Question

我正在尝试使用以下脚本生成相同分区和相同变量“ map ”的地图onclick，它不起作用，我不知道如何破坏旧地图并重新创建请有人帮助我..这是我到目前为止所尝试的......

以下是 fiddle的链接

JS

function map(lat,lon){
  jQuery(document).ready(function () {
  var centerPosition = new google.maps.LatLng(lat, lon);
  var options = {
    zoom: 16,
    center: centerPosition,
    mapTypeId: google.maps.MapTypeId.ROADMAP
   };
    var map = new google.maps.Map(document.getElementById("map"), options);
  });
 }

var lat =22, lon = 75;
map(lat,lon);

HTML

   <div id="map"></div>
   <button onclick="map(15,90)" >15 90</button>
   <button onclick="map(22,80)" >22 80</button>

CSS

#map {
 height: 300px;
 width: 500px;
}
button{ width:70px;height:40px;}

Answer 1

function map(lat,lon){
  // jQuery(document).ready(function () {
  var centerPosition = new google.maps.LatLng(lat, lon);
  var options = {
    zoom: 16,
    center: centerPosition,
    mapTypeId: google.maps.MapTypeId.ROADMAP
   };
  var map = new google.maps.Map(document.getElementById("map"), options);
  //});
}

我没有对它进行测试，只需查看语法

即可
