谷歌地图，设置最小和最大滑块控件 [英] Google maps, setting minimum and maximum slider controls

问题描述

我在googlemap上工作，这一切都很好，除了我似乎无法设置最大和最小缩放的事实（我想将级别限制为几个级别的任何一种默认缩放查看）

I am working on a googlemap, which all works fine, apart from the fact I can't seem to set a max and min zoom (I would like to limit the levels to a couple of levels either way of a default zoom view)

我尝试过使用map.getMimimumResolution，但是这似乎不工作 - 任何想法？

I have tried using the map.getMimimumResolution, but this doesn't seem to work - any ideas ?

function initialize() {   
   var latlng = new google.maps.LatLng("<%=Html.Encode(Model.Field01.Field01) %>", "<%=Html.Encode(Model.Field01.Field03) %>");
    var myOptions = {
    zoom: 13,
        center: latlng,
        disableDefaultUI: false,
        navigationControl: true,
        navigationControlOptions: {style: google.maps.NavigationControlStyle.ZOOM_PAN},
        navigationControl: true,
        mapTypeId: google.maps.MapTypeId.ROADMAP

    };
    var map = new google.maps.Map(document.getElementById("mapcontainer"), myOptions);

    map.getMinimumResolution = function() { return 6 }; 

    var marker = new google.maps.Marker({
        position: latlng,
        map: map,
        title: "<%=Model.AccomName %>"
      });
}

感谢您的任何想法，谢谢

Any thoughts appreciated, Thanks

推荐答案

getMinimumResolution是GMapType方法，而不是GMap2方法。所以不是这样的：

getMinimumResolution is a GMapType Method, not a GMap2 Method. so instead of this:

map.getMinimumResolution = function() { return 6 };

您可以这样做：

You could do this:

var mt = map.getMapTypes();

for (var i=0; i<mt.length; i++) {
  mt[i].getMinimumResolution = function() {return 6;}
}
