I have this function, to create a DIV on-the-fly. But now, I want to destroy this object on *onclick* event, but I just don't know how.

```
function creatediv(id) {

    var newdiv = document.createElement('div');
    newdiv.setAttribute('id', id);
    newdiv.onclick=function(){this=null;};  //bad function
    document.body.appendChild(newdiv);

} 

```

What am I missing?

Thanks
