Google点击移动标记 [英] Google maps moving marker on click
问题描述
我想要做的是,在我的地图上,当我点击地图上的某处时,它显示了一个标记点,然后点击不同的点在地图上显示另一个标记。但我希望它将第一个标记移动到第二个点。
(为了将代码放在这里,我把它放在html标签后面。)
这是我的代码:
< html>
<样式类型=text / css>
#map_canvas {
height:760px;
width:1100px;
position:static;
top:100px;
left:200px;
}
< / style>
< script type =text / javascript
src =http:// maps。 google.com/maps/api/js?sensor=false\">
< / script>
< script type =text / javascript>
函数initialize(){
var latlng = new google.maps.LatLng(42.55308,9.140625);
var myOptions = {
zoom:2,
center:latlng,
mapTypeId:google.maps.MapTypeId.ROADMAP,
streetViewControl:false,
mapTypeControl:false,
};
var map = new google.maps.Map(document.getElementById(map_canvas),
myOptions);
google.maps.event.addListener(map,'click',function(event){
placeMarker(event.latLng);
});
函数placeMarker(location){
var marker = new google.maps.Marker({
position:location,
map:map
动画:google.maps.Animation.DROP,
});
map.setCenter(location);
}
}
< / script>
< / head>
< body onload =initialize()>
< div id =map_canvasstyle =1500px; 1000px>< / div>
< / body>
< / html>
每次 placemarker
已运行,它会创建一个新标记。
您需要在placemarker函数之外创建标记,然后在placemarker内部使用 marker.setPosition()
。
What I want to do is,
on my map, when I click somewhere on the map, it shows a marker on the point, then I click different point on the map then it shows a another marker. But I want it to move the first marker to the second point.
( I put " behind the html tags for putting the code here.)
This is my code:
<html>
<style type="text/css">
#map_canvas {
height: 760px;
width: 1100px;
position: static;
top: 100px;
left: 200px;
}
</style>
<script type="text/javascript"
src="http://maps.google.com/maps/api/js?sensor=false">
</script>
<script type="text/javascript">
function initialize() {
var latlng = new google.maps.LatLng(42.55308, 9.140625);
var myOptions = {
zoom: 2,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP,
streetViewControl: false,
mapTypeControl: false,
};
var map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
google.maps.event.addListener(map, 'click', function(event) {
placeMarker(event.latLng);
});
function placeMarker(location) {
var marker = new google.maps.Marker({
position: location,
map: map
animation: google.maps.Animation.DROP,
});
map.setCenter(location);
}
}
</script>
</head>
<body onload="initialize()">
<div id="map_canvas" style="1500px; 1000px"></div>
</body>
</html>
Every time placemarker()
is ran, it creates a new marker.
You need to create the marker once outside of the placemarker function and after that, inside placemarker, use marker.setPosition()
.
