[Dynapi-Help] Another newbie ? re: setURL() in IE

[Sam D. <sa...@eb...>]

Hi, sorry to post a newbie question here, but I'm trying to
load an external HTML file into a dynlayer and am having a problem
that I don't think I saw addressed in the list archives available over
the Web. I have one simple layer into which I want to load a simple 
external file:

<SCRIPT LANGUAGE="JavaScript"><!--
DynAPI.setLibraryPath('Core/lib2.0/')

DynAPI.include('core.api.*')
DynAPI.include('core.ext.loadhtml.js')

DynAPI.onLoad=function() {
  testlayer = new DynLayer(null,100,100,143,16,"#ffffff")
  testlayer.setURL("ext.html")
  DynAPI.document.addChild(testlayer)
}
//--></SCRIPT>

This works great in Netscape 4.73, but doesn't work in IE 5.0. I think I 
tracked down the error, but I'm not sure what to do about it. In the
file
"core.ext.loadhtml.js" there is a property called
"DynAPI.setURL.current"
which appears to be initialized to null (last line of the file). This is 
causing an error here on line 18, I think:

15: DynLayer.prototype.onLoad=function(e) {
16:   var lyr
17:   if (is.ie) {
18:     lyr=document.all[DynLayer.prototype.setURL.current].lyrobj
19:     lyr.elm.innerHTML=e
20:   } else if (is.dom) {

I'm getting "document.all[...].lyrobj is not an object" which seems to
fit
with using a null object as a reference into the document.all[] array.
So
the "current" propery should be a layer id tag, but which one? Or am I
way
off on what's happening here?

Anyway, if anybody read this far and knows how to make this work in 
IE, I'd be immensely grateful for any help. If this is a known bug
that's
being worked on that's not up on SourceForge yet, or if I'm doing
something
stupid like not including the right files or something, sorry about the
dumb post, but I would still appreciate a heads up. Thanks!

PS The API is awesome, and tremendously useful! Thanks to the
development
team for all the hard work they've put into it.

Sam,

I have encountered this error, but it dissappeared as I continued development on my
widget.
I think the solution is to not use the setURL method until the layer has been added to the
DynAPI.document.
By swopping the last 2 lines of your code, all should be OK.

e.g

DynAPI.onLoad = function ( )
{
  testlayer = new DynLayer(null,100,100,143,16,"#ffffff");
  DynAPI.document.addChild(testlayer);
  testlayer.setURL("ext.html");
}

Good Look

Mark

Re: [Dynapi-Help] Another newbie ? re: setURL() in IE answered!

[Sam D. <sa...@eb...>]

Mark,

Thanks a ton! For anybody browsing the archives or anything, Mark's fix
worked. To repeat,
use setURL() -after- you've added the layer to the DynAPI.document
object. Thanks again!

Sam
