谷歌地图泛地 [英] google maps pan to
问题描述
一整天都在努力,通过文字链接在谷歌地图中设置一个平底锅。它看起来像地图本身的id没有被传递给函数,但我已经尝试了许多没有喜悦的事情。
< script type =text / javascript>
var home = new google.maps.LatLng(4.915833,10.195313);
函数initialize(){
var myOptions = {
zoom:2,
center:home,
mapTypeId:google.maps.MapTypeId.ROADMAP,
mapTypeControl:false,
panControl:true,
panControlOptions:{
position:google.maps.ControlPosition.LEFT_CENTER
},
zoomControl:true,
zoomControlOptions:{
style:google.maps.ZoomControlStyle.LARGE,
position:google.maps.ControlPosition.LEFT_CENTER
},
scaleControl:false,
streetViewControl :true,
streetViewControlOptions:{
position:google.maps.ControlPosition.LEFT_CENTER
}
}
var map = new google.maps.Map(document.getElementById (map),myOptions);
setMarkers(地图,目的地);
clickroute(map);
}
var destinations = [
['Marbella',36.509937,-4.886352],
['Algarve',37.016945,-7.928728],
['London ',51.508129,-0.128005],
['Istanbul',41.00527,28.97696],
['Whistler',50.116168,-122.959423]
];
function setMarkers(map,locations){
var image = new google.maps.MarkerImage('img / marker.png',
google.maps.Size(41,63),
new google.maps.Point(0,0));
for(var i = 0; i< locations.length; i ++){
var destination = locations [i];
var myLatLng = new google.maps.LatLng(destination [1],destination [2]);
var marker = new google.maps.Marker({
position:myLatLng,
map:map,
icon:image,
title:destination [0]
});
}
}
函数clickroute(lati,long){
var latLng = new google.maps.LatLng(51.433373,-0.712251);
map.panTo(latLng);
}
< / script>
< li onclick =clickroute()>测试< / li>
有什么可能导致问题的想法?我收到了一个js错误:
Uncaught TypeError:Object#< HTMLDivElement>没有方法'panTo'
谢谢

@onemach是正确的。
您必须在javascript的开头声明 map
作为全局变量。只需在< script type =text / javascript>
标签后立即执行 var map;
声明
2。
同时你的地图初始化应该改为
map = new google.maps.Map(document .getElementById(map),myOptions); //没有'var'
<3>您的电话 clickroute()
onClick < li>
不带参数。所以改变 clickroute()
的定义是这样的:
function clickroute (){//只是省略'lati'和'long'
var latLng = new google.maps.LatLng(51.433373,-0.712251);
map.panTo(latLng);
}
现在点击 test
< li>
您的地图将移动到点(51.433373,-0.712251)
Been struggling all day with setting a pan to in google maps from a text link. It looks like the id of the map itself isnt being passed through to the function but I have tried a number of things with no joy.
<script type="text/javascript">
var home = new google.maps.LatLng(4.915833, 10.195313);
function initialize() {
var myOptions = {
zoom: 2,
center: home,
mapTypeId: google.maps.MapTypeId.ROADMAP,
mapTypeControl: false,
panControl: true,
panControlOptions: {
position: google.maps.ControlPosition.LEFT_CENTER
},
zoomControl: true,
zoomControlOptions: {
style: google.maps.ZoomControlStyle.LARGE,
position: google.maps.ControlPosition.LEFT_CENTER
},
scaleControl: false,
streetViewControl: true,
streetViewControlOptions: {
position: google.maps.ControlPosition.LEFT_CENTER
}
}
var map = new google.maps.Map(document.getElementById("map"), myOptions);
setMarkers(map, destinations);
clickroute(map);
}
var destinations = [
['Marbella', 36.509937, -4.886352],
['Algarve', 37.016945, -7.928728],
['London', 51.508129, -0.128005],
['Istanbul', 41.00527, 28.97696],
['Whistler', 50.116168, -122.959423]
];
function setMarkers(map, locations) {
var image = new google.maps.MarkerImage('img/marker.png',
new google.maps.Size(41, 63),
new google.maps.Point(0,0));
for (var i = 0; i < locations.length; i++) {
var destination = locations[i];
var myLatLng = new google.maps.LatLng(destination[1], destination[2]);
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
icon: image,
title: destination[0]
});
}
}
function clickroute(lati, long) {
var latLng = new google.maps.LatLng(51.433373, -0.712251);
map.panTo(latLng);
}
</script>
<li onclick="clickroute()">test</li>
Any possible ideas on what could cause the issue? I get a js error with
Uncaught TypeError: Object #<HTMLDivElement> has no method 'panTo'
Thanks

@onemach is correct.
1.
You have to declare the map
as a global variable at the beginning of javascript. Just do a var map;
declaration immediately after <script type="text/javascript">
tag.
2. And at the same time your map initialization should be changed to
map = new google.maps.Map(document.getElementById("map"), myOptions); // without the 'var'
3. Your calling clickroute()
onClick of <li>
without parameters. So change the definition of clickroute()
like this :
function clickroute() { //just omit the 'lati' and 'long'
var latLng = new google.maps.LatLng(51.433373, -0.712251);
map.panTo(latLng);
}
Now clicking on the test
<li>
your map will move to point (51.433373, -0.712251)
