jquery-ui-map設置縮放級別

Question

我有以下代碼如何映射。一切工作正常，除了縮放參數。無論我爲縮放設置什麼，它總是顯示相同的縮放級別。我能做什麼？

$('#pagemap').live("pageshow", function() { 

      $('#map_canvas').gmap().bind('init', function(evt, map) { 

       $('#map_canvas').gmap('getCurrentPosition', function(position, status) { 

         if (status === 'OK') { 

          var clientPosition = new google.maps.LatLng(position.coords.latitude, position.coords.longitude); 

          $('#map_canvas').gmap('option', 'mapTypeId', google.maps.MapTypeId.SATELLITE); 

          $('#map_canvas').gmap('option', 'zoom', 13);    

          $('#map_canvas').gmap('addMarker', {'position': clientPosition, 'bounds': true}); 

         } 
       }); 
      }); 
     }); 

Answer 1

您需要將標記的'bounds'選項更改爲false。

$('#map_canvas').gmap('addMarker', {'position': clientPosition, 'bounds': false});

如果設置該屬性範圍爲true，地圖將計算視窗，並自動變焦，覆蓋任何變焦集的構造器 大段引用

Answer 2

我正面臨着該解決方案的問題。如果我將邊界設置爲false，則地圖保持居中於其初始中心座標。好吧。那麼爲什麼我的地圖集中在一個很遠的地方？好的，沒問題。但是如果我仍然想在添加標記後設置特定的縮放級別？

$("your-selector").gmap('addMarker', { 
    'position': latlng, 
    'bounds': true 
}, function(map, marker) { 
    map.set('zoom', 12); 
}).click(function() { 
    $(this.container).gmap('openInfoWindow', { 'content': 'TEXT_AND_HTML_IN_INFOWINDOW' }, this); 
}); 

你只是回調gmap函數。但是，人們是不是應該糾正這個插件API文檔中的所有斷開鏈接？是不是應該爲任何插件編寫精心指定和清晰的Javascript文檔？讓我們互相幫助，這種方式非常複雜。我們失去了很多時間。

試試這個，看看這個 「縮放：9」 在縮放級別代碼...
