Alert for transparency items

Hi Forum,

I got this from forum ,

I need a help to alert, for any type of  "transparency effects" appiled to the pageItems.

Instead of referring, transparencySettings.gradientSettings,

transparencySettings.opacity,

fillTransparencySettings,

objectTransparencySettings.

etc.,

items= app.activeDocument.pageItems.everyItem().getElements(); 

for (i = 0; i < items.length; i++) {

     if(items[i].transparencySettings == true) {

          items[i].itemLayer = app.activeDocument.layers.item("items");

alert("pageitems has transparency effects")

     } }

thanks for your help!
