单击时如何获取 id 并删除它？ 谷歌地图 V3

Question

Here is my code...I try to put event listener but the console says:

markers.addListener is not a function

Here is my code..... https://jsfiddle.net/1LwLczgr/1/

//The problem :(
markers.addListener('click', function() {
      var marker = this;
      alert(this.id+"alasddsasdkasdl");
});



<!--My API-->
<script async defer type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=AIzaSyBZiX9quA0AJiAFuoxrogRYObImmbCa-6g&signed_in=true&libraries=geometry,places&callback=initMap"></script>

Answer 1

markers is an Array object. Can't we do:

$.each(markers, function(index, value) {
// Add listener here? 
});

Reference: http://api.jquery.com/jquery.each/

Or in plain JavaScript:

for(var i = 0; i < markers.length; i++)
{
// Add listener here? 
}

Edit - to the question - and then inside DeleteMarkers()'s function?

• Remove listener via looping
• Clear the array

Wouldn't that help? Please give it a try and let us know the result.

You can only add Google Maps click listeners to a Google Maps objects that support click events (like a google.maps.Marker . markers is not a google.maps.Marker , it is an Array . Array s don't have the method .addListener .

One option would be to add the click listener to the marker when you create it:

// Adds a marker to the map and push to the array.
function addMarker(location) {
  var marker = new google.maps.Marker({
    id:count,
    position: location,
    map: map
  });
  marker.addListener('click', function() {
    var marker = this;
    alert(this.id+"alasddsasdkasdl");
  });
  markers.push(marker);
  countmarkers ++;
  count ++;
}

而不是addListener()类型addEventListener() 。

It is working for me after fixing few things. The script tag needs to be closed. The addListener was required on markers[0] (not on the markers array itself). I moved the initMap function so that it doesn't complain. I uncommented the event listener. It worked.
