Hi List,
i got this problem. Im trying dynamically change min and maxscale for
layers. So for start i set maxScale=100000.
var layer = new o.Layer.WMS(name, url, {params},{...maxScale:100000,
minScale:500000});
Then i add value 150000
/*button onclick event*/
layer.maxScale = document.getElementById("maxScale_value").value; //150000;
OK , everything works fine. I can see layer from scale 500K to scale 150K.
But when i change the value less then maxScale. for example to 50 000, it
doesnt work. i can see layer from 500K to 100K.
Then i tried something like this:
var layer = new o.Layer.WMS(name, url, {params}); // without max/minScale
map.events.register("move", map, function(){
if(layer.maxScale == 500) // this is the default maxScale value
{
layer.maxScale = 100000;
layer.minScale = 500000;
}
})
and then the same button click event
layer.maxScale = document.getElementById("maxScale_value").value; //50000;
That is working for me. But there is another new problem. If i have layer in
scales from 100000 to 500000 and i zoom to scale 525000 i cant see the layer
(that's good), but when i launch browser console (F12), in Network list i
can see, that the layer is still loaded in background.
Any idea how to avoid this problem?
Best regards.
