Re: Javascript?

javascript can use libs just like serverside javascript does, and you can include new javascript objects. You can create some objects and classes just like java.(even in html you can do that by including .js files defining classes using the <SCRIPT SRC="xxx.js"></SCRIPT> syntax)

Concerning dcop or otherthing access, it would be done the same way you access activeX objects or java applet. The extention extends the local DOM with objects and functions.

let suppose we want to load a new document called "foo.doc" in kword

then a document.open("foo.doc") would do the job.
you could also let the user choose the document with the following line:
document.menu.file.open.select();
or you could rename that menu:
document.menu.open.rename("Open a File");

Now let say you want to include a picture:
oMyPic=document.createElement("IMG")
oMyPic.src="foo.png";
document.appendChild(oMyPic);

Now, more complex thing: you want to include a speadsheet:
oMyEmbedSpreadSheet=document.createElement("EMBED");
oMyEmbedSpreadSheet.src="foo.xls";
document.appendChild(oMyEmbedSpreadSheet);

Now you want to create an empty embeded kspread object:
oMyEmptySheet=new Kspread("Sheet1","Sheet2");
oMyEmbedEmptySheet=document.createElement("EMBED");
oMyEmbedSpreadSheet.nodeValue=oMyEmptySheet;
document.appendChild(oMyEmbedEmptySheet);

Now you want to set the background of the 1st cell of the first sheet to red:
oMyEmptySheet.sheet[0].cells[0][0].style.background="red";

As you see, oMySpreadSheet would just behave as a standard html object with datas and methods.
And by that way, exporting thoses pages to the net with scripting would be possible.

Javascript also include security concepts.

that was just my 2 cents.

PS: don't try to think in terms of netscrape 4.x javascript, its DOM is so poor that of cours almost nothing complex is possible and most of its usage is reserved to string computation and document.write().
