[mapserver-users] oraclespatial query through CGI

Thu Apr 18 13:18:54 EDT 2002

I'm running the mapserver 3.5 CGI version and HTML template on a Linux system.

I followed Rod's guidance of Feb 11 and put a javascript function called DoQuery in my HTML file to call a Perl program (Rod's original version calls a PHP program, I figured it should work with Perl).

Now my question is how do I specify when this DoQuery function is called.  I'm still getting the error message of function not implemented when I execute the new HTML.

<script language="javascript">
function DoQuery( url_query, x1, y1, x2, y2 )
{
  size = imgsize.split( /\+/ );
  ext = imgext.split( /\+/ );

  nx = eval( size[0] ) - 1;
  ny = eval( size[1] ) - 1;

  minx = eval( ext[0] );
  miny = eval( ext[1] );
  maxx = eval( ext[2] );
  maxy = eval( ext[3] );

  qx1 = x1*(maxx - minx)/nx + minx;
  qx2 = x2*(maxx - minx)/nx + minx;

  qy1 = (ny - y1)*(maxy - miny)/ny + miny;
  qy2 = (ny - y2)*(maxy - miny)/ny + miny;

  document.location = 'http://localhost/cgi-bin/querymap.pl?qx1=' + qx1 + '&qy1=' + qy1 + '&qx2=' + qx2 + '&qy2=' + qy2;
}
