Google Maps API文本搜索位置

我在屏幕上设置了谷歌地图，但我想要的是允许用户输入一个位置，然后重定向到该位置。我在下面的页面https://developers.google.com/maps/location-based-apps的第一个地图中有一个示例，您可以在其中输入位置。我目前的代码是这样的，但我找不到有关如何输入文本框以允许刷新新位置的地图的信息。Google Maps API文本搜索位置

<script type="text/javascript"> 

    //Javascript used to add Elements to the maps 
    // Arguments latitude, longitude, name 
    function addMarkersToMap(eventTitle,eventLongitude,eventLatitude)

你在找什么是Geocoding没有地理位置。

以下功能findLocation()使用地理编码从文本框address中查找位置。它使用API的版本3，而不是在接受的答案中的V2。 Maps API的Version 2已被弃用，并且仅在2013年5月19日之前保证，不应在新应用程序中使用。

function findLocation() { 
    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('Location not found: ' + status); 
     } 
    }); 
    }

你可以尝试这样的...

<html> 
<head> 
    <title>Google Maps API Example: Simple Geocoding</title> 
<script src="http://maps.google.com/maps?file=api&amp;v=2&amp;key=ABQIAAAAjU0EJWnWPMv7oQ-jjS7dYxSPW5CJgpdgO_s4yyMovOaVh_KvvhSfpvagV18eOyDWu7VytS6Bi1CWxw" 
    type="text/javascript"></script> 
<script type="text/javascript"> 

var map = null; 
var geocoder = null; 

function initialize() { 
    if (GBrowserIsCompatible()) { 
    map = new GMap2(document.getElementById("map_canvas")); 
    map.setCenter(new GLatLng(17.445824,78.377395), 1); 
    map.setUIToDefault(); 
    geocoder = new GClientGeocoder(); 
    } 
} 

function showAddress(address) { 
    if (geocoder) { 
    geocoder.getLatLng(
     address, 
     function(point) { 
     if (!point) { 
      alert(address + " not found"); 
     } else { 
      map.setCenter(point, 15); 
      var marker = new GMarker(point, {draggable: true}); 
      map.addOverlay(marker); 
      GEvent.addListener(marker, "dragend", function() { 
      marker.openInfoWindowHtml(marker.getLatLng().toUrlValue(6)); 
      }); 
      GEvent.addListener(marker, "click", function() { 
      marker.openInfoWindowHtml(marker.getLatLng().toUrlValue(6)); 
      }); 
     GEvent.trigger(marker, "click"); 
     } 
     } 
    ); 
} 
} 
</script> 
</head> 

<body onload="initialize()" onunload="GUnload()"> 
<form action="#" onsubmit="showAddress(this.address.value); return false"> 

    <p> 
    <input type="text" style="width:350px" name="address" value="hitech city,   Hyderabad"/> 
    <input type="submit" value="Search" /> 
    </p> 
    <div id="map_canvas" style="width: 600px; height: 400px"></div> 
</form> 

</body> 
</html>

进行更改，因此..///

-1使用V2。 Maps API的[Version 2]（https://developers.google.com/maps/documentation/javascript/v2/reference）已弃用，并且仅在2013年5月19日之前有效。您应该使用[版本3]（https://developers.google.com/maps/documentation/javascript/reference） – 2013-02-11 20:40:20
