本文关键字：-Firefox 触摸 新标记 创建 Php 并在 显示 代码 位置 谷歌地图      更新时间：2023-09-26

我正试图让我的代码在当前位置显示一个标记，并在触摸或点击屏幕时设置一个新的标记，这就是我迄今为止所拥有的，因为我不是程序员，所以我在这个网站上创建的大部分代码都是为了工作。

您必须给当前位置对象初始化函数，才能获得当前位置

  function initialize(curr_position) {
      var map_center = new google.maps.LatLng(curr_position.coords.latitude, curr_position.coords.longitude);
    var mapOptions = {
      zoom: 14,
      center: map_center,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    }  
    map = new google.maps.Map(document.getElementById('map_canvas'), 
        mapOptions);    
    var lavaditozone = [
        {lat: 20.59093056, lng: -100.433975},
        {lat: 20.57652778, lng: -100.433975},
        {lat: 20.57652778, lng: -100.40218611},
        {lat: 20.58610278, lng: -100.4120722},
        {lat: 20.59093056, lng: -100.433975}
    ];
   var arealavadito = new google.maps.Polyline({
       path: lavaditozone ,
       strokeColor: '#FF0000',
       strokeOpacity: 1,
       strokeWeight: 10
    });
    arealavadito.setMap(map);
    google.maps.event.addListener(map, 'click', function(event){
        addMarker(event.latLng);
    });    
  }
