Question

此地图工作正常，但问题是地图未显示地图指针，因为地图正在显示以便于定位。如何在地图上添加谷歌地图点，以便轻松跟踪位置。

google开发者网站上的页面谈论了所有相关内容：

https://developers.google.com/maps/documentation/javascript/examples/marker-simple

function initialize() {
var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
var mapOptions = {
zoom: 4,
center: myLatlng
}
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);

var marker = new google.maps.Marker({
  position: myLatlng,
  map: map,
  title: 'Hello World!'
});
}

在地图中使用此脚本以及脚本：

google.maps.event.addDomListener(window, 'load', initialize);
