Here Api Clustering Error: "addlayer Is Not Defined"

I am try to use clastering in my aplication but I am get a error addLayer is not defined'. I have no Idea how to resolve this issue. I just copy and paste this sample function from

Solution 1:

You asked this question a second time as: "Try to create a cluster unsing a sample but addLayer got undefinied" which doesn't include some of the details in this question. Given the additional edit / context you made on this question however, it would seem you are adding an event listener in which map is probably out of scope or not yet defined for visibility inside the anonymous function.

document.querySelector(".camera-box").addEventListener("click", function() {
    if (document.getElementsByClassName("camera-marker-position")[0] === undefined) {
      map.addObject(cameraMarker);
      self.startClustering(map, coordinate);
    } else {
      map.removeAll();
    }
  });

You could do a typing check to see if map has been defined when the click event occurs and/or confirm whether it is an H.map. Without seeing the full listing, it may also be the case that you have not made map a global variable but instead declared it somewhere else in the page initialization so is out of scope when the click event is fired.

You can check JavaScript callback scope for details on closures where you could provide the map to the event when declaring the function. For more general information: JavaScript HTML DOM EventListener
