如何通过点击按钮来更改Google地图中心 [英] How to change Google Map Center by clicking a button
问题描述
我使用Google Map API v3和jQuery 1.11.0。
我在以下div中使用Google Map -
< div id =googleMapclass =map_div>< / div>
map.js 位于HTML文件外部,它已链接。 / p>
现在我在html( outside map )的另一部分中有一个按钮 -
< button id =3>更改中心< /按钮>
现在我想添加一个点击事件,它会将地图的中心更改为新的纬度, Lon。
所以,我在HTML中使用JavaScript这样 -
<脚本>
$(document).ready(function()
{
$(#3)。click(function(){
var center = new google.maps.LatLng (10.23,123.45);
map.panTo(center);
});
});
< / script>
任何人都可以帮我吗?

I am using Google Map API v3 and jQuery 1.11.0.
I have a Google Map in the following div-
<div id="googleMap" class="map_div"></div>
The map.js is outside html file, it is linked.
Now I have a button in another part of the html (outside map) like this-
<button id="3">Change center</button>
Now I want to add a on click event which will Change the center of the map to new Lat,Lon.
So, I have JavaScript in HTML like this-
<script>
$(document).ready(function()
{
$("#3").click(function(){
var center = new google.maps.LatLng(10.23,123.45);
map.panTo(center);
});
});
</script>
Can anyone help me please?
