Print File Name with pdf Document

I have modified Java Script. This is to make footer as the bookmark name of each pages(only applies 1st level bookmarks). I use this script when I merge many files into one PDF.

Please see below:

=======================
app.addSubMenu({ cName: "BMKFooter",cUser: "BookMark Footer", cParent: "File", nPos: 21 });

app.addMenuItem({ cName: "Set", cParent: "BMKFooter", cExec: "SetFooter(9)"});

app.addMenuItem({ cName: "-------------------------------", cParent: "BMKFooter",cExec: "{}"});

app.addMenuItem({ cName: "Remove", cParent: "BMKFooter", cExec: "RemoveFooter(9)"});

//Set/remove Footer
function SetFooter(ARG)
{
var bmk = this.bookmarkRoot;
var BMKName;
var lastBMKPage=0;
var currentBMKPage=0;
var p=0;

if(bmk.children != null){ 

for(var i = 0; i < bmk.children.length; i++){ 

BMKName=bmk.children.name;

if(i<=bmk.children.length-2){
bmk.children[i+1].execute();
lastBMKPage = this.pageNum-1; }
else {lastBMKPage = this.numPages -1;}

for ( p = currentBMKPage; p <= lastBMKPage; p++){

var aRect = this.getPageBox("Crop",p);
var TotWidth = aRect[2] - aRect[0]
if (ARG==9)
  {var  fd = this.addField(String("xftDate"+p+1), "text", p, [30+TotWidth/2,15, TotWidth-30,40]);
  fd.value = " " + BMKName +" "; //print bookmark name
  fd.textSize=10; fd.readonly = true;
  fd.alignment="right";
  }
} 

currentBMKPage = lastBMKPage +1;
} 

}}

function RemoveFooter(ARG)
{
if (ARG==9)
{for (var p = 0; p < this.numPages; p++)
{var x = this.removeField(String("xftDate"+p+1));}
}
//if (ARG==9)
//{ for (var p = 0; p < this.numPages; p++)
//{var x = this.removeField(String("xftPage"+p+1)); }
//if (ARG<=3 || ARG==9) {var x = this.removeField("xftRem");}
//}
}

This is very late response. But I hope this is helpful for you.
