javascript - Close all other InfoWindows when one is clicked -


i trying amend below code other infowindows closed when 1 clicked, 1 open @ once. works great, besides fact user can open 20 infowindows. help.

function infowindow(marker, map, title, address, url) {  google.maps.event.addlistener(marker, 'click', function () {   var html = "<div><h3>" + title + "</h3><p><a href='" + url + "'>read more</a></p></div>";     iw = new google.maps.infowindow({         content: html,         maxwidth: 350     });     iw.open(map, marker); }); }

if want 1 infowindow, create 1 , move between markers on click event.

updated code:

// global infowindow var iw = new google.maps.infowindow({   maxwidth: 350 });  function infowindow(marker, map, title, address, url) {   google.maps.event.addlistener(marker, 'click', function() {     var html = "<div><h3>" + title + "</h3><p><a href='" + url + "'>read more</a></p></div>";     // set content (saved in html variable using function closure)     iw.setcontent(html);     // open infowindow on marker.     iw.open(map, marker);   }); }

proof of concept fiddle

code snippet:

var geocoder;  var map;    function initialize() {    var map = new google.maps.map(      document.getelementbyid("map_canvas"), {        center: new google.maps.latlng(37.4419, -122.1419),        zoom: 13,        maptypeid: google.maps.maptypeid.roadmap      });    var marker1 = new google.maps.marker({      position: new google.maps.latlng(37.4419, -122.1419),      map: map    });    infowindow(marker1, map, "title1", "address1", "http://www.google.com")    var marker2 = new google.maps.marker({      position: new google.maps.latlng(37.44, -122.14),      map: map    });    infowindow(marker2, map, "title2", "address2", "http://www.yahoo.com")      }  google.maps.event.adddomlistener(window, "load", initialize);  // global infowindow  var iw = new google.maps.infowindow({    maxwidth: 350  });    function infowindow(marker, map, title, address, url) {    google.maps.event.addlistener(marker, 'click', function() {      var html = "<div><h3>" + title + "</h3><p><a href='" + url + "' target='_blank'>read more</a></p></div>";      // set content (saved in html variable using function closure)      iw.setcontent(html);      // open infowindow on marker.      iw.open(map, marker);    });  }
html,  body,  #map_canvas {    height: 100%;    width: 100%;    margin: 0px;    padding: 0px  }
<script src="https://maps.googleapis.com/maps/api/js"></script>  <div id="map_canvas"></div>
