Dear all, I have create a tool on javascript and html. I tried to use the xml tool from ucsc and flymine. I would like to know if it is possible to replace <inputs action="http://www.flymine.org" check_values="false" method="get"> <display>go to Flymine server $GALAXY_URL</display> <param name="GALAXY_URL" type="baseurl" value="/tool_runner?tool_id=flymine" /> </inputs> By something like onclick it will display a pop up windows instead of opening the html adress on the same window. Best regards, Mohamed
