Javascript and bookmark names

Matt__W — Thu, 16 Jun 2016 14:51:24 GMT

Got another one for you @elliott.rosenfeld. 🙂

I have a model with three bookmarks in it. When I run the code below.....

var doc = app.ActiveDocument();

var varBM = doc.Bookmarks;
for (x in varBM) {
   print (varBM[x]);
}

...it returns this at the debug window.

adsk::js::Bookmark(name = "")
adsk::js::Bookmark(name = "")
adsk::js::Bookmark(name = "")
Script evaluation: 0.002 seconds

Which says to me it's not recognizing the names of the bookmarks and returning an empty value? And what's the deal with "adsk::js::"? Is IW / JS just being polite with its error messages?!?

*heads off to scour the IW JS documentation and inner-webs for clues*

Hey Matt,

Haven't forgotten about you. I've been trying to puzzle this one out, and I am thinking that the issue here may be because the Bookmark metadata is stored in JSON inside a model's unver folder. Just for reference, here's what I am thinking may work:

Step 1)

// Set a variable for your Bookmarks folder, defining where the bookmarks are stored for your model

var bmFolder = "C:/Users/yourusername/Documents/Autodesk InfraWorks Models/Autodesk 360/modelid#/modelname.files/unver/Bookmarks";

Step 2)

//Retrieve the active model and document

var model = app.ActiveModel;

var doc = app.ActiveDocument();

Step 3)

//Process each file in bmFolder (still not 100% certain the syntax for this)..

Step 4)

//parse the JSON strings within your bmFolder

Step 5)

//print

Thanks,

Elliott

So I wasn't losing my mind thinking that the Bookmarks function isn't fully functional? Glad to see it wasn't something I was doing wrong.

I'll hack away at this tomorrow and see what I can scratch together.

So I've got this together but I'm getting stuck on iterating through the Bookmarks folder to search for JSON files. I can't seem to tap into the Script.FileSystemObject (which would make this infinitely easier) so now I'm at a loss. Nothing I've tried has worked so far. Below is my code. Any thoughts? Can anyone at the factory put me in the right direction?? This is my first real attempt at Javascript so I'm on a mission to figure this out and learn from it. You could say it's gotten personal now. 🙂

// Some global vars...
var curModel = app.ActiveModel;
var db = curModel.Db;
var fPath = db.FilesPath;
var bMarks = fPath + "unver/Bookmarks"
print (bMarks);

if(!file.FolderExists(bMarks)) {
      alert("Folder doesn't exist");
   }
   else {
//      alert("Folder exists"); // The folder still exists even if all bookmarks have been deleted
      print ("");
      print ("========================================");
      print ("Loop through directory and get all files");
      print ("========================================");
      print ("");

// Code that I found online that I attempted to make work but...
      var fileList = getFiles(bMarks);  <<--- THIS IS WHERE IT DIES.
      for (var i = 0; i < fileList.length; i++) {
         if (fileList[i] instanceof File) {
            print (fileList[i]);
         }
   }
}

Hey Matt,

So a colleague helped me out with this one.

Looks like your original line of thinking was actually pretty close. Try this out, it seems to work pretty nicely:

var bmList = app.ActiveDocument().Bookmarks;
for(var i=0; i<bmList.length; i++) {
    var bm = bmList[i];
    print((i+1) + ": '" + bm.name + "'");
}

Best,

Elliott

Hah great, back atcha. Although I can't take full credit, had to use my lifeline to answer this one.

Re: Javascript and bookmark names

Matt__W — Fri, 24 Jun 2016 18:59:38 GMT

One more hopefully quick question....

When I use the following code, Infraworks just blows through it and only sets the last bookmark as current. It's as if Infraworks isn't updating the view.

I've tried the Regenerate function, ProcessEvents, Update and UpdateFeature (both of which I don't think apply since I'm not writing anything to a database).

How do I get it to stop and open each bookmark and set it current??

var doc = app.ActiveDocument();

var bmList = app.ActiveDocument().Bookmarks;
for(var i=0; i<bmList.length; i++) {
    var bm = bmList[i];
    print((i+1) + ": '" + bm.name + "'");
    doc.MoveToBookmark(bm.name);
}

Sorry for the barrage of questions but I'm a newb when it comes to JS coding and I REALLY want to learn this and figure it out (with some help when needed).

Re: Javascript and bookmark names

Matt__W — Fri, 24 Jun 2016 19:44:53 GMT

Okay @elliott.rosenfeld.... So I found that if I use a WAIT function, I can get IW to actually show the bookmarks. But I don't have that warm and fuzzy feeling that that's the "correct" way to go about it. Comments? Suggestions? Care to use another life line? 🙂

var doc = app.ActiveDocument();

function wait(ms){
   var start = new Date().getTime();
   var end = start;
   while(end < start + ms) {
     end = new Date().getTime();
  }
}

var bmList = app.ActiveDocument().Bookmarks;
for(var i=0; i<bmList.length; i++) {
    var bm = bmList[i];
    print((i+1) + ": '" + bm.name + "'");
    doc.MoveToBookmark(bm.name);
    wait(1000); // wait 1 second before continuing
}

Hey Matt,

Sorry for the late response, i've been at a conference. The WAIT function does seem to function (pun intended), but you are right that there may be a better way. Nice work getting that to work, and sure I'll ask some colleagues about any possible improvements!

Best,

Elliott

Thanks. I appreciate your help (and patience) on this. 🙂

Re: Javascript and bookmark names

Matt__W — Thu, 30 Jun 2016 14:28:33 GMT

@elliott.rosenfeld any progress on this? I feel like I've been WAITing forever! (wakka wakka wakka) I have to believe there's a more correct way to do this because if the wait period isn't long enough, Infraworks could still be processing while the JS continues to run which would mess things up. Processor speed and model size both play a factor in this so I hope there's a function that will handle this, otherwise I may need to bump up the wait time to allow Infraworks to catch up, so to speak.

Re: Javascript and bookmark names

Matt__W — Mon, 18 Jul 2016 17:44:16 GMT

*BUMP!*

@elliott.rosenfeld, any chance you've had the opportunity to discuss the wait issue with anyone?? (I just got back from a 2-week vacation which is why I didn't bother you about this earlier. )

Re: Javascript and bookmark names

elliott.rosenfeld — Mon, 18 Jul 2016 17:50:04 GMT

Hey Matt,

Great timing, I just heard back from some colleagues today.

(and sorry for the delay! We had a company week of rest, then I actually had some extra time away from the forum to move, as I have just switched office locations.)

Here's what I was told after I forwarded this thread and your question to some colleagues: "While we are not aware of a function that asks AIW if it is ready, you may want to try to replace the WAIT function with app.Sleep(1) instead."

Let me know how this works out for you! If that doesn't provide the solution you're looking for, we can continue to dive into this and find a better way.

Best,

Elliott

Re: Javascript and bookmark names

Matt__W — Mon, 18 Jul 2016 18:23:54 GMT

So no built in way of determining if a command has finished? Such as setting a bookmark current... *shrugs* Okay. I'll go with the sleep function since it's a built-in function and not something home-grown.

Thanks for all of your help, @elliott.rosenfeld!!

Re: Javascript and bookmark names

Matt__W — Mon, 18 Jul 2016 19:40:09 GMT

Soooo... after a little more in-depth testing with a few other models it appears I *don't* need a sleep or wait function after all to achieve what I'm doing.

Stay tuned for an AKN article about batch printing snapshots using JS.

Thanks again for putting up with me and my questions @elliott.rosenfeld.
