In my map there are numberof layers. I want my custom legends to show when the related layer feature is visible in the current map view. I am able to turn on/off the display of the legend according to display scale but I need to hide the legend if the feature is not in the map view even if it is in the range of display scale.
I go through the layer collection of the map. I tried to debug when the vector layer feature is visible in the map view but I get layer.features.length as always zero.
I need it total in terms of openlayers script. I do not want to utilize GeoExt.
Can anyone help on this?
