Google 地图 InfoBubble PixelOffset（从标记上方的默认位置移动）

我正在尝试实现一个自定义 infoBubble，它的框打开到标记的侧面，而不是顶部的默认位置。事实证明这比预期的要困难。

使用普通的infoWindow，您可以使用pixelOffset。请参阅此处文档 https://developers.google.com/maps/documentation/javascript/reference#InfoWindowOptions

使用 infoBubble 似乎并非如此。无论如何，是否可以在 infoBubble 中使用 PixelOffset，或者可以做同样的事情？

我发现这个很难搜索，因为使用谷歌搜索这样的搜索不会返回任何相关结果

以下是我一直在使用的所有资源。

• 信息气泡示例here http://google-maps-utility-library-v3.googlecode.com/svn/trunk/infobubble/examples/example.html?compiled.

• 我的 JavaScript 设置地图和 infoBubblehere http://jsfiddle.net/ssrP9/5/.

现在我的 javascript 在这里，以防 jsfiddle 链接损坏。

<script type="text/javascript">

    $(document).ready(function () {
        init();
    });

    function init() {

        //Setup the map
        var googleMapOptions = {
            center: new google.maps.LatLng(53.5167, -1.1333),
            zoom: 13,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        };

        //Start the map
        var map = new google.maps.Map(document.getElementById("map_canvas"),
        googleMapOptions);

        var marker = new google.maps.Marker({
            position: new google.maps.LatLng(53.5267, -1.1333),
            title: "Just a test"
        });

        marker.setMap(map);

        infoBubble = new InfoBubble({
            map: map,
            content: '<div class="phoneytext">Some label</div>',
            //position: new google.maps.LatLng(-35, 151),
            shadowStyle: 1,
            padding: '10px',
            //backgroundColor: 'rgb(57,57,57)',
            borderRadius: 5,
            minWidth: 200,
            arrowSize: 10,
            borderWidth: 1,
            borderColor: '#2c2c2c',
            disableAutoPan: true,
            hideCloseButton: false,
            arrowPosition: 7,
            backgroundClassName: 'phoney',
            pixelOffset: new google.maps.Size(130, 120),
            arrowStyle: 2
        });
        infoBubble.open(map, marker);

    }
</script>

Update

为了帮助回答这个问题，我在此处整理了一个测试用例。重要的行是第 38 行和第 39 行，它们应指定标签的放置位置。

Update 2

为了获得赏金，我需要查看远离标记上方默认位置的 infoBubble 示例。最好在标记的右侧。

Update 3

我已从更新 1 中删除了测试用例，因为它托管在我原来公司的服务器上。

这是我的解决方案。

In InfoBubble library

replace

entire InfoBubble.prototype.draw method

with

/*
 * Sets InfoBubble Position
 * */
InfoBubble.prototype.setBubbleOffset = function(xOffset, yOffset) {
  this.bubbleOffsetX = parseInt(xOffset);
  this.bubbleOffsetY = parseInt(yOffset);
}


/*
 * Gets InfoBubble Position
 * */
InfoBubble.prototype.getBubbleOffset = function() {
  return {
    x: this.bubbleOffsetX || 0,
    y: this.bubbleOffsetY || 0
  }
}

/**
 * Draw the InfoBubble
 * Implementing the OverlayView interface
 */
InfoBubble.prototype.draw = function() {
  var projection = this.getProjection();

  if (!projection) {
    // The map projection is not ready yet so do nothing
    return;
  }

  var latLng = /** @type {google.maps.LatLng} */ (this.get('position'));

  if (!latLng) {
    this.close();
    return;
  }

  var tabHeight = 0;

  if (this.activeTab_) {
    tabHeight = this.activeTab_.offsetHeight;
  }

  var anchorHeight = this.getAnchorHeight_();
  var arrowSize = this.getArrowSize_();
  var arrowPosition = this.getArrowPosition_();

  arrowPosition = arrowPosition / 100;

  var pos = projection.fromLatLngToDivPixel(latLng);
  var width = this.contentContainer_.offsetWidth;
  var height = this.bubble_.offsetHeight;

  if (!width) {
    return;
  }

  // Adjust for the height of the info bubble
  var top = pos.y - (height + arrowSize) + this.getBubbleOffset().y;

  if (anchorHeight) {
    // If there is an anchor then include the height
    top -= anchorHeight;
  }

  var left = pos.x - (width * arrowPosition) + this.getBubbleOffset().x;

  this.bubble_.style['top'] = this.px(top);
  this.bubble_.style['left'] = this.px(left);

  var shadowStyle = parseInt(this.get('shadowStyle'), 10);

  switch (shadowStyle) {
    case 1:
      // Shadow is behind
      this.bubbleShadow_.style['top'] = this.px(top + tabHeight - 1);
      this.bubbleShadow_.style['left'] = this.px(left);
      this.bubbleShadow_.style['width'] = this.px(width);
      this.bubbleShadow_.style['height'] =
        this.px(this.contentContainer_.offsetHeight - arrowSize);
      break;
    case 2:
      // Shadow is below
      width = width * 0.8;
      if (anchorHeight) {
        this.bubbleShadow_.style['top'] = this.px(pos.y);
      } else {
        this.bubbleShadow_.style['top'] = this.px(pos.y + arrowSize);
      }
      this.bubbleShadow_.style['left'] = this.px(pos.x - width * arrowPosition);

      this.bubbleShadow_.style['width'] = this.px(width);
      this.bubbleShadow_.style['height'] = this.px(2);
      break;
  }
};

然后你可以使用它

var infoBubble = new InfoBubble({
  map: map,
  content: "My Content",
  position: new google.maps.LatLng(1, 1),
  shadowStyle: 1,
  padding: 0,
  backgroundColor: 'transparent',
  borderRadius: 7,
  arrowSize: 10,
  borderWidth: 1,
  borderColor: '#2c2c2c',
  disableAutoPan: true,
  hideCloseButton: true,
  arrowPosition: 50,
  backgroundClassName: 'infoBubbleBackground',
  arrowStyle: 2

});

那么最后我们必须使用这个方法setBubbleOffset(x,y);设置 InfoBubble 位置

infoBubble.setBubbleOffset(0,-32);
