向谷歌地图添加多个标记-前端问题

Adding multiple markers to Google Map(向谷歌地图添加多个标记)

本文介绍了向谷歌地图添加多个标记的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我希望为 Google 地图 v3 API 中列出的每个企业添加标记在这个页面上在右上角.

I'm looking to add markers for each business listed to a Google map v3 API on this page in the top right hand corner.

我不确定如何为多个邮政编码执行此操作，但我们目前在个别业务页面对存储在数据库中的动态邮政编码使用 URLencode.

I'm not sure how to do this for multiple postcodes, but the one we currently use on the individual business pages use a URLencode for the dynamic postcodes stored in the database.

这是我们用于各个页面的代码:

Here's the code we use for the individual pages:

<script src="http://maps.googleapis.com/maps/api/js?q=London&key=AIzaSyBaPEDyFbbnWjtvT8W3UBOM34Y7g6vK69A&sensor=false"></script>

    var map;
    function initialize() {
      var mapOptions = {
        zoom: 15,
        center: new google.maps.LatLng(51.511214,-0.119824),
        mapTypeId: google.maps.MapTypeId.ROADMAP
      };
      var geolocate = function(address, callback) {
            $.ajax({
                    url: "http://maps.googleapis.com/maps/api/geocode/json",
                    data: {
                        "sensor": true,
                        "address": address
                    },
                    dataType: "json",
                    success: function(d) {
                        if (d.status == "ZERO_RESULTS") callback(false);
                        if (d.results && d.results[0] && d.results[0].geometry) {
                            callback({
                                "ne": d.results[0].geometry.bounds.northeast,
                                "sw": d.results[0].geometry.bounds.southwest,
                                "center": d.results[0].geometry.location
                            });
                        }
                        else callback(false);
                    }
                });
      };
      map = new google.maps.Map(document.getElementById('map-canvas'),
          mapOptions);
      geolocate("<%=server.URLEncode(""&rsAdvert("ContactPostcode"))%>", function(c) {
            map.setCenter(new google.maps.LatLng(c.center.lat, c.center.lng));
     });
    }
    google.maps.event.addDomListener(window, 'load', initialize);

$('#myModal').on('shown', function () {
  google.maps.event.trigger(map, 'resize');
})

该页面的邮政编码是在 ASP 中生成的:

The postcodes for that page are generated in ASP:

    if rsDB_Ads("ContactPostcode") <> "" then
        strTempHTML = "[ContactPostcode]"
        strDB_AdvertItem = Replace(strDB_AdvertItem, "<!--ContactPostcode-->", strTempHTML)
    Else
        strDB_AdvertItem = Replace(strDB_AdvertItem, "<!--ContactPostcode-->", "")
    End if

推荐答案

只是开始，这里是如何管理多个标记.(将代码复制并粘贴到 html 文件中，它就可以工作了......)然后您可以通过经典的 asp 从数据库等中写出位置来调整代码:

Just for a start, here is how to manage multiple markers. (copy & Paste the code into a html file and it works ...) You can then adapt the code by writing out the locations from a db etc. via classic asp:

    <!DOCTYPE html>
    <html>
    <head>
      <meta http-equiv="content-type" content="text/html; charset=UTF-8" />
      <title>Google Maps Multiple Markers</title>
      <script src="http://maps.google.com/maps/api/js?sensor=false"
              type="text/javascript"></script>
    </head>
    <body>
      <div id="map" style="width: 1000px; height: 1000px;"></div>

      <script type="text/javascript">
        var locations = [
          ['Stadtbibliothek Zanklhof', 47.06976, 15.43154, 1],
          ['Stadtbibliothek dieMediathek', 47.06975, 15.43116, 2],
          ['Stadtbibliothek Gösting', 47.09399, 15.40548, 3],
          ['Stadtbibliothek Graz West', 47.06993, 15.40727, 4],
          ['Stadtbibliothek Graz Ost', 47.06934, 15.45888, 5],
          ['Stadtbibliothek Graz Süd', 47.04572, 15.43234, 6],
          ['Stadtbibliothek Graz Nord', 47.08350, 15.43212, 7],
          ['Stadtbibliothek Andritz', 47.10280, 15.42137, 8]
        ];

        var map = new google.maps.Map(document.getElementById('map'), {
          zoom: 13,
          center: new google.maps.LatLng(47.071876, 15.441456),
          mapTypeId: google.maps.MapTypeId.ROADMAP
        });

        var infowindow = new google.maps.InfoWindow();

        var marker, i;

        for (i = 0; i < locations.length; i++) {
          marker = new google.maps.Marker({
            position: new google.maps.LatLng(locations[i][1], locations[i][2]),
            map: map
          });

          google.maps.event.addListener(marker, 'click', (function(marker, i) {
            return function() {
              infowindow.setContent(locations[i][0]);
              infowindow.open(map, marker);
            }
          })(marker, i));
        }
      </script>
    </body>
    </html>
