i might've misunderstood your question first time ... probably you`re looking to check if 2 objects are duplicates without creating the duplicate programatically. if so this might give you an inside look. test it by creating a shape, selecting it, copying it and pasting it in place ... you can play with the ignoreProperties string to make the comparison more general:
var doc = app.activeDocument;
var sel = app.activeDocument.selection;
var ignoreProperties = "|name||width||height|";
function AreDuplicates(o1, o2) {
for(prop in sel[0]) {
try {
if(sel[0][prop] != sel[1][prop] && ignoreProperties.indexOf("|" + prop + "|") > -1) return false;
} catch(er) {}
finally { continue; }
}
return true;
}
if(AreDuplicates(sel[0], sel[1])) alert("Wheeee, they are sooooooooo duplicated!");
else alert("Damn and i really hoped that ... never mind!");
hope it helps;
cheers;
