how script for select rectangle in indesign

Oh, sorry about that, I do apologise.

Try this snippet. I use it in my script to select all rectangles in an active InDesign file. It's part of a larger script that goes through a document and removes any frames that are blank. For your purposes, this should be what you're after.

var myGraphicFrames = app.activeDocument.rectangles;
for (i=myGraphicFrames.length-1; i>=0; i--) {
//do your thing here
}

However, this question was asked in the general InDesign forum. You may get more targeted and better answers in the InDesign Scripting subforum.

pleas more discreption.
