I am using GeoMOOSE if that sheds new light on this... What I am trying to do is click a button. This calls a js page that runs some code every few seconds. Right now its simply refreshing a specific layer. I want the code to grab the extent of the current map I then use an XY to recreate a new extent. Then zoom to that extent.
I am getting the XY from a database. Testing to see if within current extent. If not I want it to recenter (zoom to new extent I calculated) Currently I am doing this in php...the only thing is that I cant figure out how to get the app to recenter from PHP. I can do it from a button (see below) but I need it to work automatically <h5 style="margin:0px; padding:0px;"><b>Zoom to View String:</b> <a href="javascript:Map.zoomToViewString(453633.29 + ',' + 4984898.68 + ',' + 464278.99 + ',' + 4995544.38)"><img src="shared/images/view.png" border="0" title="Click to Zoom Map to PID"></a> I have everything I need ( I think ) but need to figure out how to get the js page to retireve the extent, then I can fire to above off in javascript. That make sense....
