任何人给我解决方案如何将$ location变量放到jscript以获取谷歌地图上的位置。什么应该是位置的价值（位置名称或邮政编码）。这是代码：
<?php
$location=$_GET["clocation"]; //fetched clocation from database in previous page
?>
<div id="map" style="width:100%;height:500px"></div>
<script>
function myMap() {
var myCenter = new google.maps.LatLng(23.6943,90.3444); //Here i want to put my location value to get location on google map
var mapCanvas = document.getElementById("map");
var mapOptions = {center: myCenter, zoom: 7, panControl: true,
zoomControl: true,
mapTypeControl: true,
scaleControl: true,
streetViewControl: true,
overviewMapControl: true,
rotateControl: true };
var map = new google.maps.Map(mapCanvas, mapOptions);
var marker = new google.maps.Marker({position:myCenter});
marker.setMap(map);
}
</script>
<script src="https://maps.googleapis.com/maps/api/js?key=<hidden>&callback=myMap"></script>
假设您的位置格式正确（lat，lng）， 您可以在脚本中执行此操作：
<?php
$location=$_GET["clocation"]; //fetched clocation from database in previous page
?>
…
var myCenter = new google.maps.LatLng(<?php echo $location ?>); //Here we simply echo the $location
…
编辑：我看到您使用“（位置名称或邮政编码）”编辑了您的帖子。
Google Maps API提供了一种地理编码服务，可用于将您的地址转换为lat，lng格式。
以下是地理编码文档的链接： https://developers.google.com/maps/documentation/javascript/geocoding
而且，这里回答了类似的问题： Using Address Instead Of Longitude And Latitude With Google Maps API
假设clocation的值是一个城市（感谢添加该细节），您需要使用GeoCoder服务将地址转换为latLng，然后您可以使用该地址在该位置添加标记。
<?php
$location=isset( $_GET["clocation"] ) ? $_GET["clocation"] : 'London';
?>
<html>
<head>
<script>
function myMap() {
<?php
echo "
var address='$location';
";
?>
var geocoder = new google.maps.Geocoder();
var infoWindow = new google.maps.InfoWindow();
var myCenter = new google.maps.LatLng( 23.6943, 90.3444 );
var mapCanvas = document.getElementById("map");
var mapOptions = {
center: myCenter,
zoom: 7,
panControl: true,
zoomControl: true,
mapTypeControl: true,
scaleControl: true,
streetViewControl: true,
overviewMapControl: true,
rotateControl: true
};
var map = new google.maps.Map( mapCanvas, mapOptions );
var marker = new google.maps.Marker( { position:myCenter } );
marker.setMap( map );
/* a callback function to process the response from geocoding */
var evtcallback=function(results, status){
if( status == google.maps.GeocoderStatus.OK ){
var _address=results[0].formatted_address;
var _location=results[0].geometry.location;
var _lat=_location.lat();
var _lng=_location.lng();
console.info( 'Geocoding succeeded for %s and found address %s [ %s,%s ]', address, _address, _lat, _lng );
latlng=new google.maps.LatLng( _lat, _lng );
marker.setPosition( latlng );
marker.setTitle( _address );
google.maps.event.addListener( marker, 'click', function(event){
infoWindow.setContent( this.title );
infoWindow.open( map, this );
infoWindow.setPosition( this.position );
}.bind( marker ) );
map.setCenter( latlng );
map.setZoom(15);
} else {
console.info('geocoding %s failed with status %d', address, status);
}
}
/* invoke the geocoder service with your location to geocode */
geocoder.geocode({ 'address':address }, evtcallback );
}
