Change the way scriptaculous loads it''s libraries

Dear all

Undoubtly you have heared about the GWT framework, which is being used
more and more around. One of its virtues is that it focuses on clean
design and strict programming rules. An interesting extension has been
written as part of the GWT widget library [1] which allows GWT to
integrate the scriptaculous effects. However there seems to be a
problem with the way scriptaculous loads other libraries, in this case
effects.js.

It uses the document.write() technique which breaks apparently with a
clean DOM convention, please see the related thread [2]. Currently we
can use scriptaculous in a ''save'' way by patching it. Since
scriptaculous is so an important part in GWT now, could it maybe be
developed also with GWT integration in mind?

Many thanks
George

Re: Change the way scriptaculous loads it''s libraries

document.write() is required for the loading technique to work on  
Safari (i think 2.0 up to 2.0.3 or something,
because of a Safari bug that apparently got fixed).

Note that _scriptaculous.js is not required_ for the other libs to  
work, so can just include (for example)
effects.js and dragdrop.js so that drag-and-drop works. effects.js is  
required for all other libs, btw.

Maybe it''s easier in this case to use the loading techniques included  
with GWT? (no idea how they work,
never used it).

Re: Change the way scriptaculous loads it''s libraries

Thomas:

I tried this bit of code in scriptaculous.js and it seems to be working
fine with Safari 2.0.4 so aparently whatever it was with previous
Safari, it was fixed in 2.0.4.  Overall, the DOM implementation is
better than document.write().  So probably in the future,
scriptaculous.js can switch to DOM implemtation for JS injection when
the majority of the Safari users are upgarded to 2.0.4 or higher :).

if(scriptElem)
    {
        var script = document.createElement("script");
        script.type="text/javascript";
        script.src=libraryName;
      //  alert("loading "+libraryName);
        scriptElem.parentNode.insertBefore(script,
scriptElem.nextSibling);
    }
    else
    {
      document.write(''<script type="text/javascript"
src="''+libraryName+''"></script>'');
