Google Maps: Transparent Polygons
提问by Stanley Cup Phil
I have a map that will contain a group of colored polygons. There are times I want to change the fill color of each poly from whatever it is to transparent. I have the following code:
我有一张包含一组彩色多边形的地图。有时我想将每个多边形的填充颜色从任何颜色更改为透明。我有以下代码：
polys[x].setOptions({
fillColor: "#FFFFFF",
fillOpacity: .01, //This changes throughout the program
strokeColor: '#000000',
});
How can I set the fillColor to transparent? Is there a specific hex value?
如何将fillColor设置为透明？是否有特定的十六进制值？

The google.maps.PolygonOptions.fillColoris just that, a color, there is no "transparent" color, that is an Opacity value (0.0 is fully transparent, 1.0 if fully opaque).
所述google.maps.PolygonOptions.fillColor就是这样，颜色，没有“透明的”颜色，即不透明度值（0.0是完全透明的，如果1.0完全不透明）。
fillColor | string | The fill color. All CSS3 colors are supported except for extended named colors.
fillOpacity | number | The fill opacity between 0.0 and 1.0
Update: 0.0 seems to work now for transparent Polygons (jsfiddle)
更新：0.0 现在似乎适用于透明多边形（jsfiddle）
