[OpenLayers-Users] Quickly hiding and showing features

[Heidt, Christopher M.]

You can also play with the feature style.
You can make a 'hidden' style that turns the opacity down to 0.
Then your slider could change the render intent on certain features.

It really just depends on if your are trying to hide a bunch at once or a few at a time.

Hi Nicholas,

I had the same problem some minutes ago and i put my features on different layers and for every "slider step" i hide/show a corresponding layer. I did this whith calling layer.setVisibility()

Betreff: [OpenLayers-Users] Quickly hiding and showing features

I have a slider whose value I would like to link directly to what vector features appear on my map (i.e., as the user moves the slider, I would like certain features to appear/disappear). 

Is the best way to do this to simply call add/removeFeatures on the layer, or is there a way for me to only toggle their visibility?

Thanks,
  -Nicholas
