<p class=MsoNormal>HI again all,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m working on a project where I’m trying to do
the same thing as the shapexy example linked from
http://mapserver.org/output/imagemaps.html<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve got an html imagemap working, and enough
javascript together that it correctly concatenates a link, but the link
doesn’t end up working…<o:p></o:p></p>
<p class=MsoNormal>The part I don’t understand how to get the map working
in map mode. I’m not understanding the “ids” variable that is
getting passed to mapserver. Are the id’s a field in the data set? I
don’t see any documentation for it anywhere, and when I pass it, I just
get my map back without anything selected. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Again, thanks in advance for your help.<o:p></o:p></p>
<p class=MsoNormal>Hope everyone had a wonderful thanksgiving.<o:p></o:p></p>
