CSS Google地圖自定義InfoWindow

我一直在使用http://gmaps-samples-v3.googlecode.com/svn/trunk/infowindow_custom/infowindow-custom.html的代碼，這是目前谷歌如何在Maps API v3中創建自定義InfoWindow的最佳示例。我一直在研究它，到目前爲止我已經接近工作，除了一件事情，它的div容器的文本內容不會擴大到適合內容，所以它只是下降，而不是擴大泡沫。如果我給內容容器一個固定的像素寬度，它工作正常，但我不能讓它擴大取決於文本的數量。CSS Google地圖自定義InfoWindow

我被困在這一段時間了。任何幫助將不勝感激！

而這裏的CSS：

.infobox { 
    border: 0px none; 
    position: absolute; 
    width: auto; 
    height: auto; 
} 

.infoboxContent { 
    font-family: arial, helvetica, sans-serif; 
    font-size: 15px; 
    padding: 0px; 
    margin: 9px 0px 0px -24px; 
    position: absolute; 
    z-index: 105; 
} 

.infoboxContainer { 
    background: url('infowindow_bg.png') repeat-x; 
    height: 50px; 
    margin-left: 47px; 
} 

.bubbleLeftDiv { 
    width: 47px; 
    height: 50px; 
    background: url('infowindow_left.png') no-repeat; 
    position: absolute; 
    z-index: 102; 
} 

.bubbleRightDiv { 
    width: 26px; 
    height: 50px; 
    background: url('infowindow_right.png') no-repeat; 
    position: absolute; 
    right: -26px; 
    top: 0px; 
} 

.clear { clear: both; }

謝謝!!

非常類似的問題在這裏討論的一個：http://stackoverflow.com/questions/1554893/google -maps-API v3的信息窗口，不施膠，正確 – 2014-08-15 01:10:48

我遇到了同樣的問題。對我而言，這種方法是動態確定內容的尺寸，並正確設置InfoBox的高度和寬度。我遇到的問題是，在將內容插入DOM之前，它沒有（正確的）尺寸值。結果我的方法是如下：

創建需要插入的DOM內容元素
將其插入一個臨時容器
獲取臨時容器的尺寸
刪除臨時容器
在InfoBox中插入內容並根據臨時容器尺寸設置其高度和寬度

下面是使用InfoBox jQuery框架：

var temp = $("<div class='temp'></div>").html(content).hide().appendTo("body"); 
    var dimentions = { 
     width : temp.outerWidth(true), 
     height : temp.outerHeight(true) 
    }; 
    temp.remove(); 

    var overlayProjection = this.getProjection(); 
    var top_left = overlayProjection.fromLatLngToDivPixel(this.point_);   

    var dimensions= $.extend({}, dimensions, { 
     y : top_left.y - dimensions.height, 
     x : top_left.x - dimensions.width/2 
    }); 

    var div = this.div_; 
    $(div).css({ 
     "top": dimensions.y + 'px', 
     "left" : dimensions.x + 'px', 
     "width" : dimensions.width + 'px', 
     "height" : dimensions.height + 'px' 
    }).html(content);

希望有幫助！

，你可以覆蓋的信息框繪製方法和重新定位的信息框後，已經呈現：

var infobox = new InfoBox(myOptions); 
infobox.initReady = false; 
var oldDraw = infobox.draw; 
infobox.draw = function() { 
    oldDraw.apply(this); 
    if(! infobox.initReady) { 

    // Calculate the required offset 
    var offsetY = -($(infobox.div_).outerHeight()); 
    var offsetX = -110; 
    infobox.initReady = true; 

    // Set the new pixelOffset 
    infobox.setOptions({ 
     pixelOffset: new google.maps.Size(offsetX, offsetY) 
    }); 
    } 
}
