Hi,<br><br>I suspect that when map1 moves, it updates map2, which in turn updates map1, which updates map2...etc..<br><br>Add something like this:<br>var c1, c2, z1, z2;<br>var updatingMap1 = false,updatingMap2 = false;<br>map1.events.register("moveend", map1, function() {<br> if(!updatingMap2){<br> c1 = this.getCenter();<br> z1 = this.getZoom();<br> updatingMap1 = true;<br> map2.panTo(c1);<br> map2.zoomTo(z1);<br> updatingMap1 = false;<br> }<br>});<br>map2.events.register("moveend", map2, function() {<br> if(!updatingMap2){<br> c2 = this.getCenter();<br> z2 = this.getZoom();<br> updatingMap2 = true;<br> map1.panTo(c2);<br> map1.zoomTo(z2);<br> updatingMap2 = false;<br> }<br>}); <br><br>What I try to do (haven't tested it) is to prevent to update map2 when moving in map2.<br><br>Good luck!<br><br>Met vriendelijke groet,<br><br>Meine Toonen<br>B3Partners BV<br>Tel: 030 214 2083<br><blockquote style="padding-left: 5px; margin-left: 5px; border-left: #0000ff 2px solid; margin-right: 0px"><hr><b>From:</b> canduc17 [mailto:candini@meeo.it]<br><b>To:</b> users@openlayers.org<br><b>Sent:</b> Tue, 20 Dec 2011 15:07:31 +0100<br><b>Subject:</b> [OpenLayers-Users] Re: Synchronize position and zoom of two maps<br><br>I have tryed with the following:<br>
<br>
var c1, c2, z1, z2;<br>
map1.events.register("moveend", map1, function() { <br>
c1 = this.getCenter();<br>
z1 = this.getZoom();<br>
map2.panTo(c1);<br>
map2.zoomTo(z1);<br>
});<br>
map2.events.register("moveend", map2, function() { <br>
c2 = this.getCenter();<br>
z2 = this.getZoom();<br>
map1.panTo(c2);<br>
map1.zoomTo(z2);<br>
});<br>
<br>
It seems to work but from time to time maps get frozen and firebug (firefox<br>
plugin) reports me the error "too much recursion".<br>
If I comment out map2 related event I have no problems, but the<br>
synchronization is only if I pan/zoom map1 and I would like to make it<br>
possible also for map2.<br>
<br>
Any ideas on how to solve this?<br>
