Script for deleting objects on pasteboard

Question

Anyone have a script that deletes all objects and text outside the page (or margins)?

Answer 1

Unfortunately in my Indi CS6 any pasteboard and spread item is "instance of spread".
So i consider geometrical bounds:
myDocument = app.activeDocument
cur_Ruler = myDocument.viewPreferences.rulerOrigin;
with(myDocument.viewPreferences){
    rulerOrigin = RulerOrigin.spreadOrigin;}
myDocument.zeroPoint = [0,0];
aWidth = myDocument.documentPreferences.pageWidth*2+10;
var objs = app.documents[0].pageItems.everyItem().getElements();
while(obj=objs.pop()){
a_left = obj.geometricBounds[1];
a_right = obj.geometricBounds[3];
     if(a_right <0 || a_left > aWidth){obj.remove()}
with(myDocument.viewPreferences){
    rulerOrigin = cur_Ruler} //back to the RulerOrigin
