I need to select all text frames in a document and to align text frames in verso pages to left margin and text frames in recto pages to right margin.

Hi Harish,

Try this.

var doc =app.activeDocument,
    _pages = doc.pages;
doc.viewPreferences.rulerOrigin = RulerOrigin.pageOrigin;   
for(var i =0;i<_pages.length;i++)
{
        txfms = _pages.textFrames.everyItem().getElements();

        for(var j =0;j<txfms.length;j++)
        {
            if(_pages.documentOffset % 2 == 1)

            {
                    var leftm  = _pages.marginPreferences.left,

                        framtoppos = txfms.geometricBounds[0];
                    txfms.move([leftm,framtoppos])
                }
            else
            {
                    var rightm  = _pages.marginPreferences.right,

                        w = doc.documentPreferences.pageWidth,
                        fmwidth = txfms.geometricBounds[3] - txfms.geometricBounds[1];
                    txfms.move(txfms.parentPage.name,[w-rightm-fmwidth-txfms.geometricBounds[1],0])
                }
        }
    }
