Added some bounty so more people take a look at my question. Thank you.
I have been trying to utilize the jQuery UI Slider to control layer opacity in OpenLayers but I have an issue when trying to set the "value" option to anything other than the "max" value.
What I would like to see is the setOpacity method change my layer's opacity to 20% onload. However, the slider is shown in the correct position but the layer displays the "max" value of opacity (100%/opaque). Currently, a slide event triggers a change in opacity. I need to force the opacity of my WMS layers to be that of the manually set "value" options when the page loads.
Removed the any unnecessary code. One slider shown below. Your help is much appreciated!
