http://forums.adobe.com/thread/302996

I am on this page to find the relevant code,

--------------------------------------

app.addSubMenu({ cName: "Footer",cUser: "Set/Remove Footer", cParent: "File", nPos: 20 });

app.addMenuItem({ cName: "Set Date Time (Filename)", cParent: "Footer", cExec: "SetFooter(1)"});

app.addMenuItem({ cName: "Set Page ", cParent: "Footer", cExec: "SetFooter(2)"});

app.addMenuItem({ cName: "Set Both", cParent: "Footer", cExec: "SetFooter(3)"});

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

app.addMenuItem({ cName: "Remove Date Time (Filename)", cParent: "Footer", cExec: "RemoveFooter(1)"});

app.addMenuItem({ cName: "Remove Page", cParent: "Footer", cExec: "RemoveFooter(2)"});

app.addMenuItem({ cName: "Remove Both", cParent: "Footer", cExec: "RemoveFooter(3)"});

function SetFooter(ARG)

{

var re = /.*\/|\.pdf$/ig;

var FileNM = this.path.replace(re,"")+".pdf";

var Path = this.path;

var AcDate = new Date();

for (var p = 0; p < this.numPages; p++)

{

if (ARG==1 || ARG==3) {var fd = this.addField("xftDate", "text", p, [30,15, 290,30]);

fd.textSize=6; fd.value = util.printd("yyyy/mmm/dd, HH:MM", AcDate) + " (" + FileNM +")"; }

if (ARG==2 || ARG==3){var fp = this.addField(String("xftPage"+p+1), "text", p, [350,15,300,30]);

fp.textSize=6; fp.value = "Page: " + String(p+1)+ "/" + this.numPages; }

} }

function RemoveFooter(ARG)

{

if (ARG==1 || ARG==3) {var x = this.removeField("xftDate");}

if (ARG==2 || ARG==3) {for (var p = 0; p < this.numPages; p++)

{

var x = this.removeField(String("xftPage"+p+1)); }

} }

---------------------------------------
