How to apply hypertext marker to text with specific character tag

I am trying to apply a gotolink marker in my text to a word that has a specific character tag. A couple of months ago, frameexpert helped me with some code that applies the newlink marker to text in a specific paragraph format, and I thought I could just modify it (see below). But I'm obviously missing something because it just won't work. The marker needs to be added to the specific words, so that they are a link, rather than to the beginning of the paragraph, so I know I need to do something about the offset location. But first, I just need it to work. Any help would be much appreciated! Thanks in advance.

The newlink marker part is easy :-). The gotolink portion is trickier because you have to get a TextRange of the text you want to apply the format to (after you add the gotolink marker to the text). I am jammed right now so I can't help too much.

Along with what Rick said, this is too much code for me to analyze. Plus, I am not completely sure what you want to do. Do you want to insert a marker, then apply a character format, or are you trying to find an existing character format and put the marker within it?

Without really analyzing the code, I did notice this:

        if (findLink.ObjectValid (doc) === true) {

ObjectValid() does not take any arguments. It looks like you might be trying to use it as a "find" mechanism, which is not correct. If you want to invoke a search, you have to use doc.Find(), which is a healthy complexity by itself.

In any case, I think you should back up a bit and get this one part working, whatever it is you are trying to do. Pick one specific place in the doc and start with a function or two, then plug it into the larger iteration routine. If you did that, we could help you much more effectively. It's hard to decipher a large block of code like you presented, at least quickly.

Thank you. To narrow it down, I want to find text that has the character format "Link" and add a gotolink hypertext marker. For example, in the phrase: "The quick brown fox jumped over the lazy dog," the word "over" has the character format "link" and I want it to click to somewhere else on the page.

I can find the character format in my document with this:

var doc = app.ActiveDoc;

function findLink(doc) { // looks for the character format Link

  charFmt = doc.GetNamedCharFmt("Link");

   

        if(charFmt.ObjectValid() == true)     {

        //Get the character format properties

        

        alert("Format found.");

        }

   

        //If we didn't find the character format, a warning....

        else alert("Could not find the Link character format!");

}

findLink(doc);

but I can't figure out how to get it to apply the gotolink marker.

I get it. Nice idea, but complicated.

In your code above, you are not actually finding anything; rather you are just retrieving the character format object from the document. To actually find a location where the format is applied, you would need something like this:

      var findParams = AllocatePropVals(2);
     
      findParams[0].propIdent.num = Constants.FS_FindCharTag;   
      findParams[0].propVal.valType = Constants.FT_String;   
      findParams[0].propVal.sval = fmtName; 
     
      findParams[1].propIdent.num = Constants.FS_FindWrap;   
      findParams[1].propVal.valType = Constants.FT_Integer;   
      findParams[1].propVal.ival = false; 
 
      var textRange = new TextRange();
      textRange.beg.obj = textRange.end.obj = doc.MainFlowInDoc.FirstTextFrameInFlow.FirstPgf; 
      textRange.beg.offset = textRange.end.offset = 0; 
      doc.TextSelection = textRange;

      textRange = doc.Find(textRange.beg, findParams);

Then, with a successful find, you could add the marker like this, where I included the code to apply the character format:

      var charFmt = doc.GetNamedCharFmt("Link");

      var marker = doc.NewAnchoredMarker(textRange.beg);

      var markerRange = new TextRange(marker.TextLoc, marker.TextLoc);

      markerRange.end.offset++;

      doc.SetTextProps(markerRange, charFmt.GetProps());

You would also need to set the marker type (Hyperlink) and the marker text (goto something). You would need your getText() method to finish that last part.

It gets complicated when you want to loop through a whole doc. You can put Find into a loop, but it seems that every time you modify the doc with a new marker, it resets the Find action and you end up finding and adding markers endlessly. You could do all the Finds first and put the results in an array, but the problem with that is you could mess up a text range in the array by adding a marker earlier in the same paragraph.

I experimented some but ran out of time. I was thinking of a routine to first delete all markers out of the whole doc, then add them back with a second recursive search. But I didn't come up with anything simple and like I said, I'm out of time for now. Perhaps you can experiment with this some more with the ideas above and come back with an idea on how the routine should work. I hope this helps.
