问题描述
我一直在使用PhoneGap的创建了一个简单的移动应用。
它包含一个HTML页面，它完美地打开我的手机在Android设备上，但捏变焦未启用。
我尝试添加几个库和元的名字，但它似乎并没有工作。

中的HTML页面显示谷歌地图与标记。
下面是完整的code：
The HTML page displays a Google Map with markers.Here is the complete code:

});
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) {

var marker = new MarkerWithLabel({

} 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>
我应该补充，以使捏放大？
先谢谢了。
What should I add in order to enable 'pinch to zoom' ?Thanks in advance.
推荐答案
有pintch放大，你必须创建一个点击和双击一个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，如果你需要一些例子，并要附加您的活动或搜索护目镜地图的事件是什么。有例子字面上百万在线。
to have pintch to zoom you have to create a google.maps.event with "click" or "doubleclick". you can attach this event on marker you created or on entire map. tell me if you need some example and to what you want to attach your event or search for goggle map events. there are literally 1000000 of examples online.
下面是谷歌地图的网站一个简单的例子：
Here is a simple example from google map site: Simple click event in google map
