DOM Events

DOM Events provides an interoperable eventing mechanism. Hover over the menus below to view fly-out menus hooked up using addEventListener if your browser supports it (menus use opacity and border-radius).
var addSummaryListeners = function () { ... // Call "showSummary" on mouseover addEventListener("mouseover", showSummary, false); // Call "hideSummary" on mouseout addEventListener("mouseout", showSummary, false); } } }
