Hi afrika,
the div is an object, can not use div+"string". Please try the code below, I added a <span> target into this div to shows your custom text.
for(var i=0;i<photos.length;i++)
{
var div=this.CreatePhotoDiv(photos[i]);
this.AttachItemEvent(div);
var span1=document.createElement("span");
span1.innerHTML="some text";
div.appendChild(span1);
this.dng_photolist.appendChild(div);
}
Regards,
Ken
