说明问题的完整代码可以在显示问题的网页上查看

大部分工作的代码使用查询参数搜索几个 FusionTables 以查找匹配记录，并将地图缩放到所选记录的范围。记录的子集会出现问题，它仅缩放某些记录的一部分（不显示整个选择）。我已将其范围缩小到返回的 kml（从 GIS 覆盖范围生成）包含 MultiGeometry 记录的那些记录。计算出的界限似乎仅适用于记录中的最后一个 LineString。

这是 zoom.js 文件中生成不完整边界的部分

if (geoXml.docs[0].gpolylines.length > 0) {
  geoXml.docs[0].gpolylines[0].setMap(null);                          
  if (i==0) var bounds = geoXml.docs[0].gpolylines[0].bounds;
  else bounds.union(geoXml.docs[0].gpolylines[0].bounds);
} else if (geoXml.docs[0].gpolygons.length > 0) {

这是解析的 geoXml 变量的 kml。

我的代码的问题之一是需要处理每个单独的行字符串，如果是这样，有人可以指点我一个如何做到这一点的例子吗？或者这是 geoXML3 库的错误？

看起来像geoxml3中的一个错误：

http://www.geocodezip.com/geoxml3_test/v3_geoxml3_kmltest_linktoB.html?filename=http://www.geocodezip.com/geoxml3_test/SO_KML_MultiGeometryLineString.kml

似乎没有正确<LineString>计算<MultiGeometry>.

在问题跟踪器中创建了一个问题。

修复了问题。
