<div><div dir="ltr">Hello folks,<br><pre>Thanks to Richard Greenwood, this function shows which layer is unselected in the layerswitcher control.<br><br>map.events.register('changelayer', null, function(evt){
if(evt.property === "visibility") {
alert(<a href="http://evt.layer.name" target="_blank">evt.layer.name</a> + " layer visibility changed to " + evt.layer.visibility );
}
});</pre>I'm wondering how I can save in a variable array the unselected layers. For instance I have layers "a", "b", "c" in the layerswitcher, so "a" is unselected and I want "b" and "c" saved in an array like myarray = [b,c]. Then, I can loop over this array to do some processes calling only layers "b" and "c".<br>
<br>I'll appreciate some ideas about this, thanks in advance,<br><br>Gery<br> </div></div>
