Hide/Show layers with Javascript

Hello,

I am trying to find a Javascript method for hiding/showing layers in a pdf document. I would like to be able to use an if/else statement to set the visibility of multiple layers.

Let's say I have 5 layers on a single page, all set to hidden by default. This page also has a field with 5 options relating to each of the 5 layers. Once an option is selected, an if/else will use this method to set the appropriate layer to visible.

Thank you!
