I've run into a problem using the Automating Bookmark tutorial's script, which I'll post here:
 
function FindBookmarkByName(oBkMkParent,cFindName,nInc)
{
if(nInc == null)
nInc = [1];
else if(typeof(nInc) == "number")
nInc = [nInc];
 
var aBkMks = oBkMkParent.children;
var oRtn = null;
if(aBkMks != null)
{
for(var i=0;i

var aSchedNames = [ "....Choices in here...."];
 
var cRtn = app.popUpMenu.apply(app, aSchedNames);
if(cRtn != null)
{
app.execMenuItem("NewBookmark");
app.execMenuItem("NewBookmark");
 
var oBkMk = FindBookmarkByName(this.bookmarkRoot,"Untitled");
if(oBkMk != null)
oBkMk.name = cRtn;
 
var oBkMkEx = FindBookmarkByName(this.bookmarkRoot,"Untitled");
if(oBkMkEx != null)
oBkMkEx.remove();
}
 
The problem is that this runs successful only for a few bookmarks, then the bookmarks begin to be named Untitled. If I double click on Untitled then the name will change but that's an extra step that obviously was not part of the design. Any suggestions?

..Hmm...I'm having trouble seeing the whole function on my post so here's the link if you can't see it:

Any reason why you're creating new bookmarks using app.execMenuItem("NewBookmark") instead of the createChild() method?

Quote from Tutorial:

"The most obvious method is the bookmark.createChild() function. This function creates a new bookmark underneath an existing bookmark. All PDF documents, even ones with no bookmarks at all, have an invisible top-level bookmark called doc.bookmarkRoot. So we don’t need to worry about creating the first bookmark in the PDF, bookmark.createChild() works for creating any bookmark we might need. This function is easy to use and creates the bookmark in exactly the position it needs to be in. The downside to using this function is that it can only create bookmarks that execute JavaScript. None of the other bookmark actions can be set from an automation script. This works fine if we want our new bookmark to run a script, but it doesn’t help for making position-independent, page-navigation bookmarks."

If you think there is a better way, please share :) As I wrote, the tutorial's method seems flawed for multiple uses.

I don't understand. If the tutorial (which one, by the way?) recommends using createChild(), as I did, why did you use the menu item?

I posted the url to the tutorial in my 2nd post. Here it is again: http://acrobatusers.com/tutorials/2008/10/auto_bookmark_creation . It does not recommend createChild because it doesn't help for position-independent page-navigation. It does not contain the js Go to page, or so it says or if I'm mistaken. If you do have an alternative solution using createChild please share.

Edit: I've been looking around and haven't been able to find a function using createChild() that allows for the destination to be set based on current page selection (that's why I use the New Bookmark menu item).

You can use the cExpr parameter of createChild to set the action of the new bookmark you've created to whatever JS code you want. For example, this code will create 3 bookmarks that go to pages 1 to 3:
  1. this.bookmarkRoot.createChild({cName:"Page 1", cExpr:"this.pageNum = 0", nIndex: 0})
  2. this.bookmarkRoot.createChild({cName:"Page 2", cExpr:"this.pageNum = 1", nIndex: 1})
  3. this.bookmarkRoot.createChild({cName:"Page 3", cExpr:"this.pageNum = 2", nIndex: 2})

Okay, this will work; however, I need the bookmark to point to the page that is selected when the action is run. How would I go about changing the cExpr to accomplish this?

If my explanation was confusing, here is a breakdown:
1)user selects option (coding already done)
2)page that is currently being viewed is bookmarked with destination of said page


Edit: Current Code fyi:
this.bookmarkRoot.createChild({cName:cRtn, cExpr:"this.pageNum=???", nIndex: this.numPages-1})

(cRtn is a variable previously defined)

cExpr: "this.pageNum=" + this.pageNum
