Question

我使用Phonegap创建了一个简单的移动应用程序。它包含一个HTML页面，它在我的移动Android设备上完美打开，但是没有启用缩放。我试图添加几个库和元名称，但它似乎不起作用。

HTML页面显示带有标记的Google地图。这是完整的代码：

<!DOCTYPE html>
<html>
  <head>
    <title>Simple Map</title>
    <meta name="viewport" content="initial-scale=1.0, user-scalable=no">
    <meta charset="utf-8">
    <META HTTP-EQUIV="Refresh" CONTENT="420">
    <style type="text/css">
      html, body, #map-canvas {
        height: 100%;
        margin: 0px;
        padding: 0px
      }

       .labels {
     color: orange;
     background-color: black;
     font-family: "Lucida Grande", "Arial", sans-serif;
     font-size: 10px;
     font-weight: bold;
     text-align: center;
     width: 50px;     
     border: 2px solid black;
     white-space: nowrap;}
    </style>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
    <script src="https://jquery-xml2json-plugin.googlecode.com/svn/trunk/jquery.xml2json.js" type="text/javascript" language="javascript"></script>
    <script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
    <script src="http://google-maps-utility-library-v3.googlecode.com/svn/tags/markerwithlabel/1.0.1/src/markerwithlabel.js"></script>
    <script>
var markers = [];
var map = null;

  $.get('Customers.xml', function(xml) {
      var jsonObj = $.xml2json(xml);
        $.each(jsonObj.Marker, function(){
            var stat = this.site_status == "Critical" ? "http://maps.google.com/mapfiles/ms/micons/red-dot.png" : "http://maps.google.com/mapfiles/ms/micons/green-dot.png";
                 var mark = {
                        title: this.title,
                        location: this.site_location,
                        icon: stat
                        }
                markers.push(mark);
        });
        for(var i=0; i< markers.length; i++){
          var maddress = markers[i].location;
          var image = markers[i].icon;
          var custname = markers[i].title;
          geocodeAddress(maddress, image, custname,map); 
        } 
});     

function geocodeAddress(maddress, image, custname,map) {
  var geocoder = new google.maps.Geocoder();
  geocoder.geocode( { 'address': maddress}, function(results, status) { 
    if (status == google.maps.GeocoderStatus.OK) {   
      var myLatlng = new google.maps.LatLng(results[0].geometry.location.lat(),results[0].geometry.location.lng());
      var iconBase = 'https://maps.google.com/mapfiles/kml/shapes/';
      var marker = new MarkerWithLabel({
      position: myLatlng, map:map, icon: image,labelContent: custname,
       labelAnchor: new google.maps.Point(22, 0),
       labelClass: "labels", // the CSS class for the label
       labelStyle: {opacity: 0.75}});
    } else {
      alert("Geocode was not successful for the following reason: " + status);
    }
  });
}

function initialize() {
    var chicago = new google.maps.LatLng(35.442579,-40.895920);
    var mapOptions = {
        zoom: 4,
        center: chicago,
        mapTypeId: google.maps.MapTypeId.ROADMAP
  }

  map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
    </script>
  </head>
  <body>
     <div id="map-canvas"></div>
  </body>
</html>

为了启用“捏缩放”，我应该添加什么？提前谢谢。

Answer 1

要让pintch进行缩放，你必须使用“click”或“doubleclick”创建一个google.maps.event。您可以在您创建的标记或整个地图上附加此事件。告诉我你是否需要一些例子以及想要附加事件或搜索护目镜地图事件的内容。在线有100万个例子。

以下是Google地图网站的一个简单示例：Simple click event in google map

只需从html主题部分删除user-scalable=no

即可
