获取属性(邮政编码)并在Google地图API 3中使用


taking attribute (zip code) and using it in Google maps API 3

我有一个magento网站,我的产品就是业务。我想在产品页面上添加一个谷歌地图,需要有人帮我写代码。

我可以通过键入来调用邮政编码

<?php echo $_product->getpostcode() ?>

我已经从互联网上获取了代码,并试图将其整合到我的网站上。这是代码:

  <script src="https://maps.googleapis.com/maps/api/js?sensor=false"></script>
   <script>
  var geocoder;
  var map;
  var address = '<?php echo $_product->getpostcode() ?>'
  function initialize() {
    geocoder = new google.maps.Geocoder();
    var latlng = new google.maps.LatLng(-34.397, 150.644);
    var mapOptions = {
      zoom: 8,
      center: latlng,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    }
    map = new google.maps.Map(document.getElementById('map_canvas'), mapOptions);
  }
  function codeAddress() {
    var address = document.getElementById('address').value;
    geocoder.geocode( { 'address': address}, function(results, status) {
      if (status == google.maps.GeocoderStatus.OK) {
        map.setCenter(results[0].geometry.location);
        var marker = new google.maps.Marker({
            map: map,
            position: results[0].geometry.location
        });
      } else {
        alert('Geocode was not successful for the following reason: ' + status);
      }
    });
      }
    </script>
    <body onload="initialize()">
    <div id="map_canvas" style="width: 500px; height: 300px"></div>

目前,它正在代码中使用lat-long。如何将其更改为使用邮政编码?`

地图始终使用坐标。这就是地图的工作原理。如果您想使用邮政编码,您需要将其转换为坐标—该过程称为地理编码

您的代码中有一个地理编码函数,它目前不起作用,因为您没有一个名为address的元素,但它可以在使用时稍作调整。

您目前有一个名为address的全局变量,其中包含您的邮政编码,所以让您的地理编码函数使用它:

在函数initialize()的底部,添加对地理编码器函数的调用,并将全局变量传递给它

 map = new google.maps.Map(document.getElementById('map_canvas'), mapOptions);
 codeAddress(address);
}

更改该函数以接受参数:

function codeAddress(addy) {

然后使用它:

// var address = document.getElementById('address').value;
// The above line needs to be removed; the one below amended
geocoder.geocode( { 'address': addy}, function(results, status) {
//i have working function use it.
  function initialize() {
var address = "<?php echo $address?>";
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(50.317408,11.12915);
var myOptions = {
  zoom: 8,
  center: latlng,
mapTypeControl: true,
mapTypeControlOptions: {style: google.maps.MapTypeControlStyle.DROPDOWN_MENU},
navigationControl: true,
  mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("location-canvas"), myOptions);
if (geocoder) {
  geocoder.geocode( { 'address': address}, function(results, status) {
    if (status == google.maps.GeocoderStatus.OK) {
      if (status != google.maps.GeocoderStatus.ZERO_RESULTS) {
      map.setCenter(results[0].geometry.location);
        var infowindow = new google.maps.InfoWindow(
            { content: '<b>'+address+'</b>',
              size: new google.maps.Size(150,50)
            });
        var marker = new google.maps.Marker({
            position: results[0].geometry.location,
            map: map, 
            title:address
        }); 
        google.maps.event.addListener(marker, 'click', function() {
            infowindow.open(map,marker);
        });
      } else {
        alert("Address Not found");
      }
    } else {
      alert("Geocode was not successful for the following reason: " + status);
    }
  });
}
