Question

How can I pass a class name to the YUI2tooltip: http://developer.yahoo.com/yui/examples/container/tooltip.html instead of an ID?

I attempted to do this:

YAHOO.example.container.tt1 = new YAHOO.widget.Tooltip(
    YAHOO.util.Dom.getElementsByClassName('annotation-rating'), {
        context:"ctx",
        text:"My text was set using the 'text' configuration property"});

YAHOO.example.container.tt2 = new YAHOO.widget.Tooltip(
    YAHOO.util.Dom.getElementsByClassName('annotation-rating'), {
        context:"link" });

Answer 1

Since YAHOO.widget.tooltip can only accept one element, the selector needs to be more specific:

YAHOO.util.DOM.getElementsByClassName(className, tagName, rootNode)
