Get Zoom level of map for use in centerAndZoom()

[DavidMelville]

Hi all,

For the purposes of synchronizing two maps on the same webpage, how can I get the zoom level of one map to use in the method centerAndZoom() of the other map?

Thanks is advance,
Dave

Take a look at the compare maps sample:  http://www.arcgis.com/home/webmap/templates/Compare/Configure/index.html

Relevant code is the syncMapLocations() function here:  http://www.arcgis.com/home/webmap/templates/Compare/Configure/javascript/layout.js

cant you just use

this.map2.setLevel(this.map.getLevel()));

assuming they use the same tiling scheme?

you could even put it in an event listener for onextentchange

dojo.connect(this.map, "OnExtentChange", this, "changeMap2");

function: changeMap2(){
this.map2.setLevel(this.map.getLevel()));
}

pardon my terrible pseudo code.
