safari: get the word under the mouse pointer

i'm trying to find a clicked word in an onclick event handler.

somediv.onclick = function(event) {
    var w  = getClickedWord(event);
    alert(w开发者_如何学Go)
}

getClickedWord() uses range.moveToPoint for msie and event.rangeParent/offset for gecko, but Webkit seems to support neither. Any pointers?

Maybe you can try window.getSelection() , notice that this function returns a Selection object, so you should use it like following:

var sel = window.getSelection();
