问题 I've successfully implemented google map direction service api : https://developers.google.com/maps/documentation/javascript/directions with 'draggble' option enabled.

问题 I need to make some markers semi-transparent depending on time. Is there any way to control the CSS opacity of a marker? Or is it possible to reliably find out a marker's DOM element? I use Google Maps API v3. 回答1: There is no way via CSS. You could reference the markers in an array, and then loop through the array using the setIcon() method on each marker object to reference icons with different opacities (presuming you're using PNGs with alpha transparency). You'll have to call a function
