Render all visible feature layers in a map invisible with click of element

JohnRichardson — Sun, 12 Dec 2021 00:27:21 GMT

I am struggling with this most basic operation ... please help!

Here is code snippet I am working with :

      $("#grayPic").click(function() { //eventually, this will render all layers in the map invisible
      var allGuys = map.allLayers;
      var i, currentLayer;
      for (i = 0, l = allGuys.length; i < l; i++) {
      currentLayer = allGuys[i];
      currentLayer.visible = false;
      };
      });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

John,

Try this:

$("#grayPic").click(function() {
 //eventually, this will render all layers in the map invisible
  map.allLayers.forEach(function(item){
    item.hide();
  };
});‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

John,

Sorry change it to:

$("#grayPic").click(function() {
 //eventually, this will render all layers in the map invisible
  map.allLayers.forEach(function(layer){
    layer.visble = false;
  };
});‍‍‍‍‍‍
