问题:

I would like to create a google map with search box on top like on this side: https://google-developers.appspot.com/... with the JavaScript API v3.

At the moment I use the following code to show a map by getting the latitude and longitude in the url (php get):

<?php

$latitude = $_GET['lat'];
$longitude = $_GET['long'];


?>
<!DOCTYPE html>
<html>
  <head>
  <script type="text/javascript">  
  </script>
    <meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
    <style type="text/css">
      html { height: 100% }
      body { height: 100%; margin: 0; padding: 0 }
      #map_canvas { height: 100% }

      #search-panel {
        position: absolute;
        top: 5px;
        left: 50%;
        margin-left: -180px;
        width: 350px;
        z-index: 5;
        background-color: #fff;
        padding: 5px;
        border: 1px solid #999;
      }
      #target {
        width: 345px;
      }


    </style>
    <script type="text/javascript"
      src="http://maps.googleapis.com/maps/api/js?key=XXXXXXXXXXX&sensor=true">
    </script>
    <script type="text/javascript">
      function initialize() {

          var input = document.getElementById('searchTextField');
          var image = 'pin.png';
          var myLatlng = new google.maps.LatLng(<?php echo "$latitude" ?>, <?php echo "$longitude" ?>);
        var mapOptions = {
          center: myLatlng,
          zoom: 15,
          mapTypeId: google.maps.MapTypeId.ROADMAP,
          streetViewControl: true,
        };




        var map = new google.maps.Map(document.getElementById("map_canvas"),
            mapOptions);


            var marker = new google.maps.Marker({
      icon: image,
      position: myLatlng,
      map: map,
      animation: google.maps.Animation.DROP,
      title:"You Location"

  });


      }
    </script>
  </head>
  <body onload="initialize()">
    <div id="map_canvas" style="width:100%; height:100%"></div>
  </body>
</html>

But I don't get it, to integrate the Search Box like on the named site!!!

Can someone help?

I edited the code to this, but I doesn't work!:

<?php

$latitude = $_GET['lat'];
$longitude = $_GET['long'];


?>

      var input = document.getElementById('target');
        var searchBox = new google.maps.places.SearchBox(input);
        var markers = [];

        google.maps.event.addListener(searchBox, 'places_changed', function() {
          var places = searchBox.getPlaces();


  });

    }); 

      }
    </script>
  </head>
  <body onload="initialize()">
  <div id="search-panel">
      <input id="target" type="text" placeholder="Search Box">
    </div>
    <div id="map_canvas" style="width:100%; height:100%"></div>
  </body>
</html>

回答1:

You also have to load the Places Search Box:

var searchBox = new google.maps.places.SearchBox(input, {
  bounds: defaultBounds // have to be defined first
});

Then you can listen to the places_changed event:

google.maps.event.addListener(searchBox, 'places_changed', function() {
      var places = searchBox.getPlaces();
      // do your stuff here
});

Have a look at the source code of the example page you posted to get an idea of what to do in there, for example drawing markers etc.

You can find more information in the SearchBox API Documentation.
