javascript - 谷歌地图显示 BAD

Question

大家好，我有一个应用程序和一个表单，我要求用户在其中输入地址，并在文本字段下方显示带有标记的谷歌地图，用户可以在其中将标记拖/放到正确的位置。问题是，在显示 map 的开始时，它只是部分显示而不是全部，而当我调整窗口大小时， map 显示正确。以下是我得到的图片:

我打开表格时的第一张照片(坏的):

然后在我调整窗口大小后(好一个)

有人知道如何解决这个问题吗？？？我真的很想知道它。

以防万一你想知道我显示 map 的代码是这样的:

  <div id="address">
    <table>     
        <tr>
              <td align="left" style="width:100%">
              <input type="text" id="addresspicker_map">
              </td>
        </tr>               
        <tr>
              <td style="width:100%">
                <div id="map"></div>
                <div id="legend">You can drag and drop the marker to the correct location</div>
              </td>
        </tr>                                         
   </table>                                 
</div>

编辑:

map 的 CSS 是这样的:

.ui-menu .ui-menu-item a {font-size: 12px;}
/* Layout helpers
----------------------------------*/
.ui-helper-hidden { display: block; }
.ui-helper-hidden-accessible { position: absolute !important; clip: rect(1px 1px 1px 1px); clip: rect(1px,1px,1px,1px); }
.ui-helper-reset { margin: 0; padding: 0; border: 0; outline: 0; line-height: 1.3; text-decoration: none; font-size: 100%; list-style: none; }

/* workarounds */
* html .ui-autocomplete { width:1px; } /* without this, the menu expands to 100% in IE6 */
.ui-menu {list-style:none;padding: 2px;margin: 0;display:block;float: left;}
.ui-menu .ui-menu {margin-top: 0px;}
.ui-menu .ui-menu-item {width: 100%;}
.ui-menu .ui-menu-item a {text-decoration:none;display:block;padding:.2em;}

/* Component containers
----------------------------------*/
.ui-widget { font-family: Verdana,Arial,sans-serif; font-size: 100%; }
.ui-widget-content { border: 2px solid rgba(0,143,15,0.3); background: #ffffff; color: #222222; }

/* Interaction states
----------------------------------*/
.ui-state-hover, .ui-widget-content .ui-state-hover, .ui-widget-header .ui-state-hover, .ui-state-focus, .ui-widget-content .ui-state-focus, .ui-widget-header .ui-state-focus { border: 1px solid #ffffff; background: #dadada; font-weight: normal; color: #212121; }

#map {border: 5px solid #DDD; width:95%;  height: 400px;  margin: 10px 0 10px 0;  -webkit-box-shadow: #AAA 0px 0px 15px;}

和 jQuery 1.10.2

和

echo $this->Html->script('jquery-1.10.2.js');
  //THESE ARE JUST FOR GOOGLE MAPS API
  echo $this->Html->script('http://maps.googleapis.com/maps/api/js?sensor=false');
  echo $this->Html->script('http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js');

    }
  });

  $.extend( $.ui.addresspicker, {
    version: "@VERSION"
  });

  // make IE think it doesn't suck
  if(!Array.indexOf){
    Array.prototype.indexOf = function(obj){
      for(var i=0; i<this.length; i++){
        if(this[i]==obj){
          return i;
        }
      }
      return -1;
    }
  }

})( jQuery );

这就是我初始化 map 的方式

    <script>
  $(function() {
    var addresspicker = $( "#addresspicker" ).addresspicker({
      componentsFilter: 'country:IT'
    });
    var addresspickerMap = $( "#addresspicker_map" ).addresspicker({
      regionBias: "it",
      updateCallback: showCallback,
      mapOptions: {
        zoom: 4,
        center: new google.maps.LatLng(46, 2),
        scrollwheel: true, // if false means u can zoom only with the +, - sign
        mapTypeId: google.maps.MapTypeId.ROADMAP
      },
      elements: {
        map:      "#map",
        lat:      "#lat",
        lng:      "#lng",
        street_number: '#street_number',
        route: '#route',
        locality: '#locality',
        administrative_area_level_2: '#administrative_area_level_2',
        administrative_area_level_1: '#administrative_area_level_1',
        country:  '#country',
        postal_code: '#postal_code',
        type:    '#type'
      }
    });

    var gmarker = addresspickerMap.addresspicker( "marker");
    gmarker.setVisible(true);
    addresspickerMap.addresspicker( "updatePosition");


    function showCallback(geocodeResult, parsedGeocodeResult){
      $('#callback_result').text(JSON.stringify(parsedGeocodeResult, null, 4));
    }
    // Update zoom field
    var map = $("#addresspicker_map").addresspicker("map");
    google.maps.event.addListener(map, 'idle', function(){
      $('#zoom').val(map.getZoom());
    });

  });
  </script>

要点是 map 位于具有某些样式的表格内。如果我把 map 放在 table 外面它工作得很好但在里面，这是一个问题...

Answer 1

尝试调用

google.maps.event.trigger(map, 'resize');

页面加载后和每次窗口/文档调整大小后。
