How to remove each Footnote textframes in a page using indesign javascript

I tried it but the footnotes length

var doc = app.activeDocument;
var pagess = doc.pages;

for(var p=0; p<pagess.length; p++){
    var pgTxtFrames = pagess[40].textFrames;
    for(var t=0; t<pgTxtFrames.length; t++){
       // pgTxtFrames[t].remove();
        if(pgTxtFrames[t].footnotes.length >0){ 
            for(var f=0; f<pgTxtFrames[t].footnotes.length; f++){
             pgTxtFrames[t].footnotes[0].parentTextFrames[0].remove();
             }
         }
        }
    }


   

was Zero  but footnotes were present in each page
