Google Maps API V3和本地搜索问题 - 空白结果？ [英] Google Maps API V3 and Local search problem - empty results?
问题描述
我正在尝试实施Maps API V3和本地搜索，但我似乎遇到了问题。不知何故， OnLocalSearch（）函数中的结果是空的。
I am trying to implement a Maps API V3 and Local Search but I seem to be having problems. Somehow, the results in the OnLocalSearch() function is empty.
以下是我的完整代码：
Here is my complete code:
<script type="text/javascript">
//<![CDATA[
$(document).ready(function() {
// do stuff when DOM is ready
var geocoder = new google.maps.Geocoder();
var address = '{{string_location}}';
var map;
// Our global state for LocalSearch
var gInfoWindow;
var gSelectedResults = [];
var gCurrentResults = [];
var gLocalSearch = new GlocalSearch();
if (geocoder) {
geocoder.geocode({ 'address': address }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
//alert(results[0].geometry.location.lat())
//alert(results[0].geometry.location.lng())
//Create the Map and center to geocode results latlong
var latlng = new google.maps.LatLng(results[0].geometry.location.lat(), results[0].geometry.location.lng());
var myOptions = {
zoom: 14,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
gLocalSearch.setSearchCompleteCallback(this, OnLocalSearch);
gLocalSearch.execute("{{business_item.name}}");
}
else {
alert('No results found. Check console.log()');
console.log("Geocoding address: " + address);
console.log("Geocoding failed: " + status);
}
});
}
/*
Other functions
*/
function OnLocalSearch() {
if (gLocalSearch.results[0]) { //This is empty. Why?
var resultLat = gLocalSearch.results[0].lat;
var resultLng = gLocalSearch.results[0].lng;
var point = new GLatLng(resultLat,resultLng);
callbackFunction(point);
}else{
alert("not found!");
}
}
});
//]]>
</script>
仅供参考，我以此为例，现在我坚持了几个小时： http：// gmaps-samples-v3。 googlecode.com/svn-history/r136/trunk/localsearch/places.html
FYI, I am using this as an example and I am stuck for a few hours now about this: http://gmaps-samples-v3.googlecode.com/svn-history/r136/trunk/localsearch/places.html
任何回复将不胜感激。
问候，

更新我在这里犯了一个错误：
UPDATE I made a mistake somewhere here:
<script src="http://www.google.com/uds/api?file=uds.js&v=1.0" type="text/javascript"><;/script>
<script src="http://maps.google.com/maps/api/js?v=3.1&sensor=false®ion=PH"></script>
另外，请确保您仔细检查您正在进行地理编码的地址。我来自菲律宾，Google似乎只对主要道路进行地理编码。请参阅 http://gmaps-samples.googlecode.com/svn/trunk/mapcoverage_filtered .html
Also, make sure you double check the address you are geocoding. I am from the Philippines and it seems that Google only geocodes Major Roads. See http://gmaps-samples.googlecode.com/svn/trunk/mapcoverage_filtered.html

推荐答案
只需进行一些调整，以便代码实际完成，并且使用我知道的地址将成功进行地址解析，再加上我知道的查询将返回一些内容，您的代码就可以正常工作。以下是我所做的：
Just making a couple of tweaks so that the code is actually complete, and using an address I know will be geocoded successfully plus a query I know will return something, your code works. Here is what I did:

<script type="text/javascript">
//<![CDATA[
google.load('jquery','1.4.2');

$(document).ready(function() {
alert('here');
// do stuff when DOM is ready
var geocoder = new google.maps.Geocoder();
var address = '4019 lower beaver rd. 50310';
var map;
// Our global state for LocalSearch
var gInfoWindow;
var gSelectedResults = [];
var gCurrentResults = [];
var gLocalSearch = new GlocalSearch();
if (geocoder) {
geocoder.geocode({ 'address': address }, function (results, status) {
