Re: [RE: [Dynapi-Help] html links inside loadpanel documents]

[Bill W. <bil...@us...>]

Perhaps, after the page loads, you could go and get the loadpanel's
document.links array, and the iterate through them all and add to them a
target window, namely the layer you want them to show up in.  I hope this
works, because I plan on doing something like that.

Re: [RE: [Dynapi-Help] html links inside loadpanel documents]

[Scott A. L. <sc...@sc...>]

You should be able to use an afterload event to trigger the iteration
through the layer's document. Assuming the document is not from another
domain, you could use this to rewrite all links.  The loadpanel and
loadHTML extension both already attach the calling layer as a property
to the link, as .lyrobj, so you could just extend this loop to rewrite
the link as well:

- assign the calling layer as a property of the link (in .lyrobj)
- preserve the original href somehow, like: links[i]._href =
links[i].href
- replace the existing href with a void return: links[i].href =
"javascript:void(0);"
- assign an onclick handler to the links: links[i].onclick =
LoadPanel.handleClick

Then all you have to do is write the handleClick:

LoadPanel.handleClick = function(){
  this.lyrobj.loadHTML(this._href)
}

I suppose you could also change other things in the link, like the
status bar message and whatnot.
This would probably work for pure navigation links, not for links that
already use the "javascript:" protocol.  That would cause some weird
problems.

[Dynapi-Help] Links is a loadPanel revisited

[Scott A. L. <sc...@sc...>]

My mistake: the current version of loadpanel doesn't seem to use the
.lyrobj idea.

No problem.  Here's a quick run at a link-rewriter function.  This only
works in Netscape 4.x -- I still can't get the loadpanel to work in IE5
(what's up with that?), so I couldn't test it in that browser. Anyway,
it seems to work fine in NS. If someone wants to modify it for IE,
please do.

Add these static methods to the loadpanel.js code:

LoadPanel.rewriteLinks=function(e){
  var lyr = e.getSource();
  var l = lyr.doc.links;
  for (i=0;i<l.length;i++){
    l[i].lyrobj=lyr
    l[i].orig_href = l[i].href;
    l[i].href ="javascript:void(0);";
    l[i].onclick=LoadPanel.handleClick;
    l[i].onmouseover=LoadPanel.handleMouseover;
  }
};
LoadPanel.handleMouseover = function(){
  status=this.orig_href;
  return true;
}
LoadPanel.handleClick = function(){
  this.lyrobj.setURL(this.orig_href)
}

To use it, add the following eventlistener to your loadpanel:

var el = new EventListener();
el.onload = LoadPanel.rewriteLinks;
lp.addEventListener(el);

When the panel is done loading, the rewrite will be invoked on this
panel, and point the links to load in the panel instead of the browser. 
The LoadPanel.handleMouseover will take care the the status bar, so you
won't be seeing "javascript:void" down there. Of course this approach
will also wipe out any pre-exisiting onclick events in the link, so it's
not meant to be used for everything.

The .lyrobj seems to point to the parent DynDocument, not the parent
DynLayer (the LoadPanel).

The LoadPanel works in IE5 for me. But I cannot access the loaded html's
document object. I get a "Not Implemented Yet" error. I might try and force
IE5 to use the IE4 method and see if I have any more success.

Thank's for that, I'll try it...

It is probably possible to check for an existing onClick and save it so it
gets executed? I don't know if doing this just for links is the ideal
solution. Form's for example will have the same problem.
