此代码必须使用 google map API 初始化标记。但是当我尝试在浏览器中打开它时,页面变成白色(不起作用)。我无法理解这个问题...我的所有资源都已连接。

Map.jsp:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>dsf</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
</head>
<body>
<script type="text/javascript">
$.ajax({
type: "POST",
url: "http://localhost:1600/jsp/datasend.jsp",
data: "",
async: false,
success: function(msg){
window.obj = $.parseJSON(msg);
}
});
</script>
<div id="map"></div>
<script>
var marks = [];
window.total_count = obj.length;
for(var i=0; i<total_count; i++){
marks[i] = [Number(obj[i]['gps'][0]),Number(obj[i]['gps'][1])];
}
function initMap() {
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 10,
center: {lat: marks[0][0], lng:marks[0][1]}
});
setMarkers(map);
}
//alert(total_count);
function setMarkers(map) {
for(var i=0; i<total_count; i++){
var image = 'http://localhost:1601/graphic/marker.svg'; //+ obj[i]['marker'] + '.svg';
var marker = new google.maps.Marker({
position: {lat: marks[i][0], lng: marks[i][1]},
map: map,
icon: image
});
}
}
</script>
<script async true src="https://maps.googleapis.com/maps/api/js?key=AIzaSyDxJe0GV6Oquvs4I8yZpEQdC7BZ-X5YXCs&signed_in=true&callback=initMap"></script>
</body>
</html>

数据发送的响应如下所示 {"data":{"id":[ 1 ]}{"latitude":[ 56.55557 ]}{"longitude":[ 53.678789 ]}{"distancefortb":[ d]}}

我的代码有什么问题吗?

最佳答案

我创建了一个sample用一个标记(印度那格浦尔)。希望这段代码会有帮助。

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8" />
<title>Google Maps Markers</title>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&libraries=places"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script type="text/javascript">

var map;
// Creates the map
function initialize() {
map = new google.maps.Map(document.getElementById('map'), {
zoom: 10,
center: new google.maps.LatLng(21.1458004, 79.0881546), //For Nagpur
mapTypeId: google.maps.MapTypeId.ROADMAP
});
}

// This function takes an array argument containing a list of marker data
function generateMarkers(locations) {
for (var i = 0; i < locations.length; i++) {
new google.maps.Marker({
position: new google.maps.LatLng(21.1011957, 79.1026544),
map: map,
title: locations[i][0]
});
}
}
</script>
</head>
<body>
<div id="map" style="width: 500px; height: 400px;"></div>
<script type="text/javascript">

window.onload = function () {
initialize();
var loc2 = [];
// I have created by getting the city and country. Then find Latitude and Longitude.
var address = 'Nagpur,India';
geocoder = new google.maps.Geocoder();
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
loc2.push("['Nagpur'," + 21.2333 + "," + 79.2000 +"]");
locations1 = "[" + loc2 + "]";
generateMarkers(eval(locations1));
}
else {
alert("Geocode was not successful for the following reason: " + status);
}
});
};
</script>
</body>
</html>

此代码将启动带有标记(那格浦尔-印度)的 map 。同样,您可以根据您的需要进行定制。希望这会有所帮助。
