid me to simply <script src='...prototype.js'> in the target IFrame...)
