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
