Instead, I want to actually fire off a function to do something with that link. Right now I am using something like so, which actually does work. Just want to confirm if there is a better way <a href="" id="permalink">permalink</a> $("#permalink").click(function() { doSomethingWithPermalink($(this).attr("href")); return false; }); For example, I might want to replace the href with '<div id="permalink"></div>'. In which case, how would I get the current value of permalink? -- Puneet Kishor_______________________________________________ Users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/openlayers-users
