If you need latitude and longitude of a given adress, you can use google maps api https://developers.google.com/maps/documentation/javascript/
如果您需要给定地址的纬度和经度，您可以使用谷歌地图 API https://developers.google.com/maps/documentation/javascript/
Here is an example: https://google-developers.appspot.com/maps/documentation/javascript/examples/geocoding-simple

EDIT: to display it in an alert popup:
编辑：在警报弹出窗口中显示它：
var address = document.getElementById("address").value;
var geocoder = new google.maps.Geocoder();
geocoder.geocode( { 'address': address}, function(results, status) {
var location = results[0].geometry.location;
alert(location.lat() + '' + location.lng());
});
