I am plotting an XY coordinate in my map using an OVF file to hit the MySQL
database.
I then have a button that calls a .js page and refreshes the layer...
As the XY changes in the database it appears to be tracking in the map
I want to take this one step further and test the recently plotted XY to see if
it s in the current extent. If not then recenter.
PART 1
BUITTON: Calls the .js page sets an interval and refreshes the layer "Database"
<service name="refreshLayers3" title="Refresh Layer every 2 Seconds"
type="internal" default="true" locked="true" command="setIntervalNow()"
icon="shared/images/toolbar/MapleGrove_Buttons/Reload.jpg"
highlight="shared/images/toolbar/MapleGrove_Buttons/Pictometry.jpg"/>
.js PAGE:
//setIntervalNow();
var varTest = -1;
function setIntervalNow()
{
varTest = setInterval("setIntervalNow2()", 3000);
}
function setIntervalNow2()
{
Events.triggerEvent('refreshlayer', 'Database');
}
PART 2
What I want to do is grab the current XY and test to see if its in the current
extent
If not then create another extent and zoom to it.
Right now I am having a hard time trying to join the two parts.
For this part I am launching the code from the Identify button which calls an
Ajax page and passes the Extent to a PHP page
<tr>
<td align="center" width='100'>Tracking Testing:</td>
<td style= "cursor:pointer" align="center"
onclick="javascript:getnewresults('XY_MapRecenter.php','[imgext]','[miny]','[maxx]','[maxy]')"><font
size='2' color='#007FFF' >Open Images</font></td>
</tr>
I can get test and make the new Extent but can only return the values to a tab
and then fire it off from a button....what I want to do is have this done
automatically...
I don't know how I can do this...
Thanks

Still confused on what you're trying to do. It sounds like your PHP code is
hitting the database to
get the xy's. You could poll that PHP page as necessary via AJAX and have it
return the xy data
as JSON. Then you use the JSON data accordingly to control GeoMoose by zooming
to a point or
whatever. I don't know if GeoMoose provides AJAX wrappers or not, that's a
question for that
another mailing list...
