I want to display multiple marker in google maps with the maker has its own info windows. The problem is when I click either of the marker only one info windows will come out(the info windows for the marker that I click not display).And one more problem is when the info window come out, it not smooth(there is like a box white box at the back also appeared)

enter image description here

// map center
var center = new google.maps.LatLng(2.855262784366583, 105.4302978515625);

// marker position
//var factory = new google.maps.LatLng(2.855262784366583, 105.4302978515625);

function initialize() {
  var mapOptions = {
    center: center,
    zoom: 7,
    mapTypeId: google.maps.MapTypeId.ROADMAP

  };

         // Create a <script> tag and set the USGS URL as the source.
         var script = document.createElement('script');
         // This example uses a local copy of the GeoJSON stored at
         // http://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/2.5_week.geojsonp
         script.src = 'https://developers.google.com/maps/documentation/javascript/examples/json/earthquake_GeoJSONP.js';
         document.getElementsByTagName('head')[0].appendChild(script);
  var map = new google.maps.Map(document.getElementById("map-canvas"),mapOptions);

  // Loop through the results array and place a marker for each
     // set of coordinates.
     window.eqfeed_callback = function(results) {
       for (var i = 0; i < results.features.length; i++) {
         var coords = results.features[i].geometry.coordinates;
         var latLng = new google.maps.LatLng(coords[1],coords[0]);
         var marker = new google.maps.Marker({
           position: latLng,
           map: map
         });



         // InfoWindow content
         var content = '<div id="iw-container">' +

  • Your issue is a common problem with multiple markers initialized in a loop. One example of a fix using function closure is in the duplicate: [Google Maps JS API v3 - Simple Multiple Marker Example](https://stackoverflow.com/questions/3059044/google-maps-js-api-v3-simple-multiple-marker-example). – geocodezip Jan 04 '18 at 03:30

Simplest fix for your code. Change:

 // This event expects a click on a marker
 // When this event is fired the Info Window is opened.
 google.maps.event.addListener(marker, 'click', function() {
   infowindow.open(map,marker);
 });

To:

 google.maps.event.addListener(marker, 'click', function() {
   infowindow.open(map,this);
 });

The this in the marker click function is the marker.

That will make the InfoWindow open on the clicked marker. But as far as I can tell all the InfoWindows have the same content, which isn't very useful.
