    Assigning a unique ID for each annotation in JS

    kalabal

      Hi everyone,


      I made a JS code to export all the annotations in a .pdf file to a .csv file and it works fine. I also need to assign a unique ID number for each row similar to a database table but couldn't figure a way out.


      The issue is that if a user deletes an annotation, ID numbers of annotations after the deleted annotation will change if I use value of "i" in the "for" loop. Somehow I need to store the ID numbers in each annotation.


      Let's say I have 3 annotations in a .pdf file, and run the code below;


      this.syncAnnotScan();  
      var annots = this.getAnnots()  
      for ( var i= 0; i< annots.length; i++) {  
          console.println(i+1);  
          console.println("Type:"+annots[i].type);  
          console.println("Text:"+annots[i].contents);      
          console.println("-----");  
      } 
      

       

      Results are ;

       

      1
      Type:Text
      Text:Comment-1
      -----
      2
      Type:Text
      Text:Comment-2
      -----
      3
      Type:Text
      Text:Comment-3
      -----
      

       

      If I delete the annotation-2, then the results will be;

       

      1
      Type:Text
      Text:Comment-1
      -----
      2
      Type:Text
      Text:Comment-3
      -----
      

       

      I'm trying to keep the ID number "3" for the comment-3 even if I delete the comment-2. Is there a simple way to do that? Any kind of help is appreciated.

       

      Regards.
