我已经在数据库顶部建立连接,并以关联数组
获取记录<? php include_once('dbconnect.php');
$sql = "SELECT * FROM maps";
$result = mysql_query($sql);
while ($row = mysql_fetch_assoc($result)) {
$arr[] = $row;
}
?>
我的底部有一个脚本,但下面是</body>
标记:
<script>
function initialize(){
var map;
var locations = <?php echo json_encode($arr); ?>;
var strfy=JSON.stringify(locations);
var location=JSON.parse(locations);
var mapoption={
zoom: 10,
center: new google.maps.LatLng(-33.92, 151.25),
mapTypeId: google.maps.MapTypeId.SATELLITE
};
map = new google.maps.Map(document.getElementById('map'), mapoption);
var infowindow= new google.maps.InfoWindow();
var marker,i;
for(i=0;i<location.length;i++){
marker = new google.maps.Marker({
position: new google.maps.LatLng(location.query.lat,location.query.longits),
map: map
});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(location.name);
infowindow.open(map, marker);
}
})(marker, i));
}
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
我身体部位在中间
<div id="map" style="width:100%;height:380px;"></div>
记录已在关联数组中成功获取,但我遇到了问题。当我运行localhost时,它不会向我显示googlemap但会显示错误
是什么导致了这个问题?

添加google maps api时,请检查您是否明确设置了协议。 对于localhost,它应该以http://或https://开头。它会告诉浏览器从Web加载库而不是文件系统。

似乎var位置是一个全局变量 - window.location,因此当您尝试分配值时,浏览器会重定向,只需重命名,或执行类似的操作
(函数(){ YOUR_CODE_HERE })();
用于封装
你需要这样的想法:
function initialize() {
var map;
var locations = <? php echo json_encode($arr); ?> ;// $arr must be not an associative array
//2 next strings doesn't metter
//var strfy = JSON.stringify(locations);
//var location = JSON.parse(strfy);
alert(locations);
var mapoption = {
zoom: 10,
center: new google.maps.LatLng(-33.92, 151.25),
mapTypeId: google.maps.MapTypeId.SATELLITE
};
map = new google.maps.Map(document.getElementById('map'), mapoption);
var infowindow = new google.maps.InfoWindow();
var marker;
for (var i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i].lat, locations[i].longits),
map: map
});
google.maps.event.addListener(marker, 'click', (function (marker, i) {
return function () {
infowindow.setContent(locations[i].name);
infowindow.open(map, marker);
}
})(marker, i));
}
}
google.maps.event.addDomListener(window, 'load', initialize);
