我想在我的地图中实现这个Location Search插件。它根本不工作,但控制台日志没有任何错误。你可以帮我解决这个问题吗,不幸的是我不是Javascript专家。
谢谢!
我的代码:
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&libraries=places"></script>
<input type="text" value="" id="searchbox" style=" width:800px;height:30px; font-size:15px;">
<div id="map-canvas" style="width:100%; height:650px; margin:0 auto;"></div>
<script>
var map = null;
function initialize()
{
var mapOptions =
{
zoom: 8,
center:new google.maps.LatLng(47.165843,18.9483089)
};
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
loadXMLFile();
var geocoder = new google.maps.Geocoder();
jQuery(function() {
jQuery("#searchbox").autocomplete({
source: function(request, response) {
if (geocoder == null){
geocoder = new google.maps.Geocoder();
}
geocoder.geocode( {'address': request.term }, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var searchLoc = results[0].geometry.location;
var lat = results[0].geometry.location.lat();
var lng = results[0].geometry.location.lng();
var latlng = new google.maps.LatLng(lat, lng);
var bounds = results[0].geometry.bounds;
geocoder.geocode({'latLng': latlng}, function(results1, status1) {
if (status1 == google.maps.GeocoderStatus.OK) {
if (results1[1]) {
response(jQuery.map(results1, function(loc) {
return {
label : loc.formatted_address,
value : loc.formatted_address,
bounds : loc.geometry.bounds
}
}));
}
}
});
}
});
},
select: function(event,ui){
var pos = ui.item.position;
var lct = ui.item.locType;
var bounds = ui.item.bounds;
if (bounds){
map.fitBounds(bounds);
}
}
});
});
}
function loadXMLFile(){
var filename = '<?php echo get_template_directory_uri(); ?>/scripts/mylist.xml.cache';
jQuery.ajax({

function onXMLLoadFailed(){

jQuery.ajax({ url: '<?php echo get_template_directory_uri(); ?>/scripts/getxml.php',

var lng = jQuery(this).find('Lng').text();
var markerCoords = new google.maps.LatLng(lat.replace(',', '.'),lng.replace(',', '.'));
var image = {

size: new google.maps.Size(36, 24),
origin: new google.maps.Point(0, 0),

var infowindow = new google.maps.InfoWindow({

var marker = new google.maps.Marker({

您正在查看的示例是使用旧版Google Maps API完成的。当前版本有一个自动完成小部件,可以处理您的用例。只需做
var input = document.getElementById('searchbox');
var autocomplete = new google.maps.places.Autocomplete(input);
每当一个人选择一个建议的位置时,将触发place_changed
事件,因此您可以设置一个侦听器来检测此类事件并处理该地点:
google.maps.event.addListener(autocomplete, 'place_changed', function () {
var place = autocomplete.getPlace();
console.log('place changed', place);
});
根据您获得的地点类型,您应该选择何时最好将地图置于给定点上,或者将地图边界拟合到某个边界框上。
