javascript - Button for layers are always in active state, legend persists for 1st layer when 2 layers are added -

-

i have mapbox , tilemill layer problem:

check out code here: http://bl.ocks.org/marishaf/3cc9bfbeb412c1120e93

layer buttons they're in "active" mode, although still load , unload layers.

legends load each layer (legends exist public land , zoning layers), if load both , try remove both layers, legend persists first layer loaded.

the legend persists tooltips. example, if load layer legend first (only happens if layers loaded in order) , layer tooltips (for example point source pollution) , mouse on point tooltip called , try remove layer legend, legend persists.

  1. remove "link.classname = 'active';" before onclick function.
  2. change "if (map.haslayer(layer))" statement more similar "else" 1 ("layer" instead of "thelayer" , 1 "classname" change).

snippet:

link.href = '#'; // remove line here link.innerhtml = name;   link.onclick = function(e) {     e.preventdefault();     e.stoppropagation();      if (map.haslayer(layer)) {         map.removelayer(layer);         map.removelayer(gridlayer);         // had "thelayer", should "layer":         map.legendcontrol.removelegend(layer.gettilejson().legend);         // change 2 lines here following:         this.classname = '';     } else {         map.addlayer(layer);         map.addlayer(gridlayer);         this.classname = 'active';         map.legendcontrol.addlegend(layer.gettilejson().legend);      }        thelayer = layer;    };

sorry messy explanation, asking 2 questions @ once, , cleanest way can think answer.
