Latitude, Longitude Grabber
提问by Mat B.
What I would like to do is create app where when anyone clicks on the map object and two fields get filled with latitude and longitude at every click. Is there sample code of Google Maps V3 JavaScript API (Geocoding API) somewhere out there that does something like that?
我想做的是创建应用程序，当任何人单击地图对象时，每次单击时两个字段都会填充纬度和经度。是否有 Google Maps V3 JavaScript API（地理编码 API）的示例代码可以做类似的事情？

You can achieve this with google.maps.event'LatLng property:
您可以使用google.maps.event'LatLng 属性实现此目的：
Something like this would show how it works. Here is a JSFiddle Demo:
像这样的东西会显示它是如何工作的。这是一个JSFiddle 演示：
google.maps.event.addListener(map, 'click', function(event){
alert('Lat: ' + event.latLng.lat() + ' Lng: ' + event.latLng.lng());
});
Where map is your google map object. Yes the example is in V2 i think, and if you would like to create a marker on click you can simply create it within the click callback function.
其中 map 是您的 google map 对象。是的，我认为这个例子在 V2 中，如果你想在点击时创建一个标记，你可以简单地在点击回调函数中创建它。

这是第 2 版的完整代码，我已经使用了很长时间，并且已在网站上发布。
just click view source code from your browser and copy save the contents. it will work perfectly. only thing is you need to change the map api key.
只需单击浏览器中的查看源代码并复制保存内容。它会完美地工作。唯一的问题是您需要更改地图 api 密钥。

function onload()
{
var map= new google.maps.Map(document.getElementById('map'), {
center: new google.maps.LatLng(37.4419, -122.1419),
zoom: 14,
mapTypeId: google.maps.MapTypeId.ROADMAP,
disableDefaultUI: true
});
google.maps.event.addListener(map, 'click', function(event){
alert('Lat: ' + event.latLng.lat() + ' and Longitude is: ' + event.latLng.lng());
}
After loading code you can write this code to get latitude and longitude of fix points. please try
加载代码后，您可以编写此代码来获取固定点的纬度和经度。请试试

var map = [google map];
google.maps.event.addListener(map, 'click', function (mouseEvent) {
alert(mouseEvent.latLng.toUrlValue());
});
