我在 Google map 中有一个可拖动的标记。我想将标记的位置发送到 Flask View 。我该怎么做？
<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>
<body onload='initialize()'>
Lat:
<input id="lat" name="lat" val="40.713956" />
Long:
<input id="long" name="long" val="74.006653" />
<div id="map_canvas" style="width: 500px; height: 250px;"></div>
<script>
var map;
function initialize() {
var myLatlng = new google.maps.LatLng({{ lat}}, {{ long }});
var myOptions = {
zoom: 8,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var marker = new google.maps.Marker({
draggable: true,
position: myLatlng,
map: map,
title: "Your location"
});
google.maps.event.addListener(marker, 'dragend', function (event) {
document.getElementById("lat").value = event.latLng.lat();
document.getElementById("long").value = event.latLng.lng();
});
// close popup window
google.maps.event.addListener(map, 'click', function() {
infowindow.close();
});
}
google.maps.event.addDomListener(window, "load", initialize());
</script>
</body>
最佳答案
在一位优秀的开发人员的帮助下，我自己找到了它。
JavaScript:
function initialize() {
var myLatlng = new google.maps.LatLng({{ geolat }}, {{ geolong }});
var myOptions = {
zoom: 16,
center: myLatlng,
streetViewControl: true,
mapTypeControl: true,
zoomControl: true,
mapTypeId: google.maps.MapTypeId.SATELLITE
};
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var marker = new google.maps.Marker({
draggable: true,
position: myLatlng,
map: map,
title: "Your location"
});
google.maps.event.addListener(marker, 'dragend', function (event) {
sendCoords(event.latLng.lat(),event.latLng.lng() )
});
// close popup window
google.maps.event.addListener(map, 'click', function() {
infowindow.close();
});
在您的 .py 脚本中创建获取参数，如下所示:
lat = request.args.get('lat')
long = request.args.get('long')
并存储变量(或任何你需要的)
