如何动态地将信息窗口添加到Google地图上的标记？

Question

下面的代码是我针对此问题的设置，效果很好

var map;
var markers   = [];
var contentString = '<h1>This is the Title!</h1>';

function initialize() {
  var losAngeles = new google.maps.LatLng(34.0500, -118.2500);
  var mapOptions = {
    zoom: 10,
    center: losAngeles,
    disableDefaultUI: true,
    mapTypeControlOptions: google.maps.MapTypeId.SATELLITE
  };
  map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
}

function addMarker(location) {

  var markerOptions = {
    position: location,
    map: map
  }
  var marker = new google.maps.Marker(markerOptions);
  markers.push(marker);
}

function setAllMap(map) {
  for (var i = 0; i < markers.length;i++) {
    markers[i].setMap(map);
  }
}

function clearMarkers() {
  setAllMap(null);
}

function showMarkers() {
  setAllMap(map);
}

function deleteMarkers() {
  clearMarkers();
  markers = [];
}

function addInfoWindow() {
  infowindow = new google.maps.InfoWindow({
    content: contentString
  });
}



google.maps.event.addDomListener(window, 'load', initialize);



$(document).ready(function() {

  $('#thurs').on('click', function() {
    deleteMarkers();
    // Loads the markers
    addMarker(new google.maps.LatLng(34.0500, -118.2500));

    markers[0].infowindow = new google.maps.InfoWindow({
      content: contentString
    });

    console.log(markers[0].infowindow);
    google.maps.event.addListener(markers[0], 'click', function() {
      this.infowindow.open(map,this);
    });

    setAllMap(map);
  });
})

现在，我的问题是为每个标记添加多个标记和一个相应的信息窗口。 我的代码（jQuery）如下所示：

for(var i=0;i<locations.length;i++) {
      if(locations[i].start.slice(0, 10) == "2015-04-10") {
        addMarker(new google.maps.LatLng(parseFloat(locations[i].lat), parseFloat(locations[i].lng)));
      }
    }

    console.log(markers);

    for(var i=0;i<markers.length;i++) {
      markers[i].infowindow = new google.maps.InfoWindow({
        content: contentString
      });
    }


    for(var i=0;markers.length;i++) {
      console.log(markers[i].infowindow);
      google.maps.event.addListener(markers[i], 'click', function() {
        markers[i].infowindow.open(map,markers[i]);
      });
    }

当我这样做时，出现以下错误：

遗漏的类型错误：未定义无法读取属性“信息窗口”。

问题是您不应在事件侦听器中引用“ i”。 当您单击标记时，我是markers.length。 以下事件侦听器将起作用：

    google.maps.event.addListener(markers[i], 'click', function() {
      this.infowindow.open(map, this);
    });

这是一个代码片段来演示：

 <!DOCTYPE html xmlns:xlink="http://www.w3.org/1999/xlink">> <head lang="en"> <meta charset="UTF-8"> <style> html, body, #map-canvas { height: 100%; margin: 0px; padding: 0px } </style> <script src="https://maps.googleapis.com/maps/api/js?v=3.exp"></script> <script> var map; var markers = []; var contentString = '<h1>This is the Title!</h1>'; function initialize() { var losAngeles = new google.maps.LatLng(34.0500, -118.2500); var mapOptions = { zoom: 10, center: losAngeles, disableDefaultUI: true, mapTypeControlOptions: google.maps.MapTypeId.SATELLITE }; map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions); addMarkers(); } function addMarker(location) { var markerOptions = { position: location, map: map } var marker = new google.maps.Marker(markerOptions); markers.push(marker); } var locations = [{ start: "2015-04-10", lat: 34.0500, lng: -118.2500 }]; function addMarkers() { for (var i = 0; i < locations.length; i++) { if (locations[i].start.slice(0, 10) == "2015-04-10") { addMarker(new google.maps.LatLng(parseFloat(locations[i].lat), parseFloat(locations[i].lng))); } } for (var i = 0; i < markers.length; i++) { markers[i].infowindow = new google.maps.InfoWindow({ content: contentString }); google.maps.event.addListener(markers[i], 'click', function() { this.infowindow.open(map, this); }); } } google.maps.event.addDomListener(window, 'load', initialize); </script> </head> <body> <div id="map-canvas"></div> </body> </html>
