turing on an off layers

[idastorm]

After struggling a little with the time slider demo (issue #20 - new post soon), upon a request from @johaahlf , I have been looking at turning on and off different place categories (defined by different IDs in the style.json file), but without success. I am hoping that @klokan or someone else can look at it and give me feedback? It is just a test for turning on and off the major settlements.

This is the key lines. The whole file is also attached.

var hideLayer = function(layerId) {
if (!STYLE_JSON) return;
var styleObj = JSON.parse(JSON.stringify(STYLE_JSON));

//accessing the style sheet with the ID places_major_settlement. Updated style version where set to visible on default (all boxes checked)

styleObj[layerId].layout.visibility = 'none';
map.setStyle(styleObj);

};
