Try this,
var doc = app.activeDocument, txfms = doc.textFrames, left;
doc.viewPreferences.rulerOrigin = RulerOrigin.pageOrigin;
for(var i =0;i<txfms.length;i++)
{ if(txfms[i].parentPage.documentOffset % 2 != 0) { left = txfms[i].parentPage.marginPreferences.right; } else { left = txfms[i].parentPage.marginPreferences.left; } txfms[i].move([left,txfms[i].geometricBounds[0]]); }
