GetJavascriptInitFunctions question

[Paul Spencer <pspencer (at) dmsolutions.ca>]

Hi,

close but not quite.  Each set of functions has a separate purpose.   
OnLoad functions are inserted into the the onload function.  Init  
functions are added to a script tag at the end of the page.  The  
difference is that the init functions are executed while the page is  
being loaded and onload is executed after it is loaded.  This  
distinction probably isn't necessary with modern browsers but it was  
when we supported nn4.79 because there was no document.createElement

GetJavascriptFunctions returns functions that are to be put into the  
main javascript block ... these are available to be called by code in  
onload and init.

This whole thing should be cleaned up as the javascript architecture  
is really an ancient hack to make chameleon work in browsers like  
nn4.79 ... and since that's not really a requirement any more, it  
could be changed substantially to simplify.  Unfortunately, that's  
not a simple job so its not likely to happen soon :(

Cheers

Paul
