The Openlayers javascript mapping library has support for adding tooltips for images used as map markers. The tooltip is set simply by defining the title for the image It works fine in both IE and Firefox, but doesn't work in Safari or Chrome As documented here in the API http://dev.openlayers.org/apidocs/files/OpenLayers/Feature/Vector-js.html Functionality was added under this ticket to Openlayers http://trac.openlayers.org/ticket/1946 With this example, the redish icon at the top has should have a title tooltip http://www.openlayers.org/dev/examples/vector-features.html
On the example page[1], hover over the red polygon in the top-right area of the map for a <title>-tooltip. The problem does occur for me in Safari 5, but not in Chrome 11, both using Windows Vista. Could you download a WebKit nightly to see if it's still an issue? http://nightly.webkit.org/ [1] http://www.openlayers.org/dev/examples/vector-features.html
Just tried this out in Safari 5.0.3 on Windows 7 and it now works, closing
